# Nidec gamma32 4pin pinout

I have Nidec Gamma32 D12F-24BS4 15BH2 blowing fan cooler. It has very strange coloring for wires: red-white-black-yellow.

Probably two of wires are GND and +24v and other two are signal and PWM. What is the correct pinout for this connector type?

Below I attach photo of this connector and photo with comparison to standard 3-pin molex connector.

• Please provide a link to the manufacturer's datasheet for the fan. It's always possible that this fan has a non-standard, proprietary connection. – Elliot Alderson Jun 19 '19 at 17:49
