I altered a fan on one of our office computers, but the motherboard header only has two pins. Should I use an adapter or is there a simpler way to resolve this issue?

Red/black/yellow on the new fan? Confirm the red and black are connected, or check newegg for direct PSU connections.

The 3 Pin fan should be installed on the 2 Pin, ensuring the holes and pins align correctly and identifying the appropriate contacts for the fan to operate.

this was what i expected to happen, but it refused to turn regardless of the direction. The fan has black, red, and blue cables attached.

Red and black serve as power and ground, blue acts as the pwm signal, indicating the motor's speed to the board.

Regardless of the combination you attempt, the Red will consistently link to a pin header when positioned centrally. You should initially test the Black and red settings to verify header connection before proceeding.

It functioned for me. I purchased a new fan, removed its wires from the socket using a pocket knife (without cutting them, as the pins remain locked inside), and attempted to connect them to the PSU pins in pairs of two.
The fan spins with red/black and red/yellow patterns. Connect the red to the + sign or where the old PSU wire was supposed to go.
It also works if you use both black and yellow for the negative pin (where the old fan's black wire was connected).
I believe the red/black setup spins faster.
I rearranged the wires and reinserted them in the socket in the desired order, connecting them to the PSU pins.
I’m unsure if this will affect the PSU negatively. It’s been working for about 15 minutes so far.
At first, I also tried plugging the socket directly into the PSU pins, but that didn’t work because the wiring arrangement prevented both combinations from functioning. One reason was yellow/black, and another was the red wire connected to the negative pin (black).
