3pin to 2 pin fan connection
I changed a fan in one of our office computers, however the mobo header only has 2 pins, do i need an adapter to fix this or is there an easier solution?
It worked for me. I bought a new fan, took out its wires from the socket with a pocket knife(without cutting the wires, the pins lock inside the socket and they can be unlocked and taken out) and tried connecting them to the PSU pins in combinations of 2...
The fan is spinning with red/black and red/yellow combinations. Connect the red to the + sign or where the red wire of the old PSU is supposed to connect.
It also works if you use both black and yellow to connect the '- ve' pin(where the old fan's black wire was connected).
I think the Red/Black combination has a faster spin rate.
I rearranged the wires and put them back in the socket in the order I wanted and connected them to the PSU pins.
Don't know if doing this will affect the PSU in a bad way. It is working so far, which is 15 minutes.
In the beginning I also tried to plug the socket into the PSU pins and it did not work. That is because the wires are arranged in a way that both the combinations would not work. One because it is the combination of yellow/black and another because red wire is connected to the '-ve'(black wire) pin.
