This summer my trusty TJ65 suddenly said goodbye to the cruel world and started shutting down every 20 minutes or so. I figured out it was an overheating issue. I browsed around to buy one of those fancy cooler pads than just gave up, not feeling like to give $50 for a PC fan in a box.

I decided to build my own, needless to say, for much cheaper.

What you will need (and probably have lying around):
- old desktop DVD player or something similar with a metal housing that fits under your laptop
- smaller CPU fan
- some usb cable (can be anything, we only need the plug)
-  electrical tape, glue, solder

- small metal saw (or dremel if you are into that kind of thing)
- soldering iron
- knife, screwdriver

Step 1: Remove the guts

I decided to leave only the power switch (why not), the power cord (we'll attach the usb dongle to this) and the scart socket in (because it would have left a needlessly large hole). Plus I glued back the plastic cover of the dvd tray and the buttons to give it a funky look...
you could add more fans :-)
Hmm... I have a bunch of old directv receivers on my parts shelf which could probably work quite nicely. I could even tap into the buttons on the front to do fun things....
A very cool cooler :) I'm currently using a targus something-or-other to put my laptop on, but now I'm thinking of remodeling my old Dreamcast to a netbook cooler.
Thanks :)<br>A cooler from a dreamcast, well that would look funky, please post a picture if you do it :)
all in all, nicely done.<br>choice of location for the fan is everything, for a laptop cooler.<br>looks like you choose the hard-drive cooling location.<br>good choice,<br><br><br>usb is DESIGNED for 5 volt under load.<br><br>in actuality, poorly regulated usb ports can pump out 7 volts or more, under dead short.<br><br>the other half of why it works is, the 12v fan can start on lower voltages, and run on even lower voltages.<br><br>In my testing, MOST smaller 12V fans can start on around 5 volt, and run down to around 3.<br>The higher power fans, like case fans that &quot;ratchet&quot; when you spin them by hand, tend to need higher starting voltages. usually, 7 is a minimum, and 5 is the low end running voltage. anything less, and you tend to get stalling.
Wow, long post thanks :)<br>Well yes actually the TJ65 blows out air at the back, and has two grills for sucking air in on the bottom, so I put the fan to the further one with face up so it blows air in.<br><br>As for the fans yes, absolutely true... <br>For me it was either this or two chipset/graphics card fans in parallel (those run on 5V). I chose this one because it has more than the average blades and makes a decent airflow, plus I only needed one :).
