Cooling 2x120 rad be good enough?

Ok well I'm going to water cool my pc soon and i am gonna be water cooling my hard drive(i got the block for free) my cpu (3.8ghz core i5 750) and my 5850 at stock.
Would a 2x120 rad be good enough or should i had an extra one?

 

A single 2x120 might be on the small side. I think it would work much better with a 3x120.

 

i dont have enough room for a 3x120

 

Hm, then atleast remove the HDD water cooler. Unless you have a pump that kicks quite a punch it will just restrict flow. HDD's, in most cases, do not need cooling. You make sure to have some kind of airflow over it.

 

it does 600 liters per hour

 

well im off to work read this when i get back

 

you at least have room for a 120.1 and 140.2 in the PC-K60, that is what I'm planning with mine, 120 on back fan, and 140.2 on top with some modding to make it fit under the top bezel and over the mobo.

 

i am using a nzxt whisper and i want to have all parts of water cooling inside
