Yo :) I have a couple of 480's in SLI I'd like to cool along with a new cpu (waiting for bulldozer review) I was wondering if the
XSPC Rasa 750 RX360 kit with an additional 120 would be adequate to cool all 3 on a single loop? Would this even, be overkill? I have a CM Cosmos S case with enough room to run push/pull on both radiators.

I'm thinking:

Res>Pump>GTX480>GTX480>360rad>CPU>120rad>Res

Also unsure :confused: would a single pump be enough with these 2 radiators?

I'm a WC'ing noob and have never built a loop before so any advice is very much appreciated! Cheers

that will be fine

I'm thinking:

Res>Pump>GTX480>GTX480>360rad>CPU>120rad>Res

AGAIN, FINE

Also unsure :confused: would a single pump be enough with these 2 radiators?

AS LONG AS IT'S A POWERFUL PUMP LIKE THE LAING d5 (oops, caps lock!)

Make sure you do a LOT of rsearch beforehand :)
 
Besides having the res before the pump, the order of components isn't important. Once at equilibrium the temperature variation of the water around the loop is small.

Single 14W pump should be fine, I'd call the rads adequate rather than overkill as the 480s generate a lot of heat.
 
Thanks for the speedy reply guys. I have a couple of AXP's I was going to use on the 480's but they are huge and I'd quite like to make use of the extra pcie slots. The Rasa kit's appear to be great but I wasn't sure if the 360 and a single 120 would be enough - thanks for clearing that up :)
 
depends entirely on the heat output of the CPU
if you are waiting for bulldozer then at a guess, worst case scenario is going to be that bulldozer is around the same as a bloomfield heat output wise.

I would suggest more custom kit in all honesty. 480 SLI kicks out a lot of heat but they perform very well under water.

my 480SLI and my old gulftown cpu used to generate a lot of heat. where my 480 and 240 thermochills struggled at some points.

I would suggest a 360 and a 240 if you plan on doing it. either all on one loop or on two separate loops. 240 for the cpu, 360 for the 480s.

if you are doing a single loop, you are going to need a very very good pump.
 
Agree with the above. The 480 is a hot card and i would want more than a 360 and a 120 to cool a pair and a cpu. The X2O 750 pump that comes with that kit is not liklely to cut it either. Head height is only 1.8m. You are going to need something like the D5 to handle everything so you will be better off speccing up a complete custom loop.
 
Thanks again guys, I havn't given the pump a lot of thought just yet. I was thinking I would use the pump supplied with the Rasa kit but if this isn't up to the job I guess I'm better as pastymuncher said speccing a complete custom loop. As I'm new to all of this I'm still trying to get my head around all the pump variants and the price tag to match some of them.. The CM Cosmos S case has quite a bit of room I would have space for a 240 in the empty drive bays. I was thinking of hanging a few fans in there to help with airflow but now I'm wondering how easy it would be to mount a radiator in there instead? My other option would be to buy a second 120 rad and mount it at the bottom of the case. In terms of performance would 2 x 120 Rads more or less equal a single 240?

You can see the case has space at the bottom front for mounting a fan, space at the back and enough room up top for a 360 rad.

Cheers again all and sorry for being a noob :o

It may be best to mount a larger rad externally aswell

I'd quite like to keep the whole lot contained in my case if it doesn't suffer. I've seen a few externally mounted rad's and they look pretty awful (no offence to anyone with a similar setup) This will be in my living room and the case is already huge, the more discrete I can be the better.
 
okay, you could, i think get the followig rads in:

120 in the bottom
120 at back
360 up top
240 in drive bays

I would only stick a120 in the drive bays to give you space to put a res or mount a pump.

that will still give you, in essence, two 360 rads.

As said, you'll need a powerful pump. I would highly recommend THIS ONE

What are you trying to achieve with the liquid cooling? silence or performance?
 
in my opinion.
thermochill.
the only reason that I would have suggested a sr1 is because they have a few neat design features. but in fairness, the performance would be very similar.

in my experience, thermochills with very slow fans work really well.

what exactly is the difference?
 
How do you guys rate the Black Ice GT radiators? I'm starting to piece things together in my head. I'm thinking 3 x 120 and 1 x 360 as you said Cleeecooo this would effectively give me 2 360 rads. At the same time I'm trying to picture my way past the spaghetti junctioning of tubing it would require and I wonder whether I could get away with 1 x 360 and 2 x 120b:confused: I'm looking for a balance of performance and quiet operation. I basically want to up my overclocking headroom on the 480's aswell as the cpu. I'm likely to pick up a cherry picked cpu although I havn't decided which one yet.. I'm currently chugging away on a Phenom 2 940.

At the moment space is rather restricted I can get both 480's stable in SLI @ 825mhz but any more 'fiddling' causes the temps to soar into the 100's. I'd quite like to experiment to see how much I can squeeze out of these cards. £194.99 each bought a few months back here on Overclockers UK :D
 
2x 120 rads may equal 1x 240... but remember each radiator is additional barbs/compression fittings and hose so budget for those and work out how much more room you will need for pipeing the hose around.

I've got a Cosmos S with a 360 in the roof, if you add 3 more 120 rads, thats a lot more hose and connections to spanner up. If you dont need all those drive bays, you may find it easier to put a thick 240 rad in the front along with the 360 in the roof - or cut the base under the drivebays to expand that single fanslot to fit a 240..

My system is an i7 960, 2 x GTX480's and an 8800GTX (physics only) and all four components are cooled by a Zalman Reserator XT. Under gaming conditions the temp settles at about 40 C.

Andi.

Don't want to doubt your numbers but I assume you are talking water temp here I cannot see anyway how that kit can keep the actual components that low.

I run 3x360 rads and depending on fan speed my gpus go from 40 to 48 and cpu from between 52 and 58 under game load. Water temp is between 29 and 35 depending on ambient.

To the op you can cool the lot off 1 decent 360 rad (I have done this in the past) and the temps are fine, you just need to decide what you are comfortable with temp wise and noise wise.

From past experience the pa (or ta) 120.3 and SR1s are great rads but for the extra couple of degrees cooling potential you will get they are not worth it. Pick up some swiftech or koolance rads and save yourself some money. Just look for low fpi rads so you can run pretty low speed fans.

Have fun anyway!
