Hello all you pro modders. I have reciently acquired some very nice fans for a song & I want to put em in my case.. I have a Coolermaster Praetorian Mid Tower that came with 4 80mm CM Fans. 2 intakes in frount & 1 exhaust in back & 1 on top. The case has a good field of flow but i want to improve it, the fans i got are a bit bigger but have wonderful flow rate & sound rating. I think that the top fan will be very simple to change out as there is plenty of room there. The frount fans should not be too bad either a bit tight but looks to be doable. the problem is the rear fan. The 80mm fan that is already there pretty much fills the available space on the pull out tray & due to the shape of the tray I am not sure i can fit it in any ideas or suggestions would be greatly appreciated. the Fans stats are: PAPST DC FAN Model 3412 / 2 DC fans with electronically commutated external rotor motors. Fully integrated commutation electronics. With electronic protection against reversepolarity, blocking and overloading; partially impedance protected. Fan of fibreglass reinforced plastic. PBTP housing, PA impeller. Air exhaust over struts. Rotational direction CCW looking at rotor. Electrical connection via leads AWG 24, TR 64. Stripped and tinned ends Mass 100 g. Technical specifications Patch cord 3-pin board AC/DC DC Dimension A 92 mm Dimension B 25 mm Dimension C 82.5 mm Tachosignal Yes Bearings ball bearing Nominal voltage 12 VDC Noise 36 dB(A) Power input 2,4 W Nominal speed 3050 min-1 Air flow 84 m3/h Weight 100 gr.
How big are the fans you're using to replace the CM ones? You can find 80mm->92mm converters pretty easy, however it does mean your case has to have space as these things protrude slightly more deeply than just a fan. Not so sure about 120mm fans though. Can you post pics?
