140 mm FDB case fan

The FSP CF14F01 is a 140 mm case fan built with a fluid dynamic bearing for long life and low friction. It spins up to 1600 RPM and delivers 45 to 50 CFM of airflow while producing 20 to 25 dBA of noise. A 4 pin connector enables PWM speed control for automatic or manual tuning.

Suitable for quiet builds

This fan suits builders who want a single 140 mm intake or exhaust with a measured noise floor of 21.5 dBA and no LED lighting. It is not for systems that need multiple fans from one header, RGB synchronisation, or higher static pressure for dense radiators.

140 mm frame with 4 pin PWM

The 140 x 140 x 25 mm frame fits standard 140 mm mounting points and the included 4 pin Molex adapter lets you run the fan from a peripheral power plug if a motherboard header is unavailable. Nine curved blades and the fluid dynamic bearing keep airflow steady across the speed range.

Questions about this item

How long will the fluid dynamic bearing in the 140 mm fan last before it needs replacing?

The fluid dynamic bearing is designed for continuous operation without a scheduled replacement interval; typical service life exceeds several years of all-day use.

What limits the CF14F01 when it runs at full speed for long periods?

At 1600 RPM the fan moves 45-50 CFM while staying at 20-25 dBA, so acoustic output is the first constraint you reach under sustained load.

How much noise and heat does the 140 mm fan add when it runs all day?

It produces 20-25 dBA at full speed with a typical 21.5 dBA reading, and its 4-pin PWM control lets the system lower speed to cut noise further.
