I'm going with the new "NV2" style Koolance vid block for 7800 cooling duties.
This block is a rediesign of KL's NV1 made to work with 7800's
I'm expecting good things :cool:

With 1/4" tubes and such a restrictive block, dont expect too much. That behometh is seriously going to impede your loop's flow; I think you would have been better off with a Maze4, Fusion HL, or even an NV68 (Im pretty sure they fit the 7800 cards), but good luck with the Koolance.

With 1/4" tubes and such a restrictive block, dont expect too much.Um, sure. I've cooled a 35W NV30 Ultra with a Koolance block on 1/4" pipeline, and had no problems in series with the CPU, northbridge, and second video card. Everything overclocked most excellently, despite the "restrictive block". The paltry 20-something Watts from a NV47/G70 GPU should have no problems on a Koolance rig.

No offence Achilles.....but you don't know what you're talking about or at least have no experiance with how good Koolance systems are.
I've had these blocks on most all of my 6800 cards...they do an incredible job, combined with a KL CPU-300 block and an EXOS unit, I have no cooling worries on this setup ;)

I had a couple of those on my old rig, cooling a couple of PCI-E 6800gt's, along with the 300 block and an EXOS AI. I sold them still on the cards when I upgraded to 7800gtx's and a new case etc (since found out they fit :o ). I thought they were pretty good, the cards sat nicely at 432 and the newcastle core I had at the time had a mild OC which sat at 33-34 even with both cards in the loop. Lots of people get all sniffy about EXOS stuff but I found it really good and very easy to maintain.

Have fun and Good luck with the purchase PAIN.

I finally got the EXOS cooling system with the NV2 block on the my 7800....
Wow!! ...I will check load temps later but for now feast on the idle numbers :)
stock cooler idle = 52C
EXOS NV2 idle = 34C !!

you are trying to force me to go back to water :d

sorry to do this to you Glow ;) ...have a look at these load temps @ 490
stock cooler = 67C
EXOS NV2 = 41C

I'm dead serious and thats with a CPU-300 block on CPU cooling duties in the circuit...

Heh typical reply from someone thats never used a Koolance. I had a koolance on my main gamin rig. Then after reading post after post about how much better 1/2" tubing was I was convinced my Koolance wasn't enough. Swapped my koolance to my server and then spent $250 on a custom watercooling build that included a Danger Den TDX, Maze4 GPU, Dual Heatercore and D4 pump. After installing and expecting a huge differance in performance and overclock I was quickly dissapointed.

I gained a 2C cooler temps over my koolance at idle. 5C under load. Net gain in OC = 50mhz. GPU temps were the same pretty much. Slightly cooler but no increase in overclock.

Anyway the Koolance stuff with its smaller and more managable tubing cools quite well. Fot a kit with its ease of use and setup its performance its awesome. Sure you can cool better with a custom build but you won't get much better performance out your system.

BTW.... Nice temps with that Koolance block!
