Just got the case today and I'm having trouble on installing some Jetflo 120 fans in front of the Corsair 750D. Can someone please enlighten me on how I may go about installing these things.

2 140mm fans should have been installed on the front of that case by default.

To change them out, you need to remove the front cover. It should snap from the top and rotate down to expose the fan area. Push on the 2 X's on the front of the case to unsnap the front cover.

For each fan, you will notice 2 sets of screw holes. 1 set is for 120mm fans, and the other is for 140mm fans.

The stock small fan screws or the jetflo screws don't fit through those holes. The long screws do but they are too small for both the mounting holes on the case and fan

Did the 140mm fans come with screws? If not, the fans simply may snap into place on the fan mount. You may have to run to your local computer store or hardware store to get screws that fit. After all, you are attempting to mate cooler master parts with Corsair parts.

Another question I have for you. Those original 140mm fans run 67.8 cfm at 24dba, each, and are quite adequate for moving air yet being quiet. Why are you trying to run smaller, noisier fans?

Noise isn't a problem for me and the sp of the Jetflos, added to the 95, give or take, cfm help with the 750d's suffocating the front fans. Also I've managed to ghetto mount the fans by using two short screws to mount the top of the fan to some of those other random mounting holes and 2 long ones to mount the bottom to the mounts that are bended, tried a wiggle test and it seemed mounted well
