I recently built a computer for someone. It was just for general use, not gaming or anything, so I went with fairly simple specs. Because they wanted an insanely quiet computer, I went with an NHD15S. The problem is that cooler causes flexing in the motherboard that makes the CPU not make contact with the socket. Is there a not overly janky way that I could fix that without getting a smaller cooler? I know flexing is the issue because it works for a while with the big cooler, but eventually won’t boot after being shut down, or crashes in weird ways and then won’t boot, and the mobo lights always show a CPU and dram light. The box cooler has no issues, but is louder under load.

Edit: it does boot with the large cooler if the system is on it’s side. I followed the mounting instructions carefully.

Edit 2: Solved. I was overtightening.

    Is it mounted correctly? Usually motherboard flex from a cpu cooler is due to tightening things too much or mounting incorrectly in some way like using the wrong mounting hardware or the wrong holes/slots on the mounts.

    Review the manual again and redo installation. The cooler is not properly installed.

    Something else is wrong with your system if an NH-D15 is causing the system to not boot. The flex from the heatsink shouldn’t be perceptible.

    Are you missing a bunch of motherboard standoffs or something? Is your CPU not socketed fully somehow?

    I never knew overtightening was a real issue until it happened to me. I was going to send back my motherboard until I saw someone suggest to loosen the screws of my heatsink.

    That actually worked.
