Question Overheating 2080 Ti FE ?

[MongooseMonke]

Specs
MOBO: Gigabyte B450M DS3H
CPU: Ryzen 7 5700X
GPU: RTX 2080 Ti Founders Edition
RAM: G. Skill Aegis 16 3200Mhz cl 16
CPU cooler: ThermalTake Pearless Assassin 120mm
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 at the top and one at 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

Download and install MSI Afterburner and set a custom fan curve. Set it quite aggressive like 100% when the temp reach 75c and see if it helps. It's also important to make sure you evacuate enough hot air from the case when the GPU is running. How are you controlling your case fans?

Also, your PSU is way too weak for your system. You should have at least 650 W, ideally 750 W.

The 2080Ti should have a 850W minimum PSU if not a 1000w. If you're get the newer ATX 3.1 PSU an 850W will be fine. Im really surprised that card has not tripped out the PSU yet with the high transit spikes they have.

First, pull the card back apart and check the thermal paste. Look at the pattern on the die and heat block, it should be nice thin and uniform. If the thermal paste looks thick then you put to tall of thermal pads on and the heat block is not making good contact with the GPU die

Minimum 850 W? The official minimum PSU recommendation for this card is 650 W. It's a 250 W TDP card. Saying that you need at least 850 W for that is quite awkward.

I had, brother now has, an EVGA 2080 Ti FTW3 ultra gaming on a EVGA G2 750W psu and would trip the rail and reboot the computer. I upgraded it to a EVGA 850W G2 which still had issues, finally pulled my 1600W G2 from a server build. This was a known issue that Jayztwocents, Gamer Nexus, and LTT all covered back when these cards came out, and were recommending 850W minimum 1000w to be safe. There is now the ATX3.0/3.1 standard that handles the spikes way better then ATX 2.x units did which if you get one of those you could drop to a 850W or chance a 750W. The card is "rated" at 250W but pull closer to 300W and with transit spikes for very brief moment can pull up to 600w.

A quick google search pulls up Steves video explaining the spikes, started around the high end Nvidia 2000 series and AMD 6000 series.
