Will these go together ?

I'm afraid not. The Corsair H50 is an all-in-one liquid cooler, it does not require any additional parts, nor is it compatible with any additional parts, other than perhaps a second 120mm fan in push-pull operation.
 


ohhhhh i see so all in one liquid coolers cant go with that. can you give me an example of a liquid cooler that would ? thanks !

 
If you want an all-in-one liquid cooler that is compatible with aftermarket parts, try the Swiftech H220. I don't know if they make a smaller all-in-one unit than the H220, you'll just have to look at their product lineup.
