Question Cou overheating at boot

[Instinct1016]

I just built a new custom pc and I am having cpu overheating issues, I’ve built plenty of pcs in the past and never had this problem and I can’t find a solution to it. As soon as I turn on my pc it immediately goes up to 90 degrees Celsius and will eventually shut off by itself. I have swapped my cpu cooler and motherboard and problem is still there. There is times that i get lucky and my cpu doesn’t over heat but that is after several attempts of trying to boot up my pc and that is rare. When it does happen my cpu stays at 35 degrees which is amazing but i would have to keep my pc on because as soon as i turn it off i would have to keep powering it on and off till i get lucky again.

I’ve also tried different pin slots on the motherboard and nothing seems to work, RPM Is at 2000

Did you updated to latest bios with Intel default profile? And… remember to double check your cooler’s protective film was peeled off

Connect cpu cooler to AIO_PUMP header on motherboard.

Also update BIOS to latest version (that includes microcode 0x12B update), to prevent possible CPU deterioration.
