My fan runs at full speed no matter what. Took it apart to get a better view and make a video. Would replacing the fan do it or is it a faulty sensor on the board?

can also be the heatsink is not seated/held correctly plus using poor quality heat sink paste and can also run at full speed if you have put too much paste on in the first place.
