recommend me some fans?

Wait a sec...if you plug a fan into a power socket that is controlled automatically by the computer (i.e controls the speed of the fan), surely any fan plugged into that socket would also be adjusted? Does it matter if you get the 4 pin 7Volt one or the 3 pin one?

IIRC a 3 pin one would go in a fan controller to allow you to adjust its speed & hence voltage. They only have 2 wires you need a 3rd one to be able to control it from the BIOS if you were plugging into a motherboard header. The 4 pin molex ones she sells are fixed to run at 7 volts

The 3rd wire is the rpm sensor.
