What is the most important part to cool on a gpu?

[Sam Harradine]

Hi, i have 2 windforce 980 ti's in my h440 (old) and they get really hot. so im thinking about watercooling them. Obviously i have overclocked and want to further. But im stuck, should i get full cover block from ek? or can i half the costs and get either just a uni block or a kraken g10 and some vram and vrm heatsinks?

You might just wanna improve your airflow. The H440 already has generally bad airflow.. I think a case with better airflow would improve the temps.

The absolute most important part is the core.

It's important that all of the components are cooled.

Most important order is probably GPU<Vram<VRM

aka everything

I might change that to GPU<VRM<VRAM. If the VRM gets too hot, the GPU will throttle or something worse might occur. However, I would want every component cooled, and none neglected.

If the VRAM becomes to hot it could also throttle cause general instability, could it not?

I'm the same and would want every component cooled as well tho.

Exactly. Air coolers are cooling everything too ...

The VRM is delivering a lot of power to the GPU, and if it isn't cooled sufficiently, it could be more catastrophic.

@LinusTech should test which is more important to be cooled.

currently i have the front and top panel off. with two 140mm noctua industrial faans as intakes, a gamer storm 120mm rear exhaust and my 360mm rad up top with nf-f12's on it. but now the rad gets way hotter being at the top.

i know, but the £250 extra is a real deal breakers. so im in quite a predicament, and also if i get the bracket i can use it on future gpu's most likely

yeah... waht if they melt? HUH?!

I'd flip that completely: GPU>VRM/VRAM... the core is going to throw out way more heat, is it not?  So, wouldn't it be the most important thing to cool just based on that alone?

I meant that as the GPU coming first.

So the core is the hottest part right? i guess seeing as that's where the heat pipes go. But how much difference is just cooling the core compared to normal? i dont like the heat, especially cause it's an sli set up in a h440

If you're pushing high current through the VRM, it could overheat causing throttling on the GPU or, even a fire if there are no safety precautions in place(not something I can answer). The only thing on the VRM that needs to be cooled are the MOSFETs(the transistors).

oh. Well those less than/greater than was confusing; I read that as GPU<VRM, as in, GPU less than VRM, as in less important

Just for you, here: GPU>VRM>VRAM.

just get a goddamn fullblock, why cheap out if youre already on sli. stay air or do it right

Well i don't know how long i'll be keeping the 980's for that's all. I guess now you say it it makes sense
