Two-pack 24 V 120 mm PWM fans

This two-pack supplies a pair of 120 mm by 38 mm case fans that run on 24 V DC and connect via standard 4-pin PWM headers. Each unit uses dual ball bearings rated for up to 100000 hours and includes a metal guard grill plus mounting screws. They are aimed at builders who need high static pressure for radiators, mining rigs or industrial enclosures.

Sustained-load airflow and speed range

Under continuous load the fans spin between 3000 and 5000 RPM, delivering up to 174.9 CFM and 21.8 mm H2O of static pressure. The PWM curve lets the motherboard or a sensor automatically raise speed when component temperatures climb and drop it again when the load eases. This behaviour keeps airflow matched to thermal demand rather than running at a fixed maximum.

Thermals, noise and power draw

At full speed the pair draws 0.8 A each at 24 V and produces 58 to 62 dBA of acoustic noise. The 50 cm cable allows flexible routing inside larger chassis. Dual ball bearings maintain consistent speed and lower friction over long periods, helping the fans sustain their rated airflow without the thermal throttling or bearing wear common in sleeve-bearing designs.

Questions about this item

How loud and hot does each 24 V 12038 fan get when it runs at 5000 RPM all day?

At full speed the pair reaches 58–62 dBA and draws 0.8 A from a 24 V rail; PWM lets the motherboard drop the speed to 3000 RPM when temperatures fall, cutting both noise and power.

What must my system already provide for these two 4-pin PWM fans to spin up?

A 24 V DC header or fan controller that supplies 0.8 A per fan and accepts a standard 4-pin PWM signal; the 50 cm cables plug directly into such headers.

Will the 38 mm thickness and 174.9 CFM airflow fit the older CPU cooler radiator I want to keep?

The 120×120×38 mm frame matches standard 120 mm mounting holes, and the included metal guards and screws let you bolt the fans onto most legacy radiators or shrouds.
