Question Fan Wiring Colours on the Antec True Power 750 Blue ?

[nowaste]

Does anyone have a diagram or just know what each wire on 4 pin fan connector does? Like what's positive, negative and does nothing? I can't find it anywhere on the internet.

Welcome to the forums, newocmer!

Red is +ve(as it's the hot side), white would be the -ve(cold side), from my crude understanding of electrical wiring.

My question is, what do you plan to do with a fan from a 13 year old PSU?

How do you know? Have you measured the ripple because that is usually the issue with ancient PSUs.

From another ADDA fan (PWM, brushless)
LEAD WIRES : UL 1061, AWG26 , L = 320 +/- 10 mm
Red = positive ;
Black = negative.
White = FG ;
Blue = PWM

FG->Frequency Generator (aka Tach)

For others who may come along. Working inside a PSU can be VERY dangerous. This is not something a typical user should be doing.

PSA over. Carry on and be careful.
