I want to overclock my cpu to 4.2 gigahertz but I dont know if the fans for the Cooler Master Seidon 240M will fit on top of the case? Please help, I dont want to buy this then find out that it wont fit. Lol, thanks.
You need 2.1 inches of space to fit the radiator and fans, The radiator is 1.1" thick and the fan is 1" thick. Then the radiator is 10.7" long and about 5" wide so you should be able to measure the top of the case to see if it will fit. In trying to see the top space where you intend to mount there is no real clear picture that I can find to show if dual 120mm fans can be mounted. If you already have the case you'll have to look and see if there are screw holes in the top for mounting two fans. I know it says it will accommodate a 200mm fan but sometimes they put the holes there to mount two fans.
