Fans GM0504PEV2-8Lead 40mm case fan 5V 7000 RPM

SKU CH-2BV8-YNPS0 MPN GM0504PEV2-8Lead

A 40 mm magnetic-suspension case fan spinning at 7000 RPM with 5.9 CFM airflow at 32 dBA

  • Magnetic suspension bearing cuts noise to 32 d-BA
  • 5 V operation draws just 0.1 A for low power use
  • 7000 RPM delivers 5.9 CFM airflow in tight spaces
  • 40 mm square frame fits compact builds
  • Weighs only 7.5 g for minimal added mass

SUNON 40 mm magnetic suspension fan

This 40 mm axial fan uses a magnetic suspension bearing and runs on 5 V DC. It draws 0.1 A for 0.4 W and spins at 7000 RPM. The compact 40*40*6 mm frame fits tight spaces in industrial or embedded systems. A three-pin lead provides speed monitoring and control.

Suits space-constrained builds needing quiet airflow

Buyers who need low noise in a shallow chassis will appreciate the 32 dBA rating and magnetic bearing longevity. It delivers 5.9 CFM for targeted component cooling. Builders who require higher static pressure or larger air volume should look at something else.

5.9 CFM airflow with 0.1 Inch-H2O pressure

The fan moves enough air for heat exchangers and small enclosures where depth is limited. At 7.5 g it adds negligible mass. Headroom ends when the thermal load exceeds what 5.9 CFM can remove or when mounting points demand a larger frame.

Questions about this item

Does this 40 mm fan need a 3-pin 5 V header on the motherboard?

Yes, the GM0504PEV2-8Lead uses a 3-pin lead and runs on DC 5 V, so the board must provide a matching 5 V header.

Will the magnetic-suspension bearing and 32 dBA noise level let it sit next to legacy components without vibration issues?

The magnetic suspension bearing eliminates physical contact, keeping vibration low even at 7000 RPM while the 32 dBA rating stays quiet beside older parts.

How can I confirm the fan is delivering its rated 5.9 CFM after installation?

Check that the tachometer signal on the third pin reports 7000 RPM and that airflow matches the 5.9 CFM specification under load.
