Stupid fan wiring...

[Myka]

So I bought this super cool computer fan that's clear with blue LEDs thinking it will look sweet in my stand and would be easy to find an AC adapter power supply to plug into a wall outlet. Well, I was wrong (first time ever ), or at least I think I was wrong because I can't figure this thing out. I figure a 3-pin atx to a powersupply is easy...ohhh nooooo.

Wth do I have to do to make this work? Can I go 3-pin atx to usb to ac adapter power supply? I need 12V 1400 mA.

This is assuming your fan came with a 3 to 4 pin molex connector.

The second picture shows the power supply with a 4 pin molex. This is what I used for my fan in the stand. The LED's on the fan went kaput about 2 months after install, lol.

Yeah, the LEDs aren't waterproof, so I'm thinking they might not last long. I was also thinking that I could probably put a dab of silicone on them to help longevity.

My fan came with a 3-pin apx to 4-pin Molex connector, but if I use the 4-pin only 2 of the wires go into it and then there is another 3-pin separate with the third wire in it. Does that make sense or do you need a pic?

I did see the Cooler Guys apx power supply, but it's like $60! I don't think any of the ones in the linked page will work though.

If you want to run your fan simply a plug and play switch or a timer on/off why not get a cheap converter and have it wired directly to your - and + ends of the fan,..voila.
I have mine similar on a timer running of a AC/DC converter for the last 2 years with no issues.
You need something like the link below.

I soldered mine directly as long as you can figure out witch end is your - and + as the 3rd wire from the fan is really not needed
