120mm PWM fan for CPU coolers

This 120mm square fan connects via a standard 4-pin PWM header and runs on 12V at 1.05A. It is built with a ball bearing for continuous operation inside a chassis or mounted on a heatsink. The black frame suits low-profile builds.

Thermals noise and power draw

PWM control lets the motherboard adjust speed to match thermal load so the fan only draws the current it needs. Ball-bearing construction keeps acoustic output steady over time without the rattle that sleeve bearings can develop. The 12V 1.05A rating defines its maximum electrical draw.

4-wire PWM connector decides fit

The 4-pin connector is the single specification that determines whether this fan works with your header; 3-pin headers will run it at full speed without speed reporting. Buyers who need a 3-pin only fan or a 5V ARGB header should look elsewhere.

Questions sur cet article

How do I mount the DS12025B12U fan onto a 120mm heatsink and which step is often missed?

Align the four corner holes with the heatsink brackets, secure each screw diagonally, then plug the 4-pin PWM connector into the CPU fan header so the motherboard can control speed.

What maintenance will the ball-bearing fan need over its life?

The ball bearing is sealed and requires no lubrication; periodically blow dust from the blades and frame with compressed air to keep airflow at spec.

What limit appears first when the fan runs at full PWM duty for long periods?

At maximum 12V 1.05A input the motor draws its rated current, so the 4-wire PWM circuit and ball bearing become the limiting factors for sustained operation.
