Frankenstein GPU solution

 Share

  

In this LTT video they talk about frankenstein GPU cooling, which they conclude isn't really worth it, but I'm in a different situation. In my last post, I talked about buying a 3090, but just the PCB.

 

People told me to not do it since a 3080 isnt that much more expensive, which would perform just as well, but I managed to get my hands on a really cheap ($75) Be Quiet Dark Rock Pro 4, with the 2 fans (which I'm going to sell since I already have extras).

 

Now the main issue is VRMs. Linus used a (aluminum?) heatsink and some thermal adhesive. But he also said it's not effective permanently. What is a more permanent solution? And what are good quality, cheap heatsinks? And finally, where do I NEED to put them on the board? Thanks!

Heatsinks are not the problem, issue is lack of airflow to have them effectively cool. You also have make sure you are putting just enough pressure on the GPU die and backplate otherwise you will crack your GPU die, crack your PCB OR cause your GPU to seperate from PCB.

 

Overall this is not just just slap a CPU cooler on it and use it type of situation, I dealt with direct-die previously I personally would have picked 3080 instead.

Hi there, for VRM i would use something like these:

Problem is as Levent said: Airflow.

if i recall correctly, the Vrm get very toasty on these things so you need to attach them with a good heat transfer aswell.

difficult, but fun project.

CPU: AMD R9 5900X GPU: Powercolor 6950XT Liquid Devil Board: MSI MPG X570 Gaming Edge Wifi Ram: 32GB Corsair Vengeance LPX Black DDR4-3200 CL16 PSU: Seasonic Prime PX-1000 Case: BeQuiet!

Those two things are inherently opposite.

 

As for the cooling, I would go for a flat style cooler, or a slim tower in order to cool the VRMs and power delivery components with individual heatsinks and 92mm fans ziptied to the board, it won't look pretty but I think it'll be able to keep temps at acceptable levels while playing a game or whatever. Another thing you can do is use a thick single fan AIO cooler to take care of the GPU and leave the board in better condition for the heatsinks and fans.

Tender is the night

and don't forget the 3090 has RAM modules on both sides of the PCB

 With all the Trolls, Try Hards, Noobs and Weirdos around here you'd think i'd find SOMEWHERE to fit in!

with the cooler I will have sideways airflow, which should flow through the heatsinks. If not, I'll attach another fan I guess.

ya, I'll put some heatsinks on the back too. Do you know of any good thermal tape/adhesive?
