New AIO Cooler Now PC Random Reboots

[benjaminmill]

I just installed a new Corsair H100i v2 on an old I7-980x on anAsus P6X58D motherboard. The PC keeps randomly rebooting. It keeps randomly rebooting. It’s definitely some sort of hardware issue. It will work fine for awhile. I ran stress tests, did some video conversion etc. No problems, no heat issues at all, then it will just shut down out of the blue then keep trying to reboot about 2-3 times until it is finally successful.
Sometimes I get a message from the BIOS “system overclocking failed press F1 to load settings” or something along those lines. I’m just not certain what it can be? When I pulled out the motherboard to install the aio cooler I cleaned the CPU, checked connections etc. I did not reseat the RAM. The PSU is a Corsair RM1000 only about 3 years old, doesn’t seem to be the issue. Any ideas?

Wanted to add the RAM is running in XMP and has been for the last 8 years with no problems. Random non-software related crashes never happened prior to this cooler install. But then again I’ve neve completely pulled out the motherboard since the initial build until now. I’ve run logs in HW Monitor.

Did you re-seat the cpu or just clean it? Check the pressure of the cooler on the socket. Too tight or too loose can do that.

I didn’t reseat the CPU. I just cleaned it. I also wanted to mention when I push the start button it usually takes about 3 times of attempting to reboot before it starts. I am also using the original Intel back plate that came with the original Intel fan cooler. I couldn’t get the Intel back plate off. It seemed to have glued itself on there. It’s the same thickness etc as the backplate that came with the Corsair cooler. I read some where that trying to force it off could damage the motherboard so I left it alone.

I’ll try loosening the the stand off screws on the cooler. See if that helps. Also the pump sounds strange compared H150i I have mounted on a different PC. The H150i makes no noise where as the H100i v2 chirps and makes other strange noises, but seems fine otherwise.
