the case fits either a 120mm or a 140mm case fan u can not fit 2x fans the only way u can fit 2x fans in front is modding ur case which is what i did.
1 where u have the front drive bays make sure 3x are free
2 only a 120mm fan will fit
3 cable tie each corner of fan to case
it does work i no ive done it
hope this helps
