I have an APC 1600VA UPS (BVX1600LI), which has enough power for my PC but has a very annoying problem.
It has a very loud fan which kicks in if the load is above ~250 watts, which means it is always on when I have to play any games on the PC. It is simply intolerable for me. I wanted to replace the fan with something quieter.
This is the information that I have gathered so far about this fan:

This is the information that I have gathered so far about this fan:
- The fan model is DA06025S12MF (Yimeng brand apparently).
- There are 3 cables on a JST XH connector - red, yellow, and black.
- When the fan is running, the voltage b/w Red and black is 11.96V (it is a 12V fan), and the voltage between Yellow and black is 2.64V.
- If I stop the fan manually, the voltage between the Yellow and black is 4.98V. This looks a locked rotor signal.
