CPU Cooling: Swiftech Liquid Cooling Components

We got such excellent results from the liquid cooling system of our March System Builder Marathon that we decided to keep it. The basis for our kit is Swiftech’s H20-120 Compact liquid cooler, with CPU water block integrated high-flow pump and reservoir integrated 120mm radiator.

Swiftech H20-120 Complete

We added an even larger dual-fan radiator to further improve cooling capacity, along with some extra hose, hose barbs, and clamps.

Swiftech Dual-Radiator Kit

Two fans were required for the radiator, and we chose the S-Flex SFF21E from Scythe for its low 20.1 decibel noise level and moderate 49 CFM airflow.

Installation was straightforward, but with so many components to manage we wrote an installation guide in March.

    Good Article, i'd still like to see more current generation games, such as COD4, Bioshock, Grid, Gears of Ware etc, I mean prey is a very old game and warhammer meh...

    Either way very well explained article, but for some1 like me the 8800 Ultras still sell for around 500$ here, and 3 of them would set me back 1500, while the GX2s 1000-1200:P

    Liquid, what was their old rig? Wasn't it 2x 8800GTXes? That pretty much squarely beat 2x 9800GX2s? So you don't need 3, only 2!

    Also, good point, they need to benchmark games like GRID and Age of Conan as well!

    Ahhh too bad about the videocard choice here. I would have liked to see a 2x GTX260 rig...I think that'll be the next power-gamer's rig without dropping the extra $500 on the 2x GTX280 and the extra $300 on a 1wK PSU...although I'm sure this 850W could handle it. I'm going to be running GTX260s on a 750W quality PSU...I predict absolutely no problems.

    Yes good article but I have to echo the exact sentiment from above. Prey is a fun game but it was never really the system killer to begin with. Some shader intensive games would be nice too.

    I think Nvidia is going to discontinue the 8800GTX\Ultras real soon here. Right now on Newegg.com they don't have any of either card. Over the last few weeks they've been sporadic as far as being in stock. I would consider adding another 8800GTX to my rig but like L1qu!d said they're still pretty expensive. The lowest price I've seen for the 8800GTX's is around $350. If I could find one for $250-$300 range it would be worth it.

    Yeah because I kno in certain games tri and quad scale better. Age of Conan, COD4 are some examples:)

    Are you high? 2 GTX's on an 850w or even a 1KW PSU? With all the other peripherals installed, no way. Asus's new top of the line ARES rig uses 2 1KW PSU's for three GTX 280's. So GTX 260 SLI rig will need a minimum 1KW.

    Nice article guys. Its funny that a $1,200 could beat that $4,000 rig in a lot of games/benchies. My E8400 @ 3.8GHz and SLI 8800GT get around 18,000 3dMark06
    Can't wait to see how the other test builds are going to perform.

    Of course it beats it in some things, it's overclocked. All the systems will get overclocked on Monday.

    Well I was using an instanced case...I'm not going to be running mad-donkey peripherals. Plan is 4 HDDs, 1 DVD burner, 2x GTX260, E8400, bunch of fans and LEDs but those are tiny draws.

    Dude anyways, no, 1kW is overkill. Look at this build! A quality 850W for a water-cooling rig with a QX9650 and 2x 9800GX2s! The GTX260 draws like 10W or more LESS than the 9800GX2, plus I won't be running a quad core OR water cooling. 750W is completely sound. My plan is for this rig to last me until Nehalem so I don't think I'll be going quad core on it etc.

    I am shocked, I must give Tom's a hand for this build it was well thought out and they picked the right parts. Only thing I do not like is the TJ09 case, that case does not cooler very well, an Antec 900 beats it with all fans on low, sad. They need to drop the TJ09, I had one and returned it, because it's cooling performance was not great, for a $4k gaming rig you need GREAT cooling. The Cosmos S is not much better, but there are so many other cases on the market that could fit that cooling system in that are a lot better and much cheaper. Oh well, besides the case GOOD JOB THW!
