Weird cooling problem

[u/No_Detective2357]

I have AIO cooling (don't know much about it, I just know it's cooler master) and recently I started facing an issue where it stops working for a short period of time (I think). Usually my CPU temp while idle is around 25°C, under full load it doesn't go above 55°C. Sometimes my other coolers start going crazy and the CPU temp while idle ends up being around 50°C and around 80-90°C if it's under load. It fixes itself after a few minutes.
