Hey,
Thanks for your reply. I solved the issue by removing the pump from my AIO. I noticed that the thermal paste pattern was very small, which made me think there wasn’t good contact between the AIO plate and the CPU. So, I cleaned everything up, reapplied thermal paste, tightened the screws better, and now I’m at 35-45 degrees in idle and a maximum of 75 under load.
(The AIO is set to exhaust, the rear fan as well, while the three side and bottom fans are set to intake.)
I still want to thank you for your quick response and your willingness to help.
PS: Here’s a photo of the build.
