Welcome to the forums, newcomer!
I just got a new system today
Please list the specs to your build like so:

BIOS version for your motherboard at this moment of time.
I am using an AIO Liquid Cooler from Ocypus called the Ocypus Iota l24.
How is the AIO mounted in your chassis/build?
Have you tried undervolting your processor?
