heres my thing with OCing... I didnt build this unit with the purpose of OCing yet. Theres a reason I did this build the way it is. I am planning on adding another 3x120 radiator in the future with a bigger case.

I just dont think the one 2x120mm radiator will dissipate enough heat to OC yet. This was my first time getting into water cooling also..

I agree to a certain extent where if you are going to spend 300$ buying parts for WC then you might give OCing a shot but it depends on setup.
