Sunon KD1208PTB3-6 80mm 12V Fan

The Sunon KD1208PTB3-6 is an 80mm square cooling fan measuring 80 by 80 by 25 millimetres. It operates on 12 volts DC with a rated power draw of 1.4 watts. A four-pin power connector with a 12-inch two-wire lead supplies the electrical connection. This unit suits DIY cooling projects requiring a compact axial fan.

Sustained operation at 2500 RPM

At the rated 2500 RPM the fan produces an acoustic level of 28 dB(A). The 1.4 watt power figure represents continuous electrical input rather than a brief startup peak. Builders needing lower noise or higher static pressure at this form factor should evaluate alternative models.

Questions about this item

How loud is the 28 dB noise level when the fan runs continuously at 2500 RPM?

At 28 dB(A) the fan produces a quiet hum comparable to a library whisper, so it remains unobtrusive during all-day operation.

My motherboard only has a 3-pin header; can I still power this 4-pin Sunon KD1208PTB3-6?

Yes, the 4-pin connector fits a 3-pin header; the fourth pin simply stays unused while the fan receives 12 V from the two power wires.
