Tips: Factors affecting the noise of DC cooling fans
1. Speed. The faster the DC fan rotates, the bigger the fan, the louder the noise.
2. Bearings. The bearings of DC fans are briefly divided into two types, one is oil and the other is ball. Under normal circumstances, ball bearing fans are more noisy than bearing bearing fans.
3. Airflow. During the rolling of fan blades, they will encounter resistance in the air. The faster the rolling speed, the larger the blade area and the greater the resistance, so the noise will be greater.
4. Conflicting force. If the fan is used for a long time, the fan will be excessively racked, vibrated, and the center of gravity is unstable. This will cause a collision or conflict between the fan blade and the fan frame, and then generate noise.

Existing reviews of 12V/24V DC Cooling Fan, 40mm x 40mm x 20mm

EXCELLENT value for the money.

I have two DC cooling fans in a mounted in my trunk storage area keeping my amplifier cool. They are on for 6-8 hours a day since I drive alot and they are rock solid! No complaints at all.

Works as expected

I decided to replace the old fans with some DC cooling fans. This is not a bad purchase for the price. Compared with my old radiator fan, it is quieter.

Great little cooling fan

This is actually more quieter than my old cooling fan and the air flow is awesome. If anyone looking for a fan, then this is your replacement fan. The quality is very well and the price is very fair.
