Input: I ordered two of these fans to replace the 200mm fans in a Cooler Master Storm Enforcer Case.  What I quickly found was the universal mounts that come on the BitFenix make it not fit in the Cooler Master case.  Others have said the same regarding this product and other Cooler Master cases.  Thankfully I have a full tool shop and was able to take the fans to my jigsaw and cut off the extra plastic that was blocking their installation.  That being said, that is NOT the reason I gave the product a 2 star rating.<br /><br />The reason for the 2 star rating is due to the self tapping screws that come with the fan.  They are ABSOLUTE RUBBISH.  The screw is supposed to seat itself into the plastic mounting hole of the fan for installation.  This requires quite a bit of torque on the screw.  I am by no means a muscle head, but without fail, each head on the screws supplied got stripped while simply trying to turn them in by hand before they were even flush with the case.  This happened with no less than 3 different screw drivers, just to make sure my tool wasn't the issue.  I then had to take needle nose pliers to back each screw out.  Fortunately the screws that came with the Cooler Master fans were still around.  I twisted them in with no issue and now have the fans mounted.<br /><br />Having gone through all of that, I would say avoid these fans and stick with Cooler Master.  Though the Cooler Master fans may not move as much air (reportedly), they are superior in quality.

Will not fit a Cooler Master Storm Enforcer case without heavy modding.  Screws provided are garbage.  Avoid.
