Nvidia Tesla P40 24GB AI Fan Mod from a GTX 1080 Refence Cooler

[@modx5534]

Very cool! Thank you so much for sharing :D

[@MaverickTangent]

thanks! hopefully I'll get it installed here soon... and try it out.

[@MaverickTangent]

hey, I made a part 2 video showing this card working in a computer. it does really good, but the fan at 100% is really loud.

[@richardsontm]

FYI the GTX1080Ti has almost an identical VRAM layout as the P40 on the front side. It is a better fit than the GTX1080 reference cooler on the P40 PCB, as you don't have to use thicker thermal pads on those additional VRAM modules in the corners.

[@MaverickTangent]

that's good info. I made a part 2 showing that the card works fine, if you want to to check it out. but the fan at 100% is loud.

[@13G0Pr077]

Awesome work ! I am curious how it performs. Please let us know. If it works fine I will have to search for parts to install blowers this way to P40s (24 GB Vram

[@MaverickTangent]

I works SO much better, I just uploaded the follow up video. It generated images in stable diffusion in seconds, not 6 minute, etc.

[@mdisieno]

Could you please link the cable you have for the fan? I bought the same cards (GTX 1080/P40) and would like to mirror your setup.

[@MaverickTangent]

@michaeldisieno3465 just a 4 pin pc fan "extender" with a female on one side and a male on the other. I'm not posting any links.

[@RobertFixit]

I have a tesla K and the 980 heat sink bolted right on. Same situation though no fan power. Mine runs a 80mm standard case fan. We both think outside of the box 🤘

[@MaverickTangent]

@@RobertFixit I did think about just sticking a 120 fan on it

[@RobertFixit]

@@MaverickTangent But if yours is like money the grills at the top are closed so only sideways air can go through But knowing its a standard 1080 pattern, any 970/1070 and up should fit as long as it doesnt hit the parts on the board I am definitely going to look for one of these cards.

[@MaverickTangent]

@@RobertFixit remember I have the heat sink from a GTX 1080 on mine.

[@vyax]

have you tried adding more vram to a lower end card? A lot of this gen is artificially limited on vram to make ai inference require the more expensive cards - even though the slower ones would be capable.

[@MaverickTangent]

Waste of time. The cards with more ram are cheap and this was a low effort project. Maybe 30 min total. The amount of labor and tools required to add ram to a cheaper card isn't worth the effort. And you have to program a custom bios. Which I can't do. Not worth the effort for the surplus of cards out there. With the amount of money I have in this, I am only $50 away from an A2000, which is a better card in every way. As of 2024.

[@vyax]

@@MaverickTangent I've seen vram mods out of china, seems pretty cost effective but good to hear your experience

[@MaverickTangent]

@vyax I just don't have the equipment to do the heating of the board, etc. And for me to buy that, I might as well just get one of the better cards. Unless I need like, 100? I'm actually shocked this 1080 cooler fit. It was just a hunch.

[@gonzalodijoux5953]

hi, do you have a model or a link for new heatsinker and fan for P40 on aliexpress or temu. My link was erased. thanks

[@palmodovar2015]

Ok and where can i search the driver?

[@MaverickTangent]

the only way to make this P40 card work in Windows is to install the nvidia cuda tool kit. see my part 2 video

[@saxinat0r]

Have you installed it? How it it holding up?

[@MaverickTangent]

@saxinat0r I haven't used it yet. I'm doing some things for work on my lab hardware and I haven't pulled it apart to set it up for AI yet... I'm just as curious as you. lol

[@MaverickTangent]

I made a part 2 video, if you want to watch it. the fan is just hooked to 12v using a sata adapter so its loud but it does work if you install the nvida cuda toolkit. check out my part 2 video

[@saxinat0r]

@@MaverickTangent nice! Can't wait to watch it tonight. Thanks for the heads up

[@MaverickTangent]

@saxinat0r with the 4 pin fan hooked to a sata power plug, the fan runs 100% and it hits 54C under load. So I am gonna get a reostat to turn it down to maybe 70% fan speed. Target 70-80C under load and make it quieter

[@saxinat0r]

@@MaverickTangent have you found a way to automatically adjust fan speed based on the card's temperature?

[@wagnerribeiro8036]

How is this mod holding up with time/usage? Can I commit? Hehe

[@MaverickTangent]

I haven't run it. I got the power adapter cable and the fan extension should let me plug it into a PWM om the motherboard. Just need to pull my other card out. Been busy.

[@MaverickTangent]

hey, I did make a part 2 - it works fine, if you want to see my follow up video. you have to install the nvidia cuda toolkit and the fan just runs 100% using a sata to 4 pin adapter

[@k1tajfar714]

I wish i could get your modded P40. I'll pay 200$ bucks for me (I'm from a 3rd world country so that's all i have lol)
