yesterday just made one DIY notebook cooler... .. take me about 2 hour to find the part around my home and shop and only with RM16 ..

12v PC fan =RM12
Tape = RM1
Connector= rm1
switches= RM2

Other is free....can find old junk part .

USB wires
hard cardboard file


I design one that direct the fan to my CPU and RAM HOLES....

By the way i using AMD.2.1GHz so the temp is about 70'C normal but when it run with games the temp will go up till 90'c like that..sometime even 100'c before shutdown..

Made my design simple just directing it ..beside i have to cut some more holes on my lappie bottom casing to let more flow going through it...opps..No waranty lorrrr....

Here some of the picture of my version...








here my cooling result


before




after





before cooling the cpu temp is 75'c and after switching on the cooling, it down to 64'c...the hard drive stay the same 41'c..

SO ..11'C drop in aircond room. but if in normal room the temp will drop about 7'c....wow. no need to buy at shop liao....

Do u have a 12v adapter? if use USB wire.. the wind speed wont be so strong and sometime wont turn abit....
but u can still use it if ur comp USB voltage is around 5v ...

use the black and red wires from the USB.. or some type of USB wire are different in color. so use the white for + and blue for --

adapter usually only till 12v only... but if u gonna throw in 2 fan... then pick the higher mA one... i am using 500mA for now...try 2000mA One.. any mall would have it... tesco or lowyat... or go for those china shop one...... got alot cheap adapter there..haha.....but dun pick 220v one..later spoil all u fan... pick 240v input to 12v 2000mA more or less..

it depend on your number of fan... if your cooler only have 1 fan the better use 9v output ..but u still can use 12v..just the lifetime of fan will be effected. Use a adjustable adapter..range from 3v to 12 volt. so u can adjust to suite your need..like when playing game , u can set to 12 v and normal usage set to 9 volt

it ok if the volt is round 220v to 240 volt because our home electricity is not always at 240v.. since your cooler have 2 fan then u can continue using 12 volts.. sure boots your fan speed alot..and cool your cpu down..

the size of the cooler dont allow bigger fan to be install inside it.. because of the thickness of it.. but since u saying that u only wan use usb as the power. then i could recommend u to find any of usb wire from mouse or from other junk.. wire it together with the existing wire of the cooler.. be careful with the wire color and positive negative....look up at my post above..for refer..

congrat to u falkenst115 ...

but i think u can make the fan run faster if u use a 12v power adapter.....if your lappie warranty if over then try play abit on the back cover too..u use amd proc rite..?

just go around shop sure got cheap 12v adapter...hp charger is around 5.6v...wont help much...

actually if u are fan of mod ...hehe....and if u got big car amplifier that using aluminium, u can dril and mod fan ..the result of cooling is much more trill...haha. anyways there is water cooling for lappie now... but for high end only....

watercooling for laptop system like below...aftermarket stuff

The yellow one is rpm sensor wire and to control it speed...the 3 wire fan is use for cpu cooler that plug in motherboard....so dont care about that yellow wire, if the fan can run with 2 wire...

yeah...still will run full speed...but cpu fan very noisy o...u sure u wan to use cpu fan..?
