Extremely odd with the AIO and mainboard issue.
Extremely odd with the AIO and mainboard issue.
Hey everyone. I'm facing a strange issue with my AIO and motherboard setup. I have a 5800X paired with an MSI Gaming Plus Max B450 ATX board and a Corsair H60 AIO. It performs well at idle, keeping temps between 30 to 40°C. I decided to upgrade to a M.2 B550MK ATX motherboard. Initially, the setup worked fine, but now the CPU gets really hot—starting around 50-60°C and climbing up to nearly 80°C even when fans and pump are at full speed. I've checked everything, but it seems to function perfectly on the ATX board but not on the M.2 one. I also changed the cable connections, swapping the fan headers and tach cables, but the problem persists. Any advice would be greatly appreciated. Thanks!
Did the CPU get boosted to higher speeds? Your 3600 was quite hot, so I had to lower its frequency to avoid overheating. It’s strange what you’re doing with multiple reader tools—like using HWMonitor—are you certain the temperature readings are correct? If you have a Corsair Commander Core or something similar, testing it might help confirm the issue.
The info suggests the BIOS is correctly reporting 3800 Mhz (3.8ghz). You're working entirely through the BIOS since SSD and Windows aren't installed yet due to temperature concerns. The readings seem consistent despite slow increases, which is unusual for faulty sensors. Since similar cases online show stable readings when issues occur, it might be normal behavior. You're uncertain about next steps—returning the case or motherboard might be an option, but switching to ATX could work too, though it may not be ideal.
You're sure the AIO was secured securely and in contact with the CPU? Have you also refreshed the thermal paste prior to installation? Did you connect the pump power to the CPU fan header?
You're pretty confident about the setup, having adjusted it thoroughly and reapplying thermal paste multiple times. The pump seems to be functioning correctly based on your experience. Since the overheating issue persists despite these changes, it might be related to the motherboard's internal components or firmware rather than the cables or connections you've made.
You're experiencing issues after connecting everything at maximum RPM, with the system idling at 60% in BIOS. It might be worth checking if the sensor readings are accurate. Since you haven't downloaded Windows yet due to temperature concerns, consider downloading it now and testing with another software if needed.
