Question CPU starts overheating as soon as I boot my PC ?

[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.
AIO cooler pump has to be running at full speed all the time.
Do not connect AIO pump to regulated fan headers.

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

I’ve updated to latest bios and I’ve connected the headers to the correct spot, no protective film either. Everything else is fine I’ve changed and replaced almost every part but the cpu. Nothing seems to work.

I’ve updated to latest bios

also be sure to reset BIOS defaults after each update.

Everything is at default

Everything is at default

defaults from before an update may not be the same as after.
especially in these situations where Intel is altering features to help with all of the issues surrounding these last 2 generations.

In this case, what can I do?

To manually reset bios to defaults .
Enter BIOS
Press F5. Load bios defaults.
At pop up click yes or ok.
Press F10. Save and exit.
Click yes or ok to reboot with Bios defaults enabled.
After reboot enter bios and set XMP for memory.
F10. yes or ok and reboot to windows.
Now you are running Bios defaults and not pre overclock settings from the board maker with the new bios installed.
The original bios files until the last few have had overclocked /unlimited amperage available to them as bios "defaults, with a goof on intels part not to enforce Intel "specs" with voltage and amperage settings available to the processor.

I e done this already, still overheating
