An overheating 2080 and second hand woes

hwg315

So I bought a second hand mini ITX pc with an RTX 2080 that's been regularly hitting worrying temps. When I first got it, hot spot temp would rocket to 107º under any gaming load and it would cut power (all info according to HWInfo). I did a repaste (which it sorely needed, the thermal paste was cake), but it is still hitting 100º on the hot spot even with a 70% power limit and some under-volting via MSI Afterburner. Is there anything else I can do or am I SOL? GPU performs fine for overwatch, but I'd like a bit more performance for Doom Eternal, Halo Infinite, etc. Attached is a screenshot of HWInfo during a FurMark run.

Do you have good case airflow? And what cpu and cooler are you using?

 

That seems quite high, especially for that fan speed

System specs:

 

 

CPU: Ryzen 7 7800X3D [-30 PBO all core]

GPU: Sapphire AMD Radeon RX 7800 XT NITRO+ [1050mV, 2.8GHz core, 2.6Ghz mem]

Motherboard: MSI MAG B650 TOMAHAWK WIFI

RAM: G.Skill Trident Z5 NEO RGB 32GB 6000MHz CL32 DDR5

Storage: 2TB SN850X, 1TB SN850 w/ heatsink, 500GB P5 Plus (OS Storage)

Case: 5000D AIRFLOW

Cooler: Thermalright Frost Commander 140

PSU: Corsair RM850e

Almost certain it’s not an airflow issue, but to answer your question it’s a cougar mini itx QBX case and I have an 8700k with a corsair 120mm AIO. I could try a test with the side panel off, but I doubt it would change anything. GPU should be drawing air direct from the outside through the bottom of the case as configured.

I mean, its worth a try i guess? could rule out a few things hopefully

Running with no side panel didn't help with anything. Pinned at 100 degrees between 65 and 70 percent power in Overwatch. At this point, I'm at a loss for what to do.
