I've had my h100iv2 installed in a nas/media server for a few years and everything has been running fine. The other day the server lost its network connection. Long story short I started diagnosing and discovered that after turning the server on the CPU temp steadily rises for a couple minutes before the system locks up. I'm not overclocking and the server doesn't move. I suspect the h100iv2 has failed, but I'm just not sure. Does anyone have any advice?
