2019-12-18

The noise problem of the cooling fan is a relatively common problem. Some are the quality of the cooling fan itself, while others are the installation of the cooling fan. Therefore, the correct installation of the cooling fan is also very important 1. The installation method of clamping the cooling fan frame up and down. Due to the vibration of the cooling fan during operation, it is easy to produce resonance and amplify the sound. A high-speed cooling fan without vibration can not be.

1. The installation method of clamping the cooling fan frame up and down. Due to the vibration of the cooling fan during operation, it is easy to produce resonance and amplify the sound. A high-speed cooling fan without vibration can not be.
2. The fan blades are upside down, absorbing heat from the bottom up. Due to the gravity of the fan blade itself, oilCooling fanIt may exceed the height of the outer frame, contact the radiator below and generate noise (it can be solved by replacing the double ball bearings)
3. The locking screw is not installed correctly, the first screw is too hard, the lock is tight, and the parallel second screw is also tight. The two opposing screws are then locked, which will cause the outer frame of the fan to deform and twist, and the fan blades will contact the outer frame wall possibly to create acoustic scratches. The correct way is to lock the first screw and tighten it. Do not deform the lock. Lock the diagonal screws again when finished, and lock the other set of diagonal screws when finished.
