So this just started happening today. Recently I purchased new pc components: a asus maximus ix hero motherboard, i7-7700k (4.5GHz) CPU and 8GHz of DDR4 ram. The issue seems to be my cooling. My CPU temperatures are rising from 40C up to over 100C just in BIOS. It has been working appropriately for just over a month with temperatures staying below 60C. I use a corsair H100i v2 for cooling. My only idea is that my PSU is failing me (a Delta 500W).

I'm totally comfused as it's worked fine with me over clocking my CPU to 5GHz. If you have any answers please share.

While a bad PSU is not a good thing, it should have no impact on temperatures.

If your idle temperatures are 40c. there is something wrong with your cooler.
Normally, it should be 10-15c. over ambient.

Most likely your pump could be clogged or failing.

Possibly, you have some sort of restricted airflow feeding cool air into the radiator.

How are your temps. during gaming or benchmarks or just in Windows?

What does the 12V reading say? 12.0- 12.5 is the safe window.

How old is the AIO cooler?
