how much can a top notch 120 rad do?

post #1 of 4
Thread Starter 
I'm about to build a small form factor machine. Due to the size of the chassis, I won't be able to install big heat sink coolers for CPU or GPU, and am thinking of going for a single loop water cooling system for both CPU and GPU.

But again, the chassis would be too small to accommodate any 240 radiator, not to mention a 360 one. Will it be possible for a top notch 120 radiator paired with other top notch cooling components to cool, say, both Core i7 3700 CPU and 680 GTX GPU? (I'm not gonna overclock much, if at all.)

If this is too silly a question, forgive my novicity. I've only dreamt about water cooling, but never had a courage to take the plunge.

If you're not overclocking, why not stick with stock coolers? It would be smaller and not to mention easier. The stock Intel coolers are pretty quiet, along with a lot of the GPU coolers out there.

Depends on what you will end up doing with the system. It will work, though temps will be elevated. It will likely still be a bit cooler than just using air. Ideally, you should have at least 120mm per device being cooled and in a perfect world an extra 120mm.

Also remember, you will rarely be maxing out both the CPU and GPU at the same time, unless folding or running BOINC. Gaming will typically use mostly the GPU and so on. It should be fine, but again, temps will be higher than having two 120mm.

Well, for one thing, a standard 680 GTX card is too long for my chassis, so that I'll have to remove the stock cooler. The bare card will barely fit, and so does a GPU waterblock not larger than the bare card.
