Good evening one and all, I am after some advice on my loop. I have currently got a 2600K cooled by an EK 360XT rad with a D5 connected directly to an XSPC acrylic res. I have purchased 2 x Razor waterblocks for my GTX680s in SLI and have an EK 240XT rad to add to the loop. Will i be best off buying another pump and doing seperate loops or will one D5 cope with the lot? I used to have 2 x GTX480s in a single loop with the 2600K going through a 360 rad but got problems with the coolant getting too hot, hence the purchase of the extra 240 rad. Any suggestions gratefully received, and please be kind this is my first post ;-)
 
Welcome to the forum.
The D5 should cope fine, rads are usually quite low restriction bar a few exceptions (those EK are low). You didn't specify what cpu block you have but unless you have something like a swiftech apogeeXT or a design with a fine nozzle it shouldn't be high. Most recent ones tend to be designed as medium-low restriction. There is no data I could find off a quick search for the gpu waterblocks but the same tends to go with gpu blocks, high restriction blocks don't really offer anything over well designed lower restriction blocks so most don't bother.

So it's personal preference really there's no definitive answer. Seperate loop routing ease or lack of, pump redundancy/ noise may also play a part in your choice.

If it helps set your mind at ease the GTX680 is actually lower power than the GTX480 was (GTX780 would be the modern equivalent for heat generation) and so with your additional raddage you should be fine, and I would expect a D5 to cope with all that fine as people have said.
