80 mm 12 V alarm fan

This 80 mm square case fan runs on 12 V DC and draws 0.14 A. It measures 80 x 80 x 25 mm and uses a three-wire connection that includes an alarm signal line. The alarm output lets the system detect a stalled or failed fan before temperatures rise.

Three-wire alarm signal

The third wire carries a tachometer or alarm pulse so the motherboard or a hardware monitor can flag a stopped rotor. Builders who need a simple two-wire fan or a four-wire PWM unit for speed control should choose a different model.

Questions about this item

What does the 0.14 A draw mean for my power supply?

The fan pulls 0.14 A on the 12 V rail, adding a very small load that any standard ATX supply can handle without issue.

What does the three-line alarm signal actually tell the motherboard?

The third wire carries a tachometer or alarm pulse so the board can monitor fan speed and warn if the rotor stops spinning.
