[SOLVED] MSI 1080ti Duke insane temps isues

[RustCohle]

So i have my GPU since late 2018 (after 20 series launch that disapointed me) i do PC maintanance so not so much dust in my build at any time.

I dont remembeexact temps this gpu used to have BUT when i did some OC (used to run about +100 CC/+400 MC I was not reaching temp limit -> bottleneck was chip itself if i understand it corectly but still pretty high temps)
Later on i droped my OC cause i didnt need extra power for titles i played or wokr i done so i went for like +50CC/200MC

Max temp limit is 90 for this model. i did several tests: To eliminate isues of fan curve i just selecket all ma fans on 100% in ALL TESTS

1) UNDERCLOCKED my GPU as much as possible + open side panel (-400/-502 in afterbuner) resulting in 81-84 degrees under stress test.

2) UNDERCLOCKED my GPU as much as possible + closed side panel resulting in 88-90C under stress test.

Such high underclocks are kinda unrealistic scenarios so i did same with stock setings (still 100% fan)

1. default settings + closed case hitting 90C in about 80 sec from 34C
2. default + opem sidepanel hiting 90C in about 110 sec from 33C

My conclusion Case airflow shloud be improved but still it kind doesnt add up does it ? hiting 90C on stock like nothing anyway all fans are spining all seem to be at same speed. its not best model in terms of cooling but it still looks way too bad, ILL try to impove my airflow but i dont expect diference that would be so drastic that my temps would be ok. i was dismanteling GPU to clear heatsink cause of this so this is not dust isue i didnt removve heatsink since i just used all my remaining thermal past on CPU maintanance anyway will buy and do it also.

Does anyone know what alse could i do to fix this ?

For underclocked open

For underclocked closed

For stock +closed

For stock + open

There's no choice but to wait for your repaste results.
That is dang high for an aftermarket 1080Ti. My Gigabyte Gaming OC, for comparison, could be kept under 65C when I pushed it.

Anti-sag bracket - if you're using one. If too much pressure is being applied from below, it could be shifting the heatsink off of the die.

SO paste seemed to be kinda bad i know after removing cooller what remains on gpu isnt how it looked like exactly but 2 siedes seem to be barely touched by paste so i suspect there less paste or just horible paste and so it dried up faster.

After that i runned test with closed case and got way better temps now i even OC +70/+300 and peaked on 78C after 10 mins. Anyway it seemed to be paste i would never expect it would make over 20C diference. I dont know how to flag this thread as solved (or maybe its just admin permision im new here)

2 sides seem to be barely touched by paste

Contact pressure from the cooler cold plate is greater in those areas. The paste only needs to fill in the gaps/pits you can't see.
Too much paste and you end up with excess pooling around the sides of the die. Usually doesn't affect thermals - just wastes paste.
Too little paste and you end up with higher thermals due to missed air pockets.

There is also the matter of what paste you used. Silicon dies are different from the IHS on a cpu. They are smooth like glass; the thicker pastes are more effective with gpu paste applications because of that.

Thanks there used to be default paste from factory now i used theral grizly kryonout....
Also i bought better fan and driled few holes too my case i know RGB fans would kill me for this mindset.


TL;DR - I used to get 90C temp limit in about 90 seconds without OC
Now i get 75 C peak after 15 min strest test while having +70/+300 OC

Careful now, Kryonaut 'burns out' faster under sustained heat loads around 80C or higher. You might have to reapply it again in a year - give or take a few months.
It's one of those small print details that gets overlooked with this paste. The other TG pastes don't have this issue.

Good to know... for now i have very agresive fan curve (even on case fans) so i dont hit high temps unless im on under max load for over 10 minutes in most games i dont even hit 60. Anyway ill keep wathing temps and if they go high ill repaste again.
