Hey all, got a question. I recently got some older (3-5 yrs) Dell PCs. One has a dead CPU fan. It is an 80mm (I believe) that connects to a 3 pin header (+, -, temp or speed control) Wire colors are red, black, white. In another Dell, I have the same size fan, but it has 4 wires (+, -, temp, PWM/speed control).
Now I know I don't get the benefit of speed control when using the 4pin fan on the 3 pin header, however, when I plug it in and turn the PC on, the fan spins at it's highest speed. For this configuration, I did not connect the blue wire, which I believe is the speed control. The thing sounds like it's going to take off.
The questions I have are: Is there a way to turn down the speed of the fan? Should I hook up the blue wire instead of the yellow? Should I just spend the $10 and get a 3 pin fan? (was trying to avoid hitting a store.. weather sucks out there). Any other suggestions?
Thanks...
