ok this is what u must have..a 12volt fan.(any brand should do it)... any brand power adapter (u can found it at mydin,giant or hardware store) just ask the for assistant u searching for power adapter...it either adjustable one or fix one...u have to mode the power socket pin...change it to 3 pin connector output....a bracket ring,as u can see at my 6 fan laptop cooler...if any question regarding this mod i would happily to help....

sure the cheap PSU for desktop should more than enough...BUT WARNING...u playing with 240voltan there.....consult with the expert....and supervised by people who now about it...     

ahaks.. just found this topic..

currently using coolver master notepal U2..
very impressive cooler, and what i like most, u can reposition the fan anywhere u like..

and to upgrade it, i add with Kaku (formally known as Seada) 240 AV fan on the cooler.. result? very satisfied!

will upload the pics later..huhu

adding another fan..  originally got 2 x 5V fan, powered by USB.. then i add 1 more fan..

for the 12V fan, i modified it, connect the fan with AC power adapter.. currently i add this fan to my router, as it on 24hr non stop, easy to get hot..

basically i'm using adapter like this one..

Too true XD

Last month the fan was positioned to blow upward .... 2000rpm everyday
1 week the pad already showing visible bunny dust >.< scared all my laptop hole will be filled with dust.

Now it is positioned to suck the air downward at 2000rpm ...... the tradeoff is very obvious my keypad seem warm at 45-50 C last time it was cool enough ....... add more fan or increase the blow out hole for the fan

Here the picture as promised ...... haven't finish though no idea where to squish another fan on it~
