Hello,  Sid
Only one way will work properly,  so try. 
You have only two different ways.

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.
