suggestion for power supply ( DIY laptop cooler fan )?
I'm working to make a DIY laptop cooler fan.. the problem is I don't know which power supply to use ( not USB ). I already have 3 different fan, which is, 1 using 12v ( mo/bo fan I guess ) , 1 using 5v and 1 also using 5v but it has 3 fan.. both this 5v fan from broken cooler stand.. only the fan still working.. right now.. i'm using my Nokia charger with a little modification( OMG.. I don't what will happen next ) but the 12v fan is not functioning.. which ' size ' of power supply I must use if I want to operated all this fan by using one power supply only.. please help..
I'm sorry, my English very sucks~ I admit :-(
