Question Ryzen 9 7950X temp out of control ?

[tomafantomas]

Hi, one month ago I bought a new AIO, a Lian LI Galahad II LCD and I was happy with the performance, I was hitting 85c in cinebench with 220w and 5.3ghz all core with a 25 negative offset undervolt

Fast-forward to a few days ago, I started having random restarts, jus sitting on desktop, or random games crashing

So i just thought that the undervolt somehow got unstable and changed it to 20 negative offset and to be sure it is stable I started testing the cpu and to my surprise, I've seen a huge temp increase and huge performance decrease, hitting 95c instantly at 180w and 4,9ghz all core

Things I tried:

• Remounting the AIO (and somehow I managed to strip 2 mounting screws on only one thermal paste change)
• Resetting and reapplying bios settings
• Downgrading to the last BIOS version
• Reinstalling Windows

Nothing changed between these temp changes, same Windows, same bios settings, same everything, just randomly started losing performance. I don't know where the root of the problem lies, I started a warranty claim on the Lian Li website to try and see if there was any factory problems with the AIO, being a new product

PC SPECS:
CPU: Ryzen 9 7950X
MOBO: Asus STRIX x670E-E
RAM: 32gb 6000mts TridentZ NEO
PSU: 1000w Corsiar RM1000x
GPU: MSI RTX 3080 Gaming TRIO

EDIT: I forgot to mention that I reach 90-91c in games for a few seconds, but that's a 10c increase at least since the last time I checked.

For the sake of reference, what BIOS version are you ion right now? Make and model of the case and it's orientation/mounting in the case?

Remounting the AIO (and somehow I managed to strip 2 mounting screws on only one thermal paste change)
You might want reach out to Lian-Li to get a new mounting kit since you mention the threads being stripped but I suspect the AIO being the issue. Maybe the pump block ended up having cavitation.

I have a Lian Li o11 EVO XL with 10 fans, so no problem on the airflow part, I'll start a RMA process for the AIO
