You haven't done much looking then. It's a 12vdc, 2.2A, PWM (3.3v) controlled fan. It's not your typical fan either, so finding a replacement will be a short look as there are only a couple that will fit in place of it. If you plan to do some actual modding then you'd know what most of the specs were already since they're on the sticker on the fan, and if you plan to swap it out for something else then make sure it will move a ton of air, because the PS3 fan does.

The PWM line is 3.3v and has a duty cycle of 20% to 100%, though the fan should have at least 30% put on it at first for a few seconds to ensure it starts up, then it can be set back to 20% to run, but at that slow of a speed it doesn't move much air at all. This is how the PS3 controls it also.
You can use several methods to control the PWM line, from using a 555 setup as an Astable to using the PWM of some PIC. What you can not do is wire up the PWM line to some POT and control the fan speed that way, it's not effective and doesn't work worth a squat that way. Though if you want the fan to run at full speed all the time (100% duty cycle) then you can just put 3.3v on the PWM line and that's that, but it's right noisy.

I was wondering what kind of fan that you could fit inside the PS3 Case and or what kind of cooling mods you can do? I was wondering because my friend has a PS3 that breaks down once a month because of overheating. Then he changes the cooling pasta and puts everything back together and it starts working again..
My friend has bought a new PS3 slim so he was wondering if i wanted it. It would be really cool to be able to get a PS3 for the cost of Arctic Silver and a couple of fans..
