Specifications of the Rosewill RCX-Z4

As you can see from the specs listing above, the Rosewill RCX-R4 uses a 120mm bearing fan that is capable of pushing 67.5 CFM. It should also be noted that the official specifications state a 3 or 4-pin connector can be used, this is referring to a 4-pin Molex plug and not the new 4-pin PWM type found on many new CPU coolers.
