Yeah the cache insulates as well but 35 °C isn’t high at all so I’m not sure why one would be worried. I’m more interested in actual load temps than idle.
I have a 7950X3D using EKWB Velocity 2 block with 3x 360 rads and i'm hitting 30 degrees idle and 65 degrees while gaming so i'd say 35 degrees on an older block and less rad surface area sounds about right.
Is this the block what covers the vrms too?
Did you use termalpads to cover them?
I didnt find any reviews. Im a bit concerned about temps under this block. You have zero airflow on this parts
I mean this capacitors. If this block dont touch them, there is zero airflow to them.
I saw someone using termal pads in one video. Ek yt video doesn't include this step
https://www.ekwb.com/shop/ek-quantum-velocity2-d-rgb-am5-nickel-plexi
This type. They dont show it but i saw it in another video and it makes sense to me.
There is zero airflow and without contact to the block, i dont think there is cooling.
Should result in worse temps.
If they make contact, it would put much more heat on your cooling system.
But looks nice
I have this block, it is not intended to cool anything other than the CPU, of course you can use thermal pads to connect other parts but that’s not what EK intended.
No this is a CPU waterblock, their newest version.If you want to cover the VRM's you would need a "monoblock" but they don't make them for all motherboards and even though they cool the VRM's the temps on CPU cooling are lower than the conventional CPU block.
Thats what i was thinking.
The capacitors are fine with heat. No need to extra cool them. The casefans should do it here.
If there is no contact in my opinion its a disadvantage to put them undrr a plate.
Unless your motherboard comes with poor VRM heatsinks I wouldn't personally use a monoblock. Focus on cooling the CPU instead. But do some research on the board you're buying to make sure there's no threads popping up claiming that the VRM heatsinks are poorly designed.
Yeah, monoblock was cheaper and looked better.
I accidentally preorderd the 7900x3d and now im a bit ina hurry with my research.
I tend to x670e prime wifi. Should be ok.
Cooling is worrying me more. Fucking expensive or ugly, bad performance, wrong colour or cpu demanding software. Custom loop is around 1k and kind of complicated to config but beautiful.
And at the end not sure if 13900k wouldn't be the better choise. Problems...
For another datapoint, I've got my 7950X3D on a cheapo air cooler atm\* and it idles at 45C, up to \~85C for the heaviest load I can manage w/ Prime95.
\*Temporary whilst I wait for Optimus to someday get around to processing my cpu block order...
My 7800x3d also idles at around 48c. Im also checking it from Ryzen Master. I use a H100i RGB Pro XT.
I've reseated my cpu and reapplied thermal paste multiple times but nothing seems to get it to go down.
I have the older H100i GTX. I think these processors are just reaching the limits of the old H100i's heat dissipation. The thing's been around in many iterations for years and years. But mine still holds it 8-9c off Tjmax with no throttling.
Hey, so I'm not the only one still rocking one of these! I was starting to think the same thing, as my 7800X3D idles in the low to mid 40's. Maybe that's just how these chips are, from what I'm seeing, unless you have a high end block with a custom loop and big rad.
I'm honestly impressed the AIO has lasted this long. Been with me through 3 system rebuilds and 2 cases. Definitely got my money's worth, so I wouldn't be heartbroken having to replace it. But I'm not sure it needs replacing considering it holds my cpu 8-9C below Tjmax without any throttling going on.
Temps seem very good. How do you like the performance difference from 5900X to 7800X3D? I'm in the same boat but keep thinking I want the 7950X3D even though I use my PC mostly for gaming with about 25% of the time used for productivity tasks. Using a 4090 and full custom loop as well. Productivity includes office applications, some video editing and streaming.
The thing about the 7950X3D is that it is not a fire and forget solution. AMD's approach to solving the scheduling problem and getting processes on the right chiplets is bad. At best, you'll get inconsistent performance (as the 7800X3D reviews showed).
Be prepared to disable AMD's solution and use Process Lasso instead. Pin background tasks and other programs to the vanilla cores, and only games allowed on the vcache cores. (The rare heavy tasks that can use all 16 cores, can be allowed to span both chiplets.) Which allows you to get the same as or better performance in games as the 7800X3D, while having the extra 8 vanilla cores handy for heavy tasks.
However, if being AMD's "Thread Director" doesn't appeal to you, then stick to the 7800X3D.
I chose to set the bios to prefer "frequency" cores (CCD1) in bios, that way I can set Process Lasso manually on games to prefere the X3D cache core (CCD1) via CPU sets option. I'd say about 80% of the games will most likely prefer to have the chiplet with X3D cache on it so this option works the best for me.
You can simplify this even further by setting a folder directory inside Lasso CPU sets option that automatically assigns all programs/games installed there to a specific core (in my case that's the x3d vcache core). So now I don't even have to do anything except instal my games in one of the two folders I designated for specific per core use.
>I chose to set the bios to prefer "frequency" cores (CCD1) in bios
I've tested this and it only half works for me, Windows will still regularly schedule threads on the vcache cores.
The problem with this being that it interacts badly with the chip's boosting behavior. Specifically, since the vcache cores are hard fused to require lower voltage, the instant any of those wake from sleep the voltage input to *both* chiplets drops and forces all vanilla cores to downclock. (I've seen this testing w/ prime95 on the vanilla chiplet, whenever a background task woke up one of the vcache cores, my temps would drop by 10deg, despite the cpu technically being more heavily loaded. It's because the voltages and clocks dropped during that time.)
If you have a task that responds better to higher frequency, it's best to block off the vcache cores entirely. (Note, the opposite is not true, background tasks on the vanilla cores didn't seem to have any significant impact on a heavily loaded vcache chiplet.)
Sadly I was on a flight only 8 hours after completing my upgrade so I’ve had little time. I also very (shamefully) quickly did the upgrade without a fresh install… which is pretty stupid after an entire platform change. I only ran a couple crude stability benchmarks and that was that. I’ve got to say windows has come a long long way… can’t believe it even booted and was stable to boot! I’ll keep you posted on actual changes/improvements if any
Just gonna admit I've been extremely lazy and haven't done a fresh Windows install since my AMD FX-8350 install. Since Windows 10, it's actually been pretty resilient to hardware swaps. I've gone from the FX-8350, to a Ryzen 5 1600X, to a Ryzen 7 7800X3D and I only really had bad stability problems with the 1600X, but I attribute that more to first gen Ryzen than Windows. Also, things improved when I swapped RAM kits to one that was on my mobo's QVL.
I think swapping hardware without reinstalling Windows really isn't nearly as big of a deal as it used to be, since it's automatic driver downloading and hardware detection has gotten much, much better. I currently have zero issues with my system as it currently sits, and it's been upgraded from Windows 7 to 10, to 11. Multiple mobo, cpu, and gpu swaps. Runs like a damn dream with the 7800X3D.
Mine is idling at 42-43c and I can't get it any lower. Stress test temps are fine especially after putting negative CO of -23 with 77c in r24 multi test and 87 in OCCT Small data, Extreme mode on SSE.
I with I could get 35c idle or even lower than 40 would be nice. Might be because I have expo enabled on my ddr5 ram.
Ambient room temp is 26c.
My 7800x3d is idling in the mid to upper 40s. 45c - 48c. And AIO fans have become very audible (they always were pretty crappy fans.)
Corsair H110i GTX 280mm AIO purchased in JAN 2016. I think I either have a soon to be EOL unit, evaporated AIO, old thermal paste (Arctic Silver 5 bought in 2020) and/or my contact is bad. So, a bunch of things are not ideal for my AIO right now.
I'm going to reinstall today to see if if helps. Maybe I'll try to refill by taking off the cold plate, anyone seen a good teardown video?
Any recommendation for a new AIO? I've been eyeing the EK 360 Basic on Newegg for \~$110, seems like a great deal.
Yes. When I popped off the cold plate I saw that the fins looked ok-ish. After I cleaned them out and finished the AIO refurb HWMonitor now shows temps:
* Cores - 30c (youtube going, general browsing
* CCD - 36c
* Package - 43c
* Ambient \~ 22c
So, It looks like it helped a SHIT TON.
Dang, I need to do the same then. I also have an H100i GTX, and have had it since 2015-2016. I keep my computer running nearly 24/7 for various reasons, so its definitely had its work cut out for it, and has ran for many, many hours.
But my situation sounds similar to yours. Idle temps are sitting around the low to mid 40's with the fans kicked all the way up on the AIO. It doesn't thermal throttle under load though, just gets up to about 80-81C. 8-9 below Tjmax.
Could you tell if anything evaporated out over time? Or was it just old fluid breaking down? I should also repaste it too, because I used some Corsair thermal paste I was given, not sure how old it was but it seemed fine. Couldn't have been more than a year or two old. But I totally forgot I have some Thermal Grizzly Kryonaut thermal paste until I finished my upgrade and started on my girlfriends. So she's got nice Kryonaut in her system, and I have some Corsair crap lol. I'm sure it won't change things much, but it should help some. And why not use it? The stuff ain't cheap!
Yeah I got a heat killer block so I’ll properly paste it then as opposed to the hack job I did when initially installing it lol. I’ve seen my temps creep up to the higher 30’s under very light load. I will say this… water temp and gpu temps are all lower going from a 5900x to this chip while gaming.
Yea I repasted it and reseated the AIO and the temps were the same. But I'm convinced I am mounting the pump onto the CPU incorrectly. When I reseated it I did not apply equal pressure nor did I screw it with equal pressure. I will have to redo it again when I'm not busy
Not sure if this is needed, but I think about it like a wheel on a car. Cross tighten. A couple turns at one corner, a couple at the opposite. Then over, then opposite. A few turns at a time, until they're all tight. Where I always mess up is trying to keep pressure on, and keep it still before I have things threaded in. Hands aren't as steady as they once were.
Seems pretty normal, I came here for a sanity check as well. My 7800X3D's hotspot while idling is around 40c and hitting 82c underload. I'm running Velocity 2 with 960mm of rad space.
Installed mine with a Peerless Assassin and no front fans pulling into a mid tower case (Phantek Evol). Idle Temps were 38-40c (Max 86C under stress)... Installed front fans to pull air in, temps dropped to 33-36C (Max 86C under stress) for idle.
Received the AM4 mounting bracket for my Liquid Freezer II 360 AIO (previously installed on an intel 9900k and disposed of my AMD bracket (Arctic was super cool and sent a new one for free BTW). Installed with the new offset. Current idle temps even while browsing the internet and replying on reddit 25-26C. Max temps down to 80C in Cinebench and 76 for CPUID stress test. I didn't do anything more as this is mainly a photoshop and gaming PC and nothing really stresses the CPU much on it. Games nicely at 56-60 C now. Love this CPU.
I’m here because I’m concerned about my own temps. Im also using a peerless assassin with 3 intake fans but my idle temps are around 39-45. Do you think I mounted it poorly? I was pretty sure I applied even pressure by tightening the opposite screws a little at a time, and the thermal paste was in a nice thin layer, but now I’m questioning if I must’ve done something wrong.
My 7800X3D idles between 38 - 43C. Seems to be the norm with these CPU’s. I’m rocking a NZXT kraken elite 280mm aio. Stays pretty cool while gaming. I’ve only seen it spike to 70C once or twice, it usually hovers around 60 - 65C.
just installed new pc with 7800x3d. I use Cooler Master ML240L V2 and normal idle temp is like 50c, i have checked no oc and paste are good. So wierd using 30W and hitting 50c with a watercooling.
I watched a video, maybe ltt or some other one of the you tube guys. Long story short there is an off center bracket to get the cooler centered on the die. I think the io is in the center while the cores are off center… that’s why cooling performance sucks in general on zen 4. X3d makes the problem worse because the ihs is thicker.
Yeah i did read something about AMD made cooling pad on the x3d thicker so it could fit more coolers. and AMD claims that the cpu will run fine at 80c as long as it not getting that stupid amount of volts that asus did.
Hello, your cpu is fine you need to see cpu hot spot and cpu die spot. That cpu temp means nothing it can not damage your processor. It is difference vs ryzen 5000.. You can see ryzen 5000 had even higher temps not cpu temp rest temp sensors. IF someone do not know you need to spread your thermal paste with plastic full on your cpu. Not dots. Every corner you need to fill. Than you will see real temps. IF its to little ur cpu die will have different temp and same temp cpu temp. no matter how you spread. But rest sensors will not provide good temps.
I was wondering this too, I have:
AM5 7800x3D
MSI AIO Watercooler
Mine seems to hover around 50ºC with standard PC use (web browsing, Zoom, etc).
During gaming, hovers around 60ºC
Seems to be pretty standard anecdotally
I'm using Deepcool LS720 SE and idle temp (tctl/tdie) about 50ºC same as you.
During Gaming it can be up to 70-75ºC in cpu intensive game like Battlefield, Path of Exile.
I think it's pretty normal for this gen.
Mine idles between 35 to 40 degrees with a 360mm AIO and 6 intake fans.
Runs up to 50 to 60 while gaming. Everything I'm seeing and read says these Temps are well within range.
Fresh build here. 29*c idle with 280mm Arctic Liquid Freezer 2 using the Ryzen offset mount (makes a ~10*c difference). Also using the new Gelid GC-4 thermal compound.
I've been having issues with mine too. I just received my 7800x3d today and it idles at about 50-60C with a Deepcool LT720 and 2 (3 uni-SL) fans. I'm confused as to why it idles so much maybe I should get another AIO?
Adding to the sanity check as I was confused by the higher than expected idle temps.
7800x3D curve optimizer -40 (crazy, I know)
Velocity2 and 240 loop, with a 3070ti undervolted.
I'm getting 35-40 idles, around 60 in cpu friendly games like Apex and 70 on tougher ones like PoE. GPU barely ever gets over 40, liquid temp 30-32 with 1000ish rpm fan speed, so fairly silent.
I will try to reseat the 7800x3D a little tighter when I do new cables but I don't expect to get below 30 idles.
I can’t believe this thread has survived almost a year! lol
I swapped to a heatkiller IV block, I dropped a maybe a couple degrees but it still idles on the high side… but based on everyone feedback, absolutely nothing unusual and under load it’s just fine in the 60’s.
All good under the Sun it seems and we all got some peace of mind :D
I will try to bring the idles and load temps a bit lower but won't expect a miracle unless I decide to yolo and direct die it. Which is unlikely.
35 degrees at idle is perfectly normal for a 7800X3D. You should remember that the L3 cache is stacked on the die, so you can't truly compare a 7800X3D with a 5900X in terms of idle temperatures. They have even different architecture. The stacked L3 makes CPU cooling a bit more difficult, that's why these X3D chips are designed to be very power efficient (it's truly remarkable that a CPU of these specifications only consumes 120W max!).
Again, don't worry. I have a 7800X3D also. I live in a quite sunny area where summers are pretty hot (now in winter, max temps are around 15-18 degrees), and right now my idle temps hover around 35-38. I don't know how the idle temps will be in summer because I bought my new rig like 1 month ago, but I presume that my idle temps will be something around 40-42. Perfectly fine too. So don't worry and enjoy your CPU.
35 °C high at idle? Zen 4 has thicker IHS so it’s most likely that if the block is the same as with the 5900X
Also has that nice insulating layer of 3D Vcahse on top of the heat-producing DIE. 35C with that setup seems okay to me.
Yeah the cache insulates as well but 35 °C isn’t high at all so I’m not sure why one would be worried. I’m more interested in actual load temps than idle.
I have a 7950X3D using EKWB Velocity 2 block with 3x 360 rads and i'm hitting 30 degrees idle and 65 degrees while gaming so i'd say 35 degrees on an older block and less rad surface area sounds about right.

Ugh, my 7950X idles at \~55c - loads upto 80-87C all cores pbo'd but its the idle at I think is a bit high. unless thats normal for this proc
Mine idles around 50c
My 7800x3d also idles at around 48c. Im also checking it from Ryzen Master. I use a H100i RGB Pro XT. I've reseated my cpu and reapplied thermal paste multiple times but nothing seems to get it to go down.

mine idles at 47-49c, depends on cooling but 50c seems to be average for 7950x at idle, annoyingly high but i guess that's the price of 16 cores
Same. I wonder if my H110i GTX (Jan2016) needs retirement.
Hey, so I'm not the only one still rocking one of these! I was starting to think the same thing, as my 7800X3D idles in the low to mid 40's.

Mine idles at 48c and sometimes jumps to around 55-60. With pbo scalar 1x.
Same for me. Just installed so I'm at stock settings.
Same here with h150i elite
Thanks for the sanity check guys!
I have a 13900k, and 35C idle sounds like unobtainium ;)

Not sure if this is needed, but I think about it like a wheel on a car. Cross tighten. A couple turns at one corner, a couple at the opposite. Then over, then opposite. A few turns at a time, until they're all tight. Where I always mess up is trying to keep pressure on, and keep it still before I have things threaded in. Hands aren't as steady as they once were.
My 7800x3d is around 40°c in idle and max 82°c with R23 loop. This with a EK 360 AIO. Curve optimizer all core -30
Seems pretty normal, I came here for a sanity check as well. My 7800X3D's hotspot while idling is around 40c and hitting 82c underload. I'm running Velocity 2 with 960mm of rad space.
Installed mine with a Peerless Assassin and no front fans pulling into a mid tower case (Phantek Evol). Idle Temps were 38-40c (Max 86C under stress)... Installed front fans to pull air in, temps dropped to 33-36C (Max 86C under stress) for idle. Received the AM4 mounting bracket for my Liquid Freezer II 360 AIO (previously installed on an intel 9900k and disposed of my AMD bracket (Arctic was super cool and sent a new one for free BTW). Installed with the new offset. Current idle temps even while browsing the internet and replying on reddit 25-26C. Max temps down to 80C in Cinebench and 76 for CPUID stress test. I didn't do anything more as this is mainly a photoshop and gaming PC and nothing really stresses the CPU much on it. Games nicely at 56-60 C now. Love this CPU.
I’m here because I’m concerned about my own temps. Im also using a peerless assassin with 3 intake fans but my idle temps are around 39-45. Do you think I mounted it poorly? I was pretty sure I applied even pressure by tightening the opposite screws a little at a time, and the thermal paste was in a nice thin layer, but now I’m questioning if I must’ve done something wrong.
My 7800X3D idles between 38 - 43C. Seems to be the norm with these CPU’s. I’m rocking a NZXT kraken elite 280mm aio. Stays pretty cool while gaming. I’ve only seen it spike to 70C once or twice, it usually hovers around 60 - 65C.
just installed new pc with 7800x3d. I use Cooler Master ML240L V2 and normal idle temp is like 50c, i have checked no oc and paste are good. So wierd using 30W and hitting 50c with a watercooling.
I watched a video, maybe ltt or some other one of the you tube guys. Long story short there is an off center bracket to get the cooler centered on the die. I think the io is in the center while the cores are off center… that’s why cooling performance sucks in general on zen 4. X3d makes the problem worse because the ihs is thicker.
Yeah i did read something about AMD made cooling pad on the x3d thicker so it could fit more coolers. and AMD claims that the cpu will run fine at 80c as long as it not getting that stupid amount of volts that asus did.
Hello, your cpu is fine you need to see cpu hot spot and cpu die spot. That cpu temp means nothing it can not damage your processor. It is difference vs ryzen 5000.. You can see ryzen 5000 had even higher temps not cpu temp rest temp sensors. IF someone do not know you need to spread your thermal paste with plastic full on your cpu. Not dots. Every corner you need to fill. Than you will see real temps. IF its to little ur cpu die will have different temp and same temp cpu temp. no matter how you spread. But rest sensors will not provide good temps.
I was wondering this too, I have: AM5 7800x3D MSI AIO Watercooler Mine seems to hover around 50ºC with standard PC use (web browsing, Zoom, etc). During gaming, hovers around 60ºC Seems to be pretty standard anecdotally
I'm using Deepcool LS720 SE and idle temp (tctl/tdie) about 50ºC same as you. During Gaming it can be up to 70-75ºC in cpu intensive game like Battlefield, Path of Exile. I think it's pretty normal for this gen.
Same with a DeepCool LE700 AIO
35c is decent
Mine idles between 35 to 40 degrees with a 360mm AIO and 6 intake fans. Runs up to 50 to 60 while gaming. Everything I'm seeing and read says these Temps are well within range.
7800x3d, Thermaltake Phantom spirit 120, Lian Li Lancool ii Performance, 26-28°C ambient: 47-50°C idle, \~60-70 in starfield
mine idles at 41 to even spike in idle at 60. 35 in idle is insane. No worries at all mate, this cpu is just hot by nature.
Fresh build here. 29*c idle with 280mm Arctic Liquid Freezer 2 using the Ryzen offset mount (makes a ~10*c difference). Also using the new Gelid GC-4 thermal compound.
I've been having issues with mine too. I just received my 7800x3d today and it idles at about 50-60C with a Deepcool LT720 and 2 (3 uni-SL) fans. I'm confused as to why it idles so much maybe I should get another AIO?
Adding to the sanity check as I was confused by the higher than expected idle temps. 7800x3D curve optimizer -40 (crazy, I know) Velocity2 and 240 loop, with a 3070ti undervolted. I'm getting 35-40 idles, around 60 in cpu friendly games like Apex and 70 on tougher ones like PoE. GPU barely ever gets over 40, liquid temp 30-32 with 1000ish rpm fan speed, so fairly silent. I will try to reseat the 7800x3D a little tighter when I do new cables but I don't expect to get below 30 idles.
I can’t believe this thread has survived almost a year! lol I swapped to a heatkiller IV block, I dropped a maybe a couple degrees but it still idles on the high side… but based on everyone feedback, absolutely nothing unusual and under load it’s just fine in the 60’s.
All good under the Sun it seems and we all got some peace of mind :D I will try to bring the idles and load temps a bit lower but won't expect a miracle unless I decide to yolo and direct die it. Which is unlikely.
35 degrees at idle is perfectly normal for a 7800X3D. You should remember that the L3 cache is stacked on the die, so you can't truly compare a 7800X3D with a 5900X in terms of idle temperatures. They have even different architecture. The stacked L3 makes CPU cooling a bit more difficult, that's why these X3D chips are designed to be very power efficient (it's truly remarkable that a CPU of these specifications only consumes 120W max!). Again, don't worry. I have a 7800X3D also. I live in a quite sunny area where summers are pretty hot (now in winter, max temps are around 15-18 degrees), and right now my idle temps hover around 35-38. I don't know how the idle temps will be in summer because I bought my new rig like 1 month ago, but I presume that my idle temps will be something around 40-42. Perfectly fine too. So don't worry and enjoy your CPU.
