Re: Changing the IBM Power supply fan for the Digikey fan

Thanks David,
I'll do that. Thinking about it later, as long as those 2 wires are not connected to +12V, only one way the fan will work.

Hi David,

The pinout for the existing power supply fan differs from what I
see online.

pin 1 -- Black -- GND

pin 2 -- White -- ?

pin 3 -- Blue -- ?

pin 4 -- Red   -- +12V

Which of the 2 wires are Sensor and Control.

The Digikey fans recommended have Red -- +12V, Black -- GND,
Yellow --
Sensor and Brown -- Control.

How to connect the new fan to the old fan's plug?

73 ... Sid.
