I'm going to cool GTX280 with full block and E5200 OCed in one loop with two radiators: 240 Swiftech and 120 XSPC. Swiftech has two Noctua P12 fans and XSPC has Yate-loon SL...

Question is - do I need that 120 radiator in the loop? I saw many loops in many cases that had one 240 radiator and cooled CPU and GPU easly...
What kind of difference in temperatures I may see here with this additnioal 120 radiator?
Can I get away with 240 rad and OCed Core2 and GTX280 in one loop and have temps in load no higher than ... don't know.. 50-60CC?
 
You should be fine (depending on your ambient temperatures and your case cooling of course).

I'm running Prime 95 at 3.8GHz on a Q9450 atm with a GTX 280 in the loop and getting load temps of 47C with a 120.3 Thermochill, so with 2/3 the cooling potential you should still be below your 60C limit.

You're probably right.. but 2/3 is too much I think - with Swiftech 240rad its probably less than 2/3 of PA 120.3 - but still I have dual core compared to your quad... so maybe it would be even...


For example here's a guy who has Phenom 4core and 2x 4870 in CF cooling in Lian Li A05 on one 240 Swiftech rad... getting idle/load: CPU=30/40, GPU 40C...

So I may be ok, with dual core and one GTX280.. what do you guys think?
 
my friend had a Q9550 at 4ghz and a 4870x2 with a larege overclock cooled off a 240 rad and his temps were fairly decent. under 60 load, i think under 50 load. so you should be fine.

What i'd be asking is,
"are these builds using just a 240 rad with cool temps running high speed noisy fans?"
 
I'd split the loop if you can, put the GPU(s) on a separate loop, especially if you want a quiet system with room for overclocking.
