First post here, so sorry if it's in the wrong category, etc...

First build and I have a 120mm kraken x31 all in one cpu cooler that I planned to mount in the rear of my Cooler Master Silencio 352 case with an exhaust fan on top. It said a 120mm radiator would fit, but unfortunately this one doesn't fit the rear with the radiator screwed into the case (case:radiator:fan) due to the silencio's rear architecture. Should I switch the fan position so that it is case:fan:radiator or should I mount the radiator on the top of the case and put the exhaust fan in the rear.

Regardless of which is optimal I would like to know if it is okay to mount an AIO liquid cooler radiator to the top of a case.
 
Solution
Sure but know the top only supports a 15mm thick cooler. The only 2 places the company supports radiators are the front 240mm and the rear 120mm.

Push / Pull has minimal affect on thermals, so if you can go case : fan (pull exhaust) : radiator, that would be fine.

Top mounting is also valid, based on case design.
