Cooling for I7 920 and (2) 7970s < Preferably one loop>

I currently have my i7 920 overclocked to 4.0ghz @ 1.28volts

HAF 922 case (think thats right, check my sig)

My 7970 is running at stock and my ambient temperatures are generally 20 degrees Celsius in the house.

I ve read the waterloop guide and several reviews on the "round-ups" of gpu/cpu blocks. When it all comes down to it 1-3 degrees difference is not a deal breaker for me. Functionality, installation, maintenance, cost, and aesthetics all play a role. For this reason I ve narrowed it down to a few choices and I really want suggestions on those or if you have something that is outstanding Ill gladly entertain that. Here are my CPU choices:

Apogee Drive 2 $144.99


Apogee HD $69.99


Koolance 380 $76.99


XSPC Raystorm $62.99


I am currently leaning on the AD2 due to it simplifying my loop, saving some cash on a pump, and it just seems cool to me. After that the Koolance seems to be the best performer and quite affordable. Quickly followed up by a nifty XSPC which has a great bang for the buck, slightly less performance, and a nifty LED. All in all though I would say the AD 2 and Koolance are my real contenders.


As far as my GPU blocks I ve narrowed that down to two products the heatkiller and swiftech komodo.





I lean towards the Swiftech block so that it all matches and I enjoy the overall cleanliness of the look, but I ve heard the GPU block is a bit restrictive. After that it seems the Heatkiller block is the best performer, but I m open to some reviews I may have missed.

As it currently sits I only have one 7970 and I will add the second into the loop in a couple months. I d like to just get the system underwater and get my feet wet before grabbing a second GPU and really going all out.

I would also be welcome to radiator suggestions for this style setup. Lastly, if the AD2 is not a winner, something along the lines of this was a heavy option. It is very clean, multi functional, and just seemed cool. Thanks in advance guys!

Do you think it would be enough for one gpu and then add an additional in series with the second card?

Well would it be ok to build the loop based on that pump since I will only have one 7970 for the start of it? Then add another in series with something like the Koolance reservoir/pump controller?

I d like silence and performance if possible. Btw the pump on the block is able to be replaced so it doesn't mean a total loss if it dies.

Right now the most noisy things are my Frio cooler on the CPU and the GPU fans. Once those are gone the case fans won't bother me.

Do you think the Koolance setup would work in series, or is their a better recommendation?
