Zotac 1080ti (3 fans) overheating and thermal throttling extremely bad

[Overtime]

Without any overclocking, my 1080ti has recently been getting extremely hot and throttling down under base clock in any full load. Any idea how to fix it? It's a 3 year old card if that helps, all 3 fans spin. 

 

My case does have pretty bad airflow, but the thermals are almost the same with the entire pc side panel off, so I don't think it's an airflow issue.

 

Here's a video of it (sped up 800%)

 

Thanks!

 

 

(I set a temperature limit at 84 degrees in Afterburner because it would constantly jump to 90 degrees+ and shut my computer down when playing games.)

Try reapplying the thermal paste; you don't have warranty support anyway. Also make sure its clean.

As what ^^^ said, make sure and blow out dust in the fins to, try undervolting if none of that helps

Is the heat sink clogged with dust?

I've cleaned out the card completely, it didn't help as it was relatively clean already. I also tried lowering the core voltage % and power limit on afterburner with barely any difference

I don't have any thermal paste on-hand right now but I'll order some asap, hopefully with minimal shipping delays.

 

Thanks!

Make sure to get non conductive!

 

most paste is non conductive, but I know there’s a few that are, can’t remember by name.

YES this is extremly extremly important. Unlike CPUS, the GPU die need to be fully covered because it could have hot spots so you can't really overdo it (Jayz2Cents puts a LOT on it). However you need it to not conduct because if it is conductive it could fry the GPU. IC Diamond is reccomenended by many people and Linus himself and I have used it in the past (its not conductive).

Can you make sure that the screws are still tight that hold down the heat sink? Over time vibrations from the fans can make them loose.

Doubt this, fans barely vibrate, and the screws are spring loaded.

Lots of thermal pastes on amazon/newegg in my area aren't available or are very expensive, do you think the Noctua NT-H1 would do the trick? It's non-conductive on their website and is at a reasonable price.

Yes that would be perfectly fine. Noctua makes great products.

I'll order some right now, thanks for all your help!!

The screws for the backplate of my zotac 1080 amp extreme where very lose on two and a bit lose on one screw.

 

I used Thermal Grizzly Kryonaut on my gpu and it worked wonders. 13 °C cooler with half the fan speed.
