120 mm PWM case fan for radiators

The COUGAR MHP120 is a 120 mm case fan built around a hydraulic bearing and a four-pin PWM connector. Its metallic-reinforced motor hub and shell add structural rigidity while the supplied anti-vibration dampers reduce transmitted resonance. A 100 mm low-noise adaptor and a 300 mm extension cable are included for flexible routing.

Suited to high-static-pressure cooling.

This fan targets radiators and restrictive heatsinks where its 4.24 mm H₂O pressure rating at 2000 RPM matters. Builders who prioritise absolute quiet over airflow density should look elsewhere, as the maximum noise level reaches 41.2 dB(A). Systems without a PWM header cannot use the automatic speed curve.

Sustained output at rated voltage

At 12 VDC and 0.23 A the motor draws 2.76 W while delivering 82.48 CFM across the 600 to 2000 RPM range. The hydraulic bearing maintains consistent torque during prolonged operation and the reinforced hub resists flex under continuous load. Speed stability stays within the stated tolerance without thermal throttling.

Questions about this item

Does the 4-pin PWM connector plug straight into a standard motherboard fan header?

Yes, the 4-pin PWM connector fits any standard motherboard fan header and draws 12 VDC at 0.23 A.

Will the 120 mm frame and 25 mm thickness fit the same mounting holes as my older 120 mm fans?

Yes, the 120 x 120 x 25 mm dimensions match the standard 120 mm mounting pattern used by older fans.

How can I confirm the hydraulic bearing is running within its 600-2000 RPM range after installation?

Check the RPM reading in BIOS or fan-control software; at minimum PWM it should sit near 600 RPM and at maximum PWM near 2000 RPM.
