240mm radiator on a 200mm fan?

[realSpoderman]

I want to get the Corsair 600T White Graphite case and it already comes with all the fans it can hold, a 200mm in the front another one on top, but I can replace this with two 120mm fans, and a 120mm in the back. I also want to get the Corsair H100i v2 radiator which is 240mm, so can I just put the radiator on one of the 200mm fans or should I get the two 120mm fans and put them on the top?

you need 2x 120mm to get the max airflow through the rad fins

You'll want 2x 120s on the rad if you want the best cooling performance. Plus you'd have to screw the rad into the fan, or the fan into the rad depending if you have it in a pull or a push config, if you keep the 200mm fan there, you wont be able to secure the rad properly to the case, or the fan to the rad.
