Noticed the fans and radiator were gathering dust so I stripped the PC and cleaned all, I decided to take the cooler off and re-seat the CPU/replace thermal paste etc as it was built back in 2018. When I fired it up the cooler was making a noise like a cable touching a fan blade, I assumed it was an air bubble so moved the PC around and it stopped (no issues in the past). Then I noticed the main fans on the radiator were at full tilt and not slowing even the the PC was at idle, checked HWinfo and the CPU was at 73 degrees. Maybe I haven't seated the cooler correctly but it seems strange that immediately after getting air bubbles I'm having cooling problems, just wanted to confirm (as dumb as it sounds) that there's no way to bleed a closed water cooler? There's no evidence of leaks anywhere FWIW.
