CPU fan wont work?! Asus P2B

[rbownes]

I just bought a Celeron 633 and finally got it to work with my Asus P2B MB (with some help from this forum). The only thing is that the fan (standard Intel fan and hs that came with the cpu) is not working. I plugged it into the 3-pin "CPU FAN" connector and I tried the "PWR FAN" connector too but still no go. My previous cpu was a celeron 300a and the fan on it connected to a standard 4-pin Hard Drive power connector - which worked fine.

Is there a setting in the bios to turn on these power connectors? Or are they just not working?

I had a different fan with my cel-300a which also did not work with the 3-pin MB connector.

Maybe i can wire it into a Hard drive power cord. Any ideas on this? Can i get an adapter to connect this fan to a hard drive power cord? (3-pin to 4-pin power adapter?)

Thanks in advance.

Yea sounds like you Fan header is broken...
I have a friend which had this happen, he just added 12v to one of the
Fan outputs and this intern gave power to the rest of his Fan header...
I DO NOT recomend this cuz when I saw it I thought he was nuts... but it
did work...

Just take the Red and black wires and wire them to the 12v + and - respectively
off the HDD connector and you'll be Fine, you can even leave the Yellow
Monitor lead connected to the Fan Header to get fan monitoring... that
part should still work...

Maybe I'm missing something, but with 4 wire power leads, yellow is 12v, red is 5v, and yes, black is ground.

The RED off the Fan, not the Molex connector... I assumed he knew which
it was, and if he didn't, he really needs to buy an adapter because
he doesn't have enough knowledge to safely make such a mod...
