Phanteks M25-140 Gen2 140mm PWM Fan

The Phanteks M25-140 Gen2 is a 140mm case fan with a 25mm thickness designed for high-performance cooling. It uses a hydraulic bearing and a PWM 4-pin connector to deliver speeds between 350 and 1800 RPM. The single black fan suits builders who want strong airflow for radiators or heat sinks without added lighting.

Daisy-chain frame and screw covers simplify

The Unified Fan Frame lets multiple fans interlock physically and share a single PWM signal, reducing cable clutter inside the chassis. A 500mm PWM extension cable is included for flexible routing. Four corner and two bridge screw covers hide mounting hardware for a cleaner visual finish.

Suits radiator and heatsink builds needing

This model works well for users who want to chain several fans under one header and value a tidy appearance. It is not for buyers who want addressable RGB lighting, as this version has no LEDs. It also lacks a dedicated fan controller in the box, so systems without PWM headers or software control cannot adjust speeds automatically.

Questions about this item

How often will the hydraulic bearing need service or replacement?

The hydraulic bearing is sealed for the life of the fan and requires no scheduled maintenance or lubrication.

What limits continuous operation at the maximum 1800 RPM?

At 1800 RPM the fan reaches its peak 101.78 CFM airflow and 36.4 dBA noise rating; sustained loads are limited by thermal and acoustic thresholds.

How much noise and heat does the fan add when running all day at full speed?

At full 1800 RPM the fan produces up to 36.4 dBA and moves 101.78 CFM; power draw stays within the standard PWM 4-pin header limits.
