Hello!
I just baught a new case fan, as I didn't have an exhaust. But It's only running at 700-750 rpm, which to me (I'm no expert) sounds far too low, and it feels incredibly weak when I hold my hand infront of it. I think I may know the cause of the problerm, but no idea of how to fix it, so perhaps one of you fine gents can tell me.
My motherboard is an ASUS M5A78L-M. Looking at my motherboard diagram, it only has 2 visible fan connectors - a 4-pin 'CPU_Fan' and a 3-pin 'CHA_Fan'. The fan I baught was an Arctic Cooling F12 PWM 120mm. The fan came with a 3-pin power plug, with just a yellow wire running to it, connected to a 4-pin PWM socket adapter, from which was the 4-pin PWM plug.
Seeing as my motherboard only had one 4-pin socket, I unplugged it, plugged to case fan in, then removed the 3-pin power plug from the 4-pin PWM socket, in place for the CPU fan, THEN connected the 3-pin power plug into the 3-pin 'CHA_Fan' socket.
The CPU fan (which is running off the same socket as the chassis fan) is running fine at about 2200 rpm, so does anybody know what the deal is?
Any help is much appreciated!
