I as of early 2006 I could not find a powerful enough laptop cooler that was good for my use. So I made one myself. It's been working great for me so I thought I would share with others.


Here is what you need.

Medium Fedex box.
Two VHS tapes.
PC Fans. ( I use two 120mm Antec 3 step speed control Quite fans)
PC ATX power supply.
Small zip ties.
Large zip ties..

Step 1: Cut the Box

You can make it esay on yourself and use a medium Fedex box like I did.
Cut the box like the picture.
Start with the bottom part that is going to rap around the box.
Dude th fans should suck the air out and no need for a bulky ATX power supply just convert it to USB
it would draw too much current and fry the port.<br /> usb ports can only supply 500mA, motors draw heaps.<br />
<p>USB peripherals do not &quot;Draw&quot; current. - &quot;A common misconception by beginners seems to<br> be that a power supply will force its rated current through the load - <br>this is incorrect, only as much current as the load will accept will <br>flow&quot; In other words a USB Serial Controller does not draw out Voltage at an amplitude on demand, it constantly flows 5volts of power which peripherals can accept, the heavier the load the less there is for everything else, but it wont burn out it will just stop working until things are removed. Sending a return voltage or a short circuit can fry a USB serial controller. </p>
<p>lol if you use a small 30CM tower fan y0u could get better cooling, and a higher airflow</p>
If those are 12 Volt fans then why are you using a power supply you could have made it usb powered or used a 12 power converter and plug it right into the wall check out mine to see what im talking about...<br/><br/>click <a rel="nofollow" href="https://www.instructables.com/id/EHLRK6NF3SYTKC5/">Here</a><br/>
uhh, usb is 5v, and a converter would draw too much current from the usb, frying it.<br />
luv it! :)
that is what i call gheeeeetto! but i like it. nice job.
This seems pretty bulky. Couldn't you use similar sized fans but make it a little smaller. For example, you could put the fans at an angle, taking some depth away for the device. It does looks like it's easy to make, and effective.
Sweet, I like the looks and the usefullness, I am trying to build a laptop rack with cooling and this idea has helped.
I have a query, are the fans blowing air under, or sucking air out. If they are blowing under - as my laptop would need - what kind of output do you get. I ask this because it seems like the airflow might get disrupted by the hape of it. Other than this, and possibly some more info on rigging the fans to the psu, a great idea.
couldn't u have just spliced the fans into a usb cord so that u don't have to lugg that power supply along
no, usb wouldn't put out enough power to drive them both. Lower powered fans would work, or an inverter, or a ipod usb connecter spliced in - i think -
Good idea. Another thing you could have done was extend the box and cut holes in the top. That way the laptop could have rested on the box while still cooling it off.
ok, I made time and added instructions. :P
