80 mm ball-bearing CPU fan

This 80 mm fan fits standard CPU cooler mounts and draws 0.28 A at 5 V through a 2-pin connector. The dual ball bearing design reduces wear in continuous operation. No LED lighting is included so the unit stays visually neutral inside any chassis.

Builders replacing an 80 mm cooler fan

The 2-pin power connector suits motherboards or fan controllers that provide basic voltage control without PWM signalling. Systems that require a 3-pin or 4-pin header for speed reporting or automatic curves cannot use this unit directly. Buyers who need variable speed feedback should look at a different connector type.

5 V 0.28 A power specification

The fan operates at 5 V and draws 0.28 A, so the header or controller must supply at least that current at the rated voltage. Exceeding the voltage or using a supply that cannot deliver the required amperage will prevent the fan from starting or cause unstable rotation. Match the power source to these exact figures before installation.

Questions about this item

What 5 V header with a two-pin connector must the motherboard provide for the RDM8025B?

The motherboard needs a standard 5 V two-pin fan header to supply the .28 A current this 80 mm ball-bearing cooler draws.

Will the two-pin RDM8025B run at full speed on an older board that only offers three-pin headers?

Yes — the two-pin plug fits a three-pin header and the fan will spin at its fixed 5 V speed, but the board cannot monitor its RPM.

How can I confirm the RDM8025B is spinning correctly after installation?

Visually check that the 80 mm blades turn smoothly and listen for the quiet ball-bearing operation; the two-pin design gives no RPM signal to software.
