Overheating 2080ti FE

[MongooseMonke]

Specs:
CPU: Ryzen 7 5700x

CPU cooler: ThermalTake Pearless Assassin 120mm

GPU: RTX 2080ti Founders Edition

RAM: G. Skill Aegis 16 3200mhz cl 16

MOBO: Gigabyte b450m ds3h

PSU: Corsair cx550m

Case: NZXT H510

Fans: Thermalright TL-C12C-S CPU Fan 120mm (2 facing in from the front, 2 on the cpu cooler, 2 facing out (one in the top one in the back))

My GPU temperatures have been hitting 86-88C at full load (playing games like cp2077 and FH5, also while benchmarking). I have not overclocked the GPU at all and have tried undervolting it but it only helps gain some FPS and there is no help to the temperatures. If I go with a more aggressive undervolt my games just crash. I also have tried turning my fans for my case and GPU all the way up which didn't help significantly, I have replaced thermal paste and pads, opened the side panel, and used compressed air to clean the fans (I can't get into the actual vapor chamber or parts of the fans because that part of the GPU can't be taken apart). I feel like I have tried almost everything. I also know 2080tis are not the most power efficient but surely they aren't supposed to get this hot with good airflow and a cool ambient temperature. I have also heard that the NZXT h510 does not have the best airflow but I have removed the whole side and back panel which has not helped at all.

Any help would be appreciated

Sounds like it needs to get re-pasted, which means opening up the GPU, cleaning the old thermal paste and applying the new one.

 

The hotspot temps might be hitting critical levels, which is why undervolts have same temps. The GPU is likely throttling because the average temps you mentioned are approaching 90C.

 

Since opening sidepanel doesn't help much, re-paste is the only option.

I have already repasted only about 5 days ago

did you clean the old paste and made sure the new one is nice and spread?

 

if you want better sensor readings, get this: https://www.hwinfo.com/download/

 

see how warm the hotspot temperature is

Also did the re-paste improve temps? If you know temps before repasting?

I checked hotspots with hwinfo both before and after and the hotspot dropped from 104 down to 102 but neither are ideal obviously. Temps before and after (non-hotspot) are both at 88 with throttling

how are the GPU fan speeds in %?

 

if you repasted the card, and tried everything from opening side panel, to running fans at high speeds, it might be worth to take a look under again,

 

opening the GPU and seeing how the thermal paste spreaded, if there's even a small area on the die that is missing paste or has very shallow amount of it, like in a very noticeable way, there might be that problem.

 

What paste did you use? Is there even point opening it again? Because if you were generous it paste and made sure it's spread it might be waste of time.
