Temperatures are at 72C at 1950 Core / 7752 Mem / 100% fan

Thanks for your help.

The hottest my 2080 ever gets under max load gaming is around 75C, and that's with a pretty aggressive overclock and the stock fan curve.
Yeah, good point.

@Sriram_Thodla regardless of having your GPU temps under control now, I still recommend that at some point you change your top radiator fans to be as exhaust and see the results.

Even with only one intake on the front you may see improvements in CPU/GPU temps.

Because those are fans on a radiator and between them and the card you also have the CPU section (with VRMs and stuff that also produces heat), you are pushing hot air down, against your backplate card, not letting the heat that comes from it go up (as naturally hot air goes up).

I believe your system would benefit much more if your top fans where pushing air out, not in.
As far as my research and personal testing goes, the only scenario when using radiator fans as intakes is good is when located in the front of the case.

The front intake fans are controlled by Corsair Link and ramp up based on coolant temp to 80% or so at 33C (which I usually don't reach gaming). I have my exhaust fans controlled in the BIOS and set to ramp up based on CPU or GPU temp (maxing out around 80% over 75C), except for the bottom intake fan which only looks at the GPU temp. I use the thermal probe on the back of my GPU die to get something close to the GPU temp for the BIOS. I have all the fans going at a minimum of 40% at all times (might as well since they're really quiet).

juan197 Has anyone tried without problems any bios with more PL for the Gaming X Trio?

Há! I thought about asking you this but I imagined you had checked already haha.

The 2 fans of the GPU are not pushing air down, you can feel the air because it's a narrow space but they are actually pushing the air to the back of the card.

Sriram_Thodla Also - I'm a little confused about fan placement for GPU. Why are the two fans facing down pushing hot air down? Wouldn't it make more sense to have them facing up? However all the builds Ive seen have fans facing down.

Sriram_Thodla Makes sense thermally. I'll try that tonight.

Btw I have one intake fan in front. One exhaust in back. 2 intake at the top.

Sriram_Thodla Did a open case benchmark. Hit 83 degrees. Doesnt look like an airflow temp trap issue. Could still need fans.

Returned it to stock and hit 77 degrees. Idle is 35 stable.
