Solving the high noise problem of Intel P4 CPU fan

Recently I bought an Intel boxed P4 506 + CPU, 2.66 GHz, with an original fan, motherboard: ASUS p5gd1

After assembling the computer and taking it home, I found that the noise was so loud that I could hear it in another room 5-6 meters away that I could not use it to work.

Solution: Enter the motherboard BIOS, hardware monitor, and set the cpu q-fan control from disabled to enalbled.
Let the fan speed automatically adjust according to the CPU temperature, rather than the maximum speed of the CPU fan. When the rotation speed exceeds 3500 rpm, there will be significant air friction.
