I have wired a PC fan to a power supply. The fan is 12 volts and my power supply is 12 volts. The fans says it is 0.32 amps but my power supply is 1.25 amps. Is this going to cause a problem or will it just burn the motor out faster. I dont know much about wiring but I was able to hook it up and it runs ok. I am just worried about fire danger.

bump......

not to jack your thread or anything but how do you wire PC fans? Can you plug them into any outlet or do you have to re-wire them for that?

I'm pretty sure you will be fine. Because the amp usage w/ the fan is less than the power supply you wont overload it or anything. I have some basic information about wiring and electricity but someone more experience might want to confirm that.

Here ya go
DIY Wiring : fans!

Power supplies are rated at max they will deliver.

Fans (and other items that plug into PSUs are rated at what they need)

The PSU has more power the needed. The fan will take what it needs no more. (Unless the PSU is a constant current type, but it ain't)

Think of it this way. The outlet your lamp is plugged into is a 15amp outlet. That light ain't 15 amps.

Its really simple to wire. Just get an old ac adapter that is 12 volts.

Cut the end of it off.
Splice each of the wires.
Then grab your pc fan. Usually 3 wires on it. Yellow, Black, and Red is what mine have been everytime.
Splice up those so you can wire it.
Take that positive and negative black and red wire and connect them to your spliced ac adapter

And viola plug that baby in and let it do its work.

Hope that helps, I can post some pictures if you need a better explaination
