RX360 vs RS120+RX240

post #1 of 4
Thread Starter 
Hello there. I've been thinking lately about building a watercooling setup for my i7 930@4Ghz and 2x HD6870 in the same loop. But im not able to make up my mind for the radiator(s). The fans will probably be 3x 1500 RPM fans of unknown nature yet in push position.

I'm wondering which setup would be best; either a RX360 (or maybe RS360 would be enough?) or a RS120 after CPU and a RX240 after GPUs. The second option seems the best in my mind, since CPU heat will be dissipated in the first rad before going to GPUs. What do you guys think? Much differences between the 2 setups?

Thanks

the 360 should give you slightly better temps i think and it should also offer less restriction. As long as you have room in your case i would go with the RX360 all day. Mine works works amazing with some push/pull yates at about 1500rpm

Im a Nvidia guy so im not sure how hot 6870's run but with a oc'ed 930 and CF 6870's dont go any less than a 360 or equivalent

I have one and it is great. just picked up a 800D today so i'll be adding a RS240 in the bottom and my RX360 up top!

RX360

your ATI....oops....I mean AMD gpu should run fairly cool. the new gf104 based nvidia gpu are far cooler than the gf100 (gtx 465/470/480) btw.

Actually the 120 plus 240 will do slightly better than the 360 in heat dissipation. I tested the RS120, 240, 360 family and got the following:



If you look at the MCR series you will see the same thing.

Not much different though, for all practical purposes you can consider them equal, 120+240 is roughly equal to 360 with a very slight edge in separate radiators.

Restriction on the RX is really low, so I wouldn't worry too much about that.


Why? I'm not sure, but would guess there is a little more turbulence at the tube ends that dissipates better? Or..maybe it's just the tank ends dissipating a little extra heat.
