3 pin connector/fan

Recommended Posts

Could someone please tell me why my psu has what looks to be a fan connector as one

of the permanent wires coming out of it . It looks like it should be plugged into the motherboard.

Here is a link showing the wire. http://www.newegg.com/Product/ImageGallery...0Power%20Supply

According to this review. It's to monitor the 135mm fan

So can I plug it in any were on the m/b ?

I thought that the m/b plugs all had power.

Look at that wire, it is only using 2 of the 3 pins.

 

So its using PWM and negative, just plug it into a SYS_FAN header and then you can control the PSU fan speed via the bios or let it be thermally controlled by the bios.

I don't think you'll be able to control the fan speed that could be a little risky and better left to the power supply. It's provided so you can monitor the power supply fan speed via the motherboard bios and issue an alarm or shut down the PC should it fail.

 

Cheers

You plug it into one of your motherboard fan connectors and you can monitor the speed of the psu fan.
