Safe to run GPU without VRM heatsinks?

[Andrew_Carr]

Normally I wouldn't do this but I'm trying to test out a build using 1U and that doesn't leave a lot of room for GPUs. I have a semi-functional MSI vega 56 but I need to remove the cover and metal fan shroud that doubles as a heatsink for the misc. parts for proper airflow. The black metal part on the second picture would totally block any airflow coming from the lefthand side. So I was thinking I'd just remove it all and keep the heatsink on, but the heatsink only covers the GPU die / HBM2 memory and not anything else. Do you guys think with good airflow that that would be ok at least for testing purposes? The server looks like the 3rd pic with a bank of fans at the top and I was going to put this GPU closest to them.

I can't say for sure here but as long as you don't stress the card running benchmarks or stress tests I'm pretty sure you would be okay. I've done it on mobo vrms a lot and had no issues.

Ok, thanks. I'll give it a shot.

It'll be fine. I'd probably try to get some heatsinks on there for permanent use, especially if the idea is that you're going to mine this card to death, but if you're just testing to see if the system will work at all with this card in there, it shouldn't be problem.

The metal casing on those IR DirectFETs is actually a heatsink all of its own, and they're VERY tough anyway. I wish they still existed - we'd have a lot fewer dead 980 TIs if nvidia had used those things.

I believe in you, I believe you can fashion some sort of heat spreader like a video card mcgyver!
