CPU overheating after moving?

[Sykemo]

Hello, 

So I’ve built my pc more than 2 years ago, and everything has been good since then until 2 days ago. I have moved to a new house and while moving my PC in the car it stayed for around 4-5 hours in the car in a freezing temperature (around -7 Celsius). Now when I turn on the PC, the CPU keeps over heating. It turned itself off 2 times after the CPU temp reached 113C while gaming. And it's reaching 100C while idle. It takes around 20 min   to reach those temps. Not right away. 

 

I wonder if leaving it in the freezing temps caused this to happen. Since Im not sure what else could it be. And what could have gone wrong? 

All fans are still working and the AIO rpm is around 3300 in the bios. 

Could be that the AIO died somehow in the cold? Even though rpm is working? Or thermal paste froze? 

 

AIO is Lian Li Galahad 360

CPU is ryzen 5 5600x

given that it has been moved/transported I would remove cpu cooling block and reapply...I very much doubt the cold has impacted any part of the system, however the only thing I could think might potentially happen is the water/liquid freezing, which may have caused all sorts of issues?

It could be that the AIO froze or killed the pump. It should have antifreeze/glycol, but it's not out of the realm. I'd try an air cooler and see if it works fine.

Try reseating the CPU block with new thermal paste. Try to make sure your pump is working and also try to get rid of potential bubbles that may have occurred.

How do I make sure that the pump is working? It shows rpm of 3300 in the bios. How else would I check it? Also how do I get rid of potential bubbles?

These are just about all you can do. An AIO is not something you could open up and repair on your own. If what you find in these links doesn't help make it work then send it back for warranty if it has any left.
