I have the materials / plastic already , I just need fans and adapters now and that's not the problem to me.
All I need now is , I'm not sure how to cut a hole in the center.
Anyone can help ?

I'm interested to make 1 for my lappy...Where can i buy acrylic in Jalan Pasar?

i use a 1/2 inch 3 ring binder. 2 RM

Hi sifus.

I have this fan (12V 1.40A):


which is of this size:


The connecter is:


which has four wires connected to it:


My question is can this fan be modded to become a DIY notebook cooler? If yes, please let me know how I can connect it to the power adapter... Thank you!

Your ideas/guidance will be much appreciated.

hi,

i think it can be moded ,
but i dunno which wire for your four wire to be connected to the adapter,(maybe red,and black only needed)
i give example of mine,
for my fans,i got 2 wire,which is red and black,
i cut both wire from the molex connector,and also the 12v power adapter,
i just connected the red wire from fans to the black white stripe wire from the power adapter,
and the black wire from the fans connected to the black wire from the adapter,
and just on it,
all working fine,
make sure there is no contact between black and red wire which are already connected to the adapter wire,
it will coz the fans not function,
just seperate it

p/s :this is just axample from my fans,any modification is your own risk

waooo~ cool man

Hi MildLO! Thank you for the reply!

May I have a close up view of the modifications done? Thank you so much!

hi, i will upload soon,now feel sleepy,hehe,
tomolo i upload,but quality of picture not soo gud coz i use my phone camera
i try my best

Just for information, 'niah' has got meaning: It's a Hokkien word and it can be used to substitute Manglish 'only'.

For example, if you're gonna say "Not expensive-lah, five Ringgit only..."
it can be translated to "Not expensive-lah, five Ringgit niah..."

hi DFlo,

Here are the pic:

My setup,using the files cardboard only :


this is the red wire from the fans connected to the black white stripe wire from the adapter,
i cut the connector originally from the power adapter and i use the wire to connected it to the red wire from the fans,
i just twisted it together to connect it,
i got 2 fans function while the other one i just disconnected it ,
u can see 2 red wire in the picture:


this is the black wire from the fans and the black wire from the power adapter,
just the same method,cut it,and twist it together to connect each other,
here are the blurry pic


hope it can help u,sorry for blur picture

Hey there MildLO, thank you so much for the pictures!

I have tried to wire my fan to the adapter according to your method - red to black white, black to black - but the fan won't spin. Now I'm wondering whether the current is not enough - the adapter is giving out 500mA, whereas the fan needs 1.40A?

Hi DFlo,
Sad to hear that its not working,
i use the 12 volt power adapter,
whut kind of adapter are u using?
i think your fans is performance one,sorry if im noob,
maybe need a higher volt i think

Same here, I'm using the 12V adapter but 500mA of current only... Hmm, maybe the fan is faulty

And please don't say sorry, you're not a noob!
