CPU temp spike

[_BJE_]

I Started to Mine some Ethereum when im not at home because why not. but i resized one thing it doesn't use much CPU but the CPU temp is keep spiking from 45C - 75C and the fan speed ramps up and down. im not sure what is going on but even msi afterburner shows my cpu usage stays around 5-10% and the temp spike

id recommend to stress test your CPU first to find its max temperature (aida FPU test 10minutes, or handbrake H264 2-pass encoding)

your screenshot is reporting 88C with 10% usage. Thats mayo level. Resit heatsink if needed.
