The manual says 4 but really it depends on the current draw of the fans, it is rated for approx 12 watts so at 12 volts it means 1 Amp . For example the CM 120 R4 fan is rated at .37 amps so 3 of those BTW they are fantastic underrated fan , very quiet and flows 70 cfm ,also has good static pressure for use with a lot of rads as well. Manufacturer website should have model number. I won a CM storm trooper at Toronto Lan party but have not opened box because I already have 5 other CM cases otherwise I would look inside. Someone will tell you shortly because there are lots of them around. I`ll check back later if no answer but I bet they are the R4 version.
