Watercooling queshten

[triggaahappee]

Can i run a single loop for a Gainward GTX 570 and a i5 2500k with a single 240 rad in push/pull as well as a single 120 rad?

Yes.

What would the difference be between 240 rad + 120 rad and a

240 rad + 240rad

 

[Cleeecooo]

The 240 + 240 will be capable of cooling more thus possibly leading to more overclocks.

The 240+120 will be adequate.

 

[Jokester]

The extra 120mm fan will give you slightly better cooling capacity.

Around about an extra 33% cooling potential.

So if you were to get (say) 12.5C temperature difference between water and air using the 240+120 at max fanspeed, you would expect somewhere around 10C delta with the 240+240.

In practice, you would probably see somewhere in the region of 2-4C drop in temperatures at peak load.

Well the difference in price between a 120 and a 240 rad isn't huge, so it's more an issue of convenience.

If it's going to be a hassle to get that extra radiator in, then just stick with the 240 + 120. That's going to give you plenty enough cooling for a CPU and a single GPU with some decent overclocks. But if you can fit the second 240 in easily then it's a fairly cheap way to boost your cooling performance. You could probably get away with running the fans slower, or run them at the same speed and drop a couple of degrees from the GPU temps.

Not a huge difference in practice, but if they'll fit easily I'd go for it.
