cooling fan experiment

lookerup · Apr 15, 2013

I want to try something new. This has nothing to do with PC, but the component's itself. What i want to do is create a board with about 3x - 5x 120mm fans (spare fans) and mount on to a board about 2.5 - 3 ft. The idea is a cheap cooling fans from used fans to circulate my bedroom ( room is pretty small).
how would i make the battery pack and switch?

I'll try to provide a diagram of what I'm talking about.

Easy to wire up, but why?

Why would you want it to run on batteries? Major hassle keeping them charged.
A small oscillating 110v fan would be qiueter, cheaper, and easier. And provide much more air circulation.

You can probably find one for $10 at Walmart. Some things can be done. That does always mean they should be done.

If you just want to learn some basic wiring concepts, go for it.

Yea i could spend $10 for a fan in wallmart, but why not use something that i already have?

How would you wire it? I'm have no knowledge for wiring whatsoever . Is it possible for you to draw a small diagram for me step by step?

Because the time to do it, and the results, would not be worth the $10. Case fans are not designed to move a roomful of air.

As an exercise in teaching yourself, go for it. For actually cooling the room, not so much.

It's a small project, It can be use for a fan that just blows. I just thought of this project just out of whim. No harm in learning, though it might dent my wallet but what the heck.

kinda something like this?

Please anyone out there can also help me or teach me.

So you're trying to use computer fans that you have lying around to create an array of fans to blow air around your room right?

too bad you wont feel the air being moved unless you were a foot away from it, you would want to run it in parallel since they are depending on the brand, both low amperage and low wattage. id just recommend daisy chaining them with molex connectors and plugging it into your through your cpu, saves you money and batteries.

An easy way to do this would be to get an old PSU, plug the fans in to it. Mount the fans on a board. Use the PSU switch for on/off.

Now revel in the massive breeze (as long as you're sitting 8" away from it).

Well not anymore, I'm want to learn how to wire that's about it. Installing battery pack and switch.

USAFRet :

The thing is i kinda want it to be portable.

USAFRet · Apr 16, 2013

lookerup :

Mount the PSU to the board as well. Using batteries, you will get tired of it in about 3 days.

Google this:
basic electrical circuits

Study some of the links.

if you say so.

I've decided to follow this video: http://www.youtube.com/watch?v=klTfk6L7o6o since the principals are the same.

Positive to middle wire (Usually Red) and the negative end of the battery to the black wire (Ground). Try using a 9V battery, should be enough voltage. If not, wire a couple of batteries in series to get your 12 volts.

GreenToxon :

i want to attach it to a pc power switch. how would that work?

USAFRet · Apr 17, 2013

lookerup :

A PC power switch is momentatary on/off. Will not work, unless you are going to hold it in all the time.
