80 mm 4-pin axial fan

This 80 mm axial fan uses a dual ball bearing and a 12 V, 0.58 A motor with a four-wire PWM connector. It is sold as a fan-only unit without LEDs, intended as a direct replacement for CPU or case cooling slots that accept an 8038-size frame.

Fits standard 80 mm CPU or case mounts

Builders who need a drop-in 80 mm cooler with PWM control will find the four-pin connector and ball-bearing design a match; systems that require a larger frame, a three-pin voltage-controlled header, or an integrated heatsink will not be compatible with this fan-only unit.

Four-wire PWM connector decides fit

The 4-pin PWM header is the single specification that determines whether this fan can be speed-controlled by the motherboard; if the board or controller only offers three-pin voltage control, the fan will run at full speed without regulation.

Questions about this item

What is the first limit reached under sustained load with the 2 ball bearing and 12V .58Amp rating?

The 2 ball bearing design handles continuous rotation at the rated 12V .58Amp current, so bearing wear becomes the limiting factor before electrical limits are reached.

How much noise and heat does the 80mm axial fan produce when running all day at 12V .58Amp?

The 8038 frame size and axial blade layout move air steadily at the rated 12V .58Amp, generating typical operational noise and minimal heat from the motor itself.

Which 4 pin header must my motherboard already have for this H80E12MS1B7-57A02 to function?

A standard 4 pin PWM header supplying 12V is required; the fan's 4 wire connector plugs directly into that header for power and speed control.
