2 wire vs 3 wire CPU fans, does it matter?
Hi,
Stan, my brother-in-law just phone to ask about replacing the noisy cpu fan in his amd system. He bought a new fan for $10 and said it has 3 wires on it. The one in the system has 2 wires on it. He asked me, the family computer whiz, if it was OK to plug it in. hmmm.... "Ya got me there, Stan old boy, but I'll find out for you," hence this post. Anybody know what's going on with the 3rd wire? Thanks |

But as he didn't have speed monitoring before he won't see any difference. HTH SteveH |

The third wire is used to transmit the RPM speed of the fan to the
motherboard, if you have a monitoring utility. -- DaveW "-Alby Hewlet" wrote in message ... Hi, Stan, my brother-in-law just phone to ask about replacing the noisy cpu fan in his amd system.
