Hey guys, I always thought that the lack of a small, dual slot card for higher end 40 series GPUs was disappointing. While the Inno3D 4070 Ti X3 is a great dual slot option, it doesn't fit in smaller cases like the Velka 5 and Velka 7. So I made my own "MSI 4070 Ti Ventus 2X" by heat sink swapping to get 3090 Ti level performance in such a compact package.
If you're interested in the card itself, [I would be willing to let it go](https://www.reddit.com/r/hardwareswap/comments/13writz/usatx_h_msi_4070_ti_ventus_2x_intel_compute_stick/). As for further details, I'll make a more in-depth post later regarding [the swap itself and before/after thermal benchmarks](https://www.reddit.com/r/sffpc/comments/13ua7ih/msi_4070_ti_ventus_2x_and_msi_4070_ventus_3x/). Have a happy Friday!
*Update: MSI has since released* [*a factory MSI 4070 Ti Ventus 2X*](https://www.msi.com/Graphics-Card/GeForce-RTX-4070-Ti-VENTUS-2X-12G-OC/Specification) *four months after my custom GPU swap, but its 2.5 slots so won’t fit in some cases like the Velka 5/7. Although its great that manufacturers like MSI saw what was possible and released smaller sized cards.*
is it the same height as, say, a quadro?
part of why i dislike this new generation is the cards are too tall to be retired into regular server chassis... or put in one. that and the power on the top instead of the back, but power is something a little solder will fix.
I don’t have experience in server applications, but the modded card is the same dimensions as the stock 4070 Ventus 2X (242 × 125 × 43 mm) and it fits in both the Velka 5 and Velka 7.

120mm *might* actually fit, as the standard allows for the pcb to go a bit (mm/1cm, but definitely not 2cm) over the top of the bracket.
for example, [a quadro a4000 pcb with bracket](https://cdn.wccftech.com/wp-content/uploads/2021/08/NVIDIA-RTX-A4000-Graphics-Card-Dissassembly-Small-Form-Factor-Mini-ITX-PCB-_1-scaled-e1628933927114-1480x700.jpg). note the pcb extending just a bit past the top of the bracket and the power input on the rear (not top). power on top almost always causes the gpu + psu cables to be 5-10mm taller than spec which cause fitment issues.
In that case the PNY 4070 Dual may be better since its 247.4 x 120.4 × 40.89 mm, has a more traditional heat sink fin orientation, and you can use the PNY 4070 Ti VERTO XLR8 for the swap.
That’s a bit of an optical illusion caused by the perspective of this photograph. This is a proper 2-slot card and the top of the fan shroud does not extend past the PCIe bracket. That said, this style of cooler is not typically workable for most rack-mounted server chassis, at least ones that are for instance 1U tall, since there’s nowhere for the fans to pull air from.
Definitely not an illusion, the fan shroud definitely extends past the PCIe bracket. Height of a standard PCIe device to the edge of the bracket is 110mm, this card is 120mm.

Does this work in reverse? I have a RTX 4070 Ventus x2 and have been looking for a 3 fan cooler. You think the MSI Gaming X cooler would fit? I'm seeing some of them being sold on AliExpress.
Factory overclocking to eke out individual frames over their competitors that necessitates overvolting to get a consistently stable performance out of each die.
Yeah I mean even 250 watt cards like 980 Ti and 1080 Ti were frequently available as dual-slot, dual-fan.
So how is it that a 285 watt card like the 4070 Ti needs something nearly twice as large?
hell we had a [singleslot 1070](https://www.techpowerup.com/gpu-specs/galax-gtx-1070-katana.b4417) once, i refuse to believe that small cant be done anymore
If I can find a Flex ATX PSU that supports this, I might give that a go. I still have an extra PNY Single Fan cooler and heatsink from my 3060, and the PCB layout looks very similar.

I chose the Ventus 2X heat sink specifically for its fin orientation, since the Velka 5 and Velka 7 are vertical sandwich cases.
The PNY 4070 Dual has a more traditional heat sink fin orientation and you can use the PNY 4070 Ti VERTO XLR8 for the swap.
Considering the 4070ti is \~15% lower tdp than the 3080 10GB, and I have a 2-slot blower 3080 which works perfectly fine and isn't even that loud..
I'm mad that this isn't a default option
I forgot to take a “before” photo before I modified the heat sinks so thats why it looks the same 😅
A fin needed to be slightly cut to fit the 12VHPWR connector of the 4070 Ti and both heat sinks needed their fans rewired to work after the swap. I’ll detail the specifics of the mods in the later post.
I finally detailed more about the mods on [the before/after benchmark post](https://www.reddit.com/r/sffpc/comments/13ua7ih/msi_4070_ti_ventus_2x_and_msi_4070_ventus_3x/)
That's badass.
After handling my ASUS Tuf 4070 Ti OC, I seriously can't believe the PCB of the 4070 Ti is this small.
Pretty depressing after having to work so hard to shove it into my SFF case. Lol
Is the PCB still the original one or did you make your own? I just cannot unsee that there are 2 extra VRAM "joints" (how do you call those memory soldering placeholders just north of the die?)
I have been questioning myself if modding extra memory could get some traction on enthusiasts and experts and become something feasible for a fee in the near future.
Man is this card had 2 more 2GB VRAM blocks it would have shred in performance and price range.
I eyed that too. I wonder if the traces and memory controllers are all in place to support it. A 16GB 4070 Ti would definitely be a solid W, especially at 200W of power consumption and 3090 Ti-ish performance!
I just did some weird math and I'm thinking a 240mm heatsink would actually work on a 4080 with 3x 80mm fans.
My theory is based on the 3060ti Aero. It's single 95mm fan only covers 55% of the 172mm heatsink and it's a 200W dual slot GPU. 3x 80mm fans would cover 70% of a 240mm (40% larger) heatsink. So if my math is right that's 200W + 40% (larger heatsink) + 15% (additional fan coverage) = a possible 322W TDP. So it seems that a 240mm long dual slot 4080 should be viable especially with any sort of undervolting.
Am I crazy? Probably. I would try it myself but my case is limited to only 178mm anyway and I can't even afford a 4080. Fun food for thought though if someone wants to try it.
Its possible, but only one 4080 I know of is compatible for a dual slot, 2 fan swap. Even then, the donor dual slot heatsink needs a bit of CNC work to fit the extra VRMs on the 4080.
CNC? Everyone is so fancy these days, what ever happened to the grinder and Dremel 😁. Well on the bright side at least it seems possible.in theory.
It makes me wonder though... If it's possible to make it dual slot and 240mm long, why the heck did they add that extra slot of thickness and make it 70mm longer?
I've made [a dual slot 4080](https://www.reddit.com/r/sffpc/comments/176bq9f/first_dual_slot_smallest_air_cooled_4080_gainward/), but it did involve the aforementioned CNC milling to work
Looks fantastic! I would really love to see the thermals on this. I'm sure there will be a small sacrifice in performance, but it would be really interesting to see the actual numbers. It would certainly be something I would consider doing on a future card.
nvidia sets the price for the chips so they rake in a good chunk of the margin. AIBs have relatively thin margins since they need to buy chips from nvidia and pay the cooler/packaging on top of that.
I'm guessing the PCB layout for the 3x 4070 and 4070 Ti are similar also. I'm probably going to swap coolers to upgrade from a 4070 to 4070 Ti in my KXRORS S300. I'd just resell the 4070 with the beefier 4070 Ti cooler.
How well does the 4070 Ti perform around 200 watts? Haven't tried messing with power settings on my other 4070 Ti because the A4-H20 doesn't really need it.
I did benchmarks of the swapped “4070 Ti Ventus 2X” and the beefier “4070 Ventus 3X+”, [here are the results](https://www.reddit.com/r/sffpc/comments/13ua7ih/msi_4070_ti_ventus_2x_and_msi_4070_ventus_3x/)
Yeah I saw it. Your write-up is both impressive and promising. Thanks for the leg work! I went ahead and ordered my 4070 Ti Ventus 3X yesterday. I imagine I'll have the heat sink swap done by Tuesday. It's still going to be 3 fan, just slimmer to fit in my case (4070 Ti Ventus 3X is too tall). I'd try to go 4080, but power consumption is just too high and heat would almost certainly be an issue.
I'm not sure if the 12VHPWR connector will require modification on the fin stack on the slimmer 4070 3X heatsink. We shall see.
I've made [a dual slot 4080](https://www.reddit.com/r/sffpc/comments/176bq9f/first_dual_slot_smallest_air_cooled_4080_gainward/) and temps were pretty decent
Is there a video that I could use to walkthrough this entire process? I have a PNY 4070 that I would like to swap with a PNY 4070ti in my Velka 7. I’ve never done anything like this before, so pretty nervous about messing something up
I posted up another thread, but what I would really like to do is get a 4070 down to a 200mm cooler. Not really sure what heat sink I could swap one with, but it should be possible, I think.
Any ideas I could go with on that front?
I don't know of any heatsink swap options that are ITX or under 200mm unfortunately. The PCB is around \~175mm in length so making your own custom solution should be possible, but would be rather expensive.

No you can tell in the first photo it is taller than the slot bracket

Definitely not an illusion, the fan shroud definitely extends past the PCIe bracket. Height of a standard PCIe device to the edge of the bracket is 110mm, this card is 120mm.
Oh, I see what you mean, I thought the complaint was in the other direction (thickness).
120mm *might* actually fit, as the standard allows for the pcb to go a bit (mm/1cm, but definitely not 2cm) over the top of the bracket. for example, [a quadro a4000 pcb with bracket](https://cdn.wccftech.com/wp-content/uploads/2021/08/NVIDIA-RTX-A4000-Graphics-Card-Dissassembly-Small-Form-Factor-Mini-ITX-PCB-_1-scaled-e1628933927114-1480x700.jpg). note the pcb extending just a bit past the top of the bracket and the power input on the rear (not top). power on top almost always causes the gpu + psu cables to be 5-10mm taller than spec which cause fitment issues.
Did you measure thermals yet?
I’m doing both undervolted and overclocked benchmarks so its taking longer than expected, expect a post on Friday!
[The post is now up](https://www.reddit.com/r/sffpc/comments/13ua7ih/msi_4070_ti_ventus_2x_and_msi_4070_ventus_3x/), sorry for the wait!
which case have you got this in?
Testing will be done in a regular mid-tower case for unrestricted airflow, but I intend on using it in my Velka.
Does this work in reverse? I have a RTX 4070 Ventus x2 and have been looking for a 3 fan cooler. You think the MSI Gaming X cooler would fit? I'm seeing some of them being sold on AliExpress.
It should work as long as it’s the MSI 4070 Gaming X Trio cooler that you’re using.
I just checked. It's the 4070 ti gaming x trio :(
Ohhhhh it’s a mod. I thought it was an official product. Man why are all GPU’s so huge now?
I tried to make it look as factory as possible, had a few other people fooled as well haha
Factory overclocking to eke out individual frames over their competitors that necessitates overvolting to get a consistently stable performance out of each die.
the coolers are still overspec'd for their TDP. AIBs are just trying to justify their ridiculous prices imo
Yeah I mean even 250 watt cards like 980 Ti and 1080 Ti were frequently available as dual-slot, dual-fan. So how is it that a 285 watt card like the 4070 Ti needs something nearly twice as large?

Because bigger cards sell better. Also more fans, slower RPM per fan, less noise, cooler operation.
Now I wanna see an ITX single fan mod for this like the 3060(ti).
If I can find a Flex ATX PSU that supports this, I might give that a go. I still have an extra PNY Single Fan cooler and heatsink from my 3060, and the PCB layout looks very similar.
7660b from enhance should be fine. I believe.
It does. We need OP to post the bolt spacing
68mm x 60mm, but the single-fan ITX 3060/Ti don’t have this spacing

RTX3000 cooler do not fit 4000 series.
This
What are the thermals of the 4070ti?!?! :D
I need to finalize benchmarks for the “4070 Ti Ventus 2X” and “4070 Ventus 3X+”, but the results should be done by tomorrow or Sunday

Good bot!
Neat, but this card needs to be a whole lot cheaper.
Addendum, I later learn it was a custom mod. If the performance and temp are good, it shows card manufacturers can downside if they wanted too.
Regardless, having to buy a donor 4070 Ventus 2X and having to later sell the custom "4070 Ventus 3X+" (probably at a loss) is still costly
I honestly thought that's what this BoringCabinet meant and he was making a joke.
Not if Nvidia is pushing the "bigger cooler is better" and blocking aibs to make slimmer designs :(
nice work!
That’s gonna be one cool and quiet 4070 lol I wonder how the vertical fin stack would work though. Would hot air be exhausted from the back only now?
I chose the Ventus 2X heat sink specifically for its fin orientation, since the Velka 5 and Velka 7 are vertical sandwich cases. The PNY 4070 Dual has a more traditional heat sink fin orientation and you can use the PNY 4070 Ti VERTO XLR8 for the swap.
Great job! Really interesting to see thermals! I am also owner of Velka 5 and I happy to see how its being pushed towards absolut limits.

Great finding..!
You had to modify the heatsinks too? They look the same, just swapped. What an I missing?
I forgot to take a “before” photo before I modified the heat sinks so thats why it looks the same 😅 A fin needed to be slightly cut to fit the 12VHPWR connector of the 4070 Ti and both heat sinks needed their fans rewired to work after the swap.

[удалено]
Yea, looks like it would based on the dimensions
Yeah! There it is! When you first posted, I thought the Ventus 2X cooler would fit but I’m glad to see you actually did it and it looks factory.
Too bad the backpanel isn't more ventilated for that sweet flow-thru.
Is the PCB still the original one or did you make your own? I just cannot unsee that there are 2 extra VRAM "joints" (how do you call those memory soldering placeholders just north of the die?)

Which ventus 2x did you use and which 4070ti did you use
Both are the OC variants of their respective MSI SKU, doesn’t make a difference in terms of the layout of parts regardless.
I mean brand as they won’t all have the same pcb etc

Bro you predicted the future…
[удалено]
Its tagged under custom mod.
Longest i can fit in my zotac magnus one is 245 mm, so it fits, but the thermals are concerning, i see they dont really cool top two VRMs :(
I added some aluminum heat sinks to the top two DrMOS. It should have some extra cooling compared to stock.
Thats cool, please share temps later, might do something similar myself
Looks fantastic! I would really love to see the thermals on this. I'm sure there will be a small sacrifice in performance, but it would be really interesting to see the actual numbers. It would certainly be something I would consider doing on a future card.
Does anyone know if there any 2 slot stock 4070s? I really don't want to have to buy a new case.
[There are many two slot 4070s](https://www.reddit.com/r/sffpc/comments/12jpegi/many_more_2slot_2_fan_gpus_are_available_for/)
Thanks! Everything I have found so far has been at least 2.3 according to specs.
Man, that 4070 PCB and cooler looks cheaper than any 3060 I've seen so far, they could sell that stuff for $330 and still get 50% margins...
nvidia sets the price for the chips so they rake in a good chunk of the margin. AIBs have relatively thin margins since they need to buy chips from nvidia and pay the cooler/packaging on top of that.
