Compact 45 mm blower for notebook CPUs

This 45 by 20 mm square cooler fits tight laptop and projector chassis where axial fans cannot mount. The blower wheel pulls air through the heatsink and exhausts it in a focused stream, making it suitable for small-form-factor CPU cooling. It runs on 12 V and draws only 0.5 W. The unit is new and uses a ball bearing for durable rotation.

Three-pin power connector with speed signal

The 3-wire lead supplies 12 V power, ground and a tachometer output so the system can monitor fan speed. No PWM wire is present, so voltage control is the only way to vary RPM. The connector matches standard notebook headers, allowing a direct swap without adapters. The black, non-LED housing keeps the install discreet.

Maximum speed below 1600 RPM

The spec lists an upper limit of 1600 RPM, which determines the peak airflow and static pressure this blower can deliver. Buyers needing higher flow for overclocked desktop CPUs or multi-core mobile workstations should look elsewhere. For low-TDP notebook processors and projector lamp cooling the rated speed is adequate.

Questions about this item

How long will the ball bearing last before the fan needs replacing?

The ball bearing design is rated for continuous operation at up to 1600 RPM, so replacement is only needed if the bearing wears out or the fan fails.

What stops the fan from spinning faster during heavy load?

The fan speed is capped at 1600 RPM, so it cannot exceed that limit even under sustained thermal demand.

How much heat and noise does the 0.5W motor produce when running all day?

At 0.5W draw and 12V supply the motor generates minimal heat, and the 45×20mm blower stays quiet at its sub-1600 RPM ceiling.
