I've just put together a computer and everything seems to be fine, however when i come to turning it on, the processor fan spins, then stops. The computer continues to boot, POST test completes, and the POST screen comes up with all the information, however the processor than has no fan! But the computer does not complain??

The mobo is a Gigabyte GA-8I945P Pro, the processor is and Intel Pentium D 940 dual 3.2ghz. The power supply came with the case and is a 500W so it should be more than enough power. Could anyone please help me, as i dont want to run it without a processor fan unless i know it will kick in when it needs to.

Thanks. Adrian

Seems like you either have a bad fan or maybe there is a special option in the BIOS that does that... Like <30C 0RPM, 31-50C 2000RPM, >51C 6000RPM... etc.... You can always replace the fan on the heatsink and also Pentium 4 will throttle down with its built-in thermal protection as it gets overheated, so I wouldn't worry too much about it even you run it without a heatsink...

Hiya. I've sorted it out now but thanks anyway. Turned out it was a setting in the BIOS and that the new Pentium D's use a different fan controll system, which wasn't set as default in the bios, bios was set to sense it automatically, which it was screwing up. So just to be safe, i plugged the fan into a system fan connection on the mobo, which was fine, went into the bios and had a look around, changed this one setting to what it should be, turned off, connected it back to the CPU power plug, and it worked fine. Weird.

Thanks anyway.
