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!

hi,

i think it can be moded hmm.gif ,
but i dunno which wire for your four wire to be connected to the adapter,(maybe red,and black only needed) sweat.gif
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 smile.gif

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

Hahahah.... niah = sound = syiok = no meaning

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..."

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 hmm.gif

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

hey guys!!!
how do we know that the holes or the fans underneath our lappies are blowing or sucking in air? and the holes  for the memory....we blow in air or suck hot air out?

and...can i use 2 fans with one usb?

haha thx for everyone's help!!!

I think the best practice would be to suck it out, rather than blowing it in.

As for two fans with one USB connection, I think it's possible considering that most (if not all) commercial laptop coolers have more than one fans but only one USB head, isn't it?
