  • Maglev bearing cuts friction for quieter operation
  • 32 dBA noise level keeps builds whisper-quiet
  • 8500 RPM delivers strong airflow in tight spaces
  • 5 CFM moves air efficiently through heat exchangers
  • 5 V to 13.8 V range fits varied 12 V systems

Compact 40×40×10 mm case fan

This 4010-size axial fan fits tight spaces on motherboards and small-form-factor chassis. It targets builders who need directed airflow for chipset heatsinks or VRM zones. Buyers who want high-volume case circulation should choose larger fans instead.

Maglev bearing and 12 V operation

The maglev motor runs on 4.5–13.8 V and draws 0.15 A at 12 V for 1.1 W. Rated speed is 8 500 rpm delivering 9.5 CFM at 32 dBA noise. The wide voltage range lets the same unit serve 5 V and 12 V headers without adapters.

Original SUNON KDE1204PFV1 unit only

The package contains the single 4010 fan with its attached lead. No mounting screws, splitter cables or fan-controller software are included. Installers must supply their own fasteners and PWM or voltage control source.

Questions about this item

How much air does the 9.5 CFM rating actually move inside a tight chassis?

The fan delivers 9.5 CFM at 8500 rpm, providing focused airflow across northbridge or southbridge heatsinks in compact builds.

What does the 4.5 V to 13.8 V range mean for motherboard header control?

It operates from 4.5 V up to 13.8 V, so a standard 12 V header runs it at full speed while lower voltages reduce rpm and noise.

Will the 40×40×10 mm frame clear low-profile heatsinks?

The 40 mm square by 10 mm thick frame fits the standard 4010 mounting holes used on many chipset coolers.
