Sriram_Thodla Ok - I figured out the problem. For some reason MSI afterburner was not following my custom fan profile and was setting the fan at 0% (that's right - no fan). It was when I was messing with different settings that I accidentally turned off user fan profiles and heard the fan switch on.

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

Thanks for your help.

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.

Yeah I saw from your pictures.

Regardless of your GPU temps, I don't think your top fans should be intakes.

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.

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.

fleps And you know what? I just took a look with more attention on your case photo and if you are up to, do a crazy test: turn your front fan OFF and run the benchmarks, with my fan curve applied on your card.

My case is way bigger than yours so my front fans are a good 20cm away from the card.
So thinking it was too far, I installed a fan very close to the card, much like the distance you have, and my temps GOT WORSE.

I don't know why, maybe the air turbulence / flow started to interfere with the second fan of the card, or interfered on how the heat from the VRM sections should be blown to the backplate and not blown into the cores direction, I just know that my temps raised a good 5 or more degrees.

It wont hurt doing this test.

Temp idle is about 30c. I might double up on intake and exhaust fans if that's the problem.
Well, I think you have too much intake for just one exhaust on the back for such a small case.

You could try to put the ones in the top as exhaust as you already have 2 intakes in the front which should be fine

But regardless, I don't think change this would make THAT much difference comparing your 83C vs the 65C I'm getting which is the same result from the review I posted before.
To just discard anything with your case fans you can run a few benchs with the case open and see.

What fan curve are you using on the card? Attached is mine in case you want to test.

EDIT: yeah I noted later on that the review was not for the same model. Regardless, I still think is too high.

So these cards temperatures should be really close, and yours even lower IMO as your ambient temps are almost 10C lower than mine.



Regarding your top fans, it do you also have a back fan exhausting? When benchmarking you should feel the air coming out hotter, on idle usually isn't much.



How is your card idle temp? Mine is 43C right now with 24% fans on 1230Mhz core (lower idle allowed when using 2 displays). And it's freaking 29C ambient at 7 pm lol.



You can do a few benchmarks with your case open just to make sure is not a case fan, but I don't know, it seems this card need to be returned or have paste re-applied.



EDIT: here's a review of your model particularly the temps page, where while gaming/furmark their card didn't get above 65C: https://www.tomshardware.com/reviews...mp,5839-5.html
Btw. I have zotac rtx 2080 twin fan. The link you sent was for the model above mine with 3 fans.

For Zotac It goes from basic to high end.

Blower
Twin fan
Amp
Amp maxx
Amp extreme
