I installed a Zalman CNPS9500A-LED this afternoon which involved stripping down the mobo to get the backplate on (I know I should have bought it BEFORE the build.. ) it was time consuming to say the least.. then I powered up and... nothing, no POST.. NOTHING  :(

Now my mobo has a 4 pin CPU fan connector, the Zalman has a 3 pin. I followed the instructions, connected the fanmate speed controller to the mobo, and the cooler fan to the fanmate. After a bit of head scratching (and adjusting the fanmate between full/half/minimum) I decided to unplug the fanmate and plug the fan direct to the mobo. It worked straight away, booted no probs.
Has anyone got any idea why this happened? I'm not that bothered about controlling the fan speed anyway but wondered why. Maybe my controller is knackered?

:-?

You must have the fan plugged in or the mobo will refuse to boot... it must sense a fan is in place... part of the safety features in BIOS

Possibly their controller is wired a bit off?  Not sure

Look at the colors.. I think they are RED BLUE (possibly yellow) and BLACK

I am thinking there may be a WHITE in there but dont remember for sure...

RED is +  Black is -   and the third color is the sensor... make sure this matches the pins on the motherboard..


NOw, the 4 pin is NOT the same as the 3 pin.. in that as I recall you CANT change the fan speed because the sensor is based on PULSE not a strait signal... but, the pins for the mate should work with 3 of the pins from the 4-pin on the motherboard.. I jsut do not have time to look up the wiring or I would for you but as I recall even if you get the mate plugged in right and working it all a manual speed change.. you wont have any automatic control

Thanks Nick, it's running fine without the fanmate, so I'll leave it as is.

I have an E6750 OC to 3.2Ghz, (400 FSB x at a FSB : DRAM ratio of 1:1 and after 2 hours of stress testing with Everest it never went above 52C, idles at 34-36C, so I'm happy with that. Hopefully when the thermal compound "beds in" it may go lower.

Cheers again.
