Nuclear Raspberry PI

post #1 of 7
Thread Starter 
I have recently purchased a raspberry pi model b, and for no reason at all i have decided i want to double the processor speed, i have some nice heatsinks for it, and i have some of these very nice 120 cfm fans out of my old server, the only problem is they are 12v pwm fans and the pi is 5v, does anyone know of a fan controller that would be small enough to fit in a case with the pi to power 2 of these fans? it doesn't have to be fancy and have adjustable controls or monitoring or anything, i'm going to have the fans at 100% anyway.

i was just going to use a small plastic case that's made to fit the pi, but instead i'm going to use the metal shell from an old psu out of a server that already has a couple fan mounts in it.

If your Raspberry Pi can't provide power for the fan, you'll need a power source for the fan. For that, there's this:
http://www.frozencpu.com/products/9106/bus-192/AC_to_DC_Adapter_-_110V_AC_to_12V_DC_Converter_w_Standard_4_Pin_5000mA_Max.html?tl=g47c271s670

Standard 120volt AC from a house outlet to a 12v DC with 5amp max of current in the form of a molex connector.



After that, you could use any standard fan controller. PWM fans DO NOT need the 4th pin to function, they just lose their PWM capabilities if they loose it.

What amperage do you need for your fan? I can't link a fan controller without that info.

or you can just take a cellphone charger and make your own, most of them run 12v and around 1amp

I actually made one today for my home theater cabinet
