Manufacturer description
The Wathai 120mm x 120mm x 38mm industrial cooling fan is built for the jobs a standard case fan cannot handle. Running on 12V at 0.5A, it spins at 3000 RPM and moves 125 CFM through its 38mm-thick frame, which is why it turns up in retro PC builds, tool chests, AV cabinets, caravans, and equipment enclosures where hot air needs to be pushed out fast. The dual ball bearing design is rated for 50,000 hours, so it holds up in the continuous-duty and higher-temperature environments that sleeve bearings tend to fail in. The package includes a fan grill plus mounting screws and nuts, so you can…

Frequently Asked Questions
How much air does this fan actually move?
It is rated at 125 CFM at 3000 RPM, drawing 0.5A on a 12V supply. That is several times the airflow of a typical low-speed 120mm case fan.
Will this plug into my motherboard fan header?
Not directly. It terminates in an XH2.54 2-pin connector on a 25cm cable, so it is designed for a 12V DC supply or fan controller. You will need an adapter for a 3-pin or 4-pin header.
Can I control the speed or will it always run at 3000 RPM?
It is a 2-pin fan with no PWM or tachometer wire, so it runs at full 3000 RPM on 12V. Speed control requires an external voltage controller on the 12V line.
How loud is it?
The rated noise level is 42 dBA. It is meant for industrial enclosures, caravans, and equipment cabinets rather than a quiet desktop next to your head.
Will it fit a standard 120mm fan mount?
The screw pattern is standard 120mm, but the frame is 38mm thick instead of the usual 25mm, measuring 120 x 120 x 38mm (4.72 x 4.72 x 1.5 in). Check depth clearance before ordering.
