Dead H80?


Recommended Posts

Hi guys - just setup a new system with an i7 3820 and decided to go for the H80.


I believe I've connected everything properly, the PC boots up and all the case fans start (which are all connected to molex plugs). The problem is the H80. There's no LED and the fans don't spin at all. My mobo instantly complains about a lack of CPU fan and CPU overheat and after quite a short time just switches off (presumably CPU thermal shutdown).


I've got the molex connected AND the CPU fan to the correct header.


Tried the firmware reset trick but either I did it wrong or the H80 is duff.


Any ideas?
