I built a new i7 system on a 400R 2600K with H80 cooler today. All H80 pump / fan found dead. No light in the button lights and the fans. I tried using the header SYS_FAN1 and even tried the molex connector. No dice. I enter the BIOS and see the temperature of the CPU one place.
This may or may not be related, but the new system only intermittently until the boots, but when it does I've only been in the BIOS to check things out for a short period before closing. One of my hypotheses is that you cannot have a sufficient energy supply. I'll know tomorrow when I try TX650M. Currently, I have the TX550M and thought it was underpowered for my system configuration. If you have solved the intermittent starting problem to H80 and still does not work, I will assume the H80 is dead.
My guess is that I have second defective parts, including CPU MB and worse. In which case H80 unaffected by any of these defective parts, I will assume the H80 is dead.
