I have recently gotten an aio for my 7700k in hopes of overclocking, upon startup, the fan speed is at 100% and the cpu reaches 83 degrees. It settles down after, but every few minutes, my cpu usage goes to 50% and the temps go high again. I recently found out that it was chrome that was using most of my cpu, up to 50%. I have no extensions and have scanned chrome using avg. Cooler is corsair h115i v2.
