Just got an H100 to put in my Phantom rig at home. Wanted to put in the radiator mounted with 2 top fans and 2 bottom fans and mount it all inside the case however the Gskill Ripjaws X ram I had created a small problem. They have pretty large heatsink spreaders so trying to fit the radiator with 2 top fans and 2 bottom fans was a bit tricky. There just wasn't enough clearance for the added thickness since the ram would prevent me from fitting it all inside.

What people would suggest to do was to use the radiator mounts the case comes with, but bend them outwards towards the side panel so you can avoid contact with the ram heatsinks, but I had another idea.

What I ended up doing was mount two 120mmx38mm fans on the bottom base of the radiator then mount the radiator into the top of the base of the case, as if I was mounting it in just a push configuration. Then I mounted the other two fans on top of the base. So instead of having them inside the case I have them in between the mesh grill base and the top of the exterior case. This way I still had them setup in push pull config and with slightly longer screws I could also screw them into the radiator itself because with this case you would only be able to screw in the middle 4 holes.

Quick note when putting the top panel of the case back on, one of the plastic things with a hole to screw in the mesh panel juts out a little too much and ends up pushing the side of the fan just a little bit but the top panel will still click in fine. What I did was just file off the plastic so that it doesn't run into the fan at all. Its not necessary but I didn't want any pressure on the radiator. Its only one hole anyway and not a big deal if I can't screw it in since the mesh panel had like 5 other screws holding it in place anyway.

Anyway here are some pics:

In this first one you can also see a small mod I did just to add in a 140mm fan in the optical disc drive cage under the lone disc drive I had. This draws in cool air into the case so the bottom two fans on the radiator can draw it into the radiator.

Here you can see how the top two fans are installed on top of the exterior of the case, instead of on top of the interior of the case. This way you only need the radiator mounted inside with the two bottom fans, giving you enough clearance for the large ram heatsinks.

Here you can see the fans in between the top bezel and the inside of the case. Usually the fans would all be inside the case, but the added thickness would run into the ram heatsinks.
