Hi there, I recently bought a new case (nzxt phantom) and decided to begin overclocking my system slightly im running a amd 8120 and a gtx 560ti im looking to overclock the processor which will require me to upgrade my cooling for the cheap fan I currently have however my graphics card fan is quite loud and I want to upgrade that too is it worth going for a cheap water cooling system or to just buy separate gpu and cpu cooling as so far I haven't found that much good in terms of the GPU.
What sort of 560ti do you have? I have the ASUS DCII TOP and it is quiet while performing well. In general I would not bother with an aftermarket air cooler. You would be better of putting up with what you have.
If you really want to overclock it a large amount and you need vastly more cooling, then custom water cooling is the way to go. It will cost a bit and you will need the waterblock, pump and reservoir but the benefits are huge.
