How to power a 5v Chipset Fan?

by RobertRaspperry / November 20, 2011 6:17 AM PST

I have a 5v Chipset fan, 40mm out of a Toshiba Satellite. It has a Red, Blue, and Yellow wire. I was wondering how I would go about powering that fan so I can make a cooling pad out of it.

Yellow Tach signal.

You only need the red and blue.

I can't know what 5 Volt power you have available. You could recycle some extra wall wart or get another.

Then you may not be ready to build your own cooler.

Since you don't know what a power supply is, then you may want to buy a cooler.

Said cable needs power.

Cables don't supply power, they can transfer it so it may be something or a part of the kit.

But you still need a power supply. The common wall power supply AKA wall wart is something those that build things may have spares or extras we can re-cycle or re-purpose.

and find a power lead that supplies 5 VDC. The Molex power leads from the power supply and the USB ports provide 12 VDC. But certain leads from the power supply do indeed provide 5 VDC. It's up to you to find them. The colors described by Bob are correct.

And no, you cannot assume any specific voltage from any specific color wire from the power supply.

Radio Shack or similar place will have external power supplies that will furnish 5 VDC. I'll let you look.

As explained to you, if you have access to a "AC wall power adapter" one that is 5V or 6V(most likely), you have power. Sometimes called a "power wart" it's one that many electronic devices get power from. The only other possible source would be a USB port. You need a USB plug, some old device, strip it and use the 5v and grd. leads. if you have to buy an AC adapter, that maybe 1/2 of the cost of a new laptop cooler.
