Ryzen 3700x + Corsair H100i Platinum = 95’C

I installed the CPU and AIO last night onto an Asrock Taichi x570.

Idle temps were around 40’C.

I then ran a Prime 95 Blended test and within about 20 minutes the temperature hit 95’C.

I’ve removed the AIO block. There appears to be good contact between the CPU and block. There is a nice square of thermal paste on the block and CPU.

Why did I get such crazy temperatures?

I was set to balanced then I changed it to extreme as the temperature increased.

Clearly not.

I’ve just got and and started the PC.

Ryzen Master is showing the vCore at 1.48v hitting 1.5v.

Why is it doing that!!!!

I’ve disabled it and it now hits 1.5v. vCore.

what temp does it hit on normal day to day uses rather than an unrealistic test? Dial in some -ve offset voltage and forget about prime95

Everything is back together now, sides on, under my desk and it is idling anywhere between 35'c - 45'c

I think so.

The voltage thingy me jig is explain by the link about.

Load temps in Cinebench are 75'c top.

Well, I thought all was well until last night.

I was playing Battlefield V and with 10 mins temps were hitting 95'c and the PC blue screened and rebooted.
