[TR] BFG Tech unveils liquid-cooled GeForce 9800 GTX

When Nvidia and AMD unveil new graphics processors, most card makers prefer to pair them with stock coolers (or at least equivalent solutions). Occasionally, though, one company wanders away from the pack and uses a more outlandish cooling scheme. That's the case for BFG Tech, which has introduced a GeForce 9800 GTX graphics card designed to fit liquid cooling systems out of the box.

Instead of a heatsink and fan, the GeForce 9800 GTX H2OC 512MB features a water block with 1/2" and 3/8" fittings BFG says accommodate "most liquid cooling systems." The water block supports two- and three-way SLI configurations, as well. Counting on liquid cooling to handle the extra heat output, BFG took the opportunity to overclock the card from the stock 675MHz core and 1688MHz shader speeds to a respective 780MHz and 1944MHz.

BFG claims its card can run up to 28°C cooler with liquid cooling than with the reference Nvidia heatsink. That's due not just to the higher efficiency of liquid cooling, the company explains, but also to the fact that each 9800 GTX H2OC 512MB "is hand-built by a trained BFG technician using Arctic Silver thermal compound."

Sorta off-topic, but whatever happened to that liquid metal cooling that one company was working on for ATI cards? Been a while since I've read something about that. I think the company was Diamond but I'm not sure. Anyone know what I'm talking about?

BTW lol at "H2OC", that's originality right there.

"is hand-built by a trained BFG technician using Arctic Silver thermal compound."

Refers to official BFG tech manual :

1) clean surfaces with 91% alcohol and rag
2) add small dab of AS5 on core
3) spread evenly on core with finger inside plastic bag
4) install watercooling block
5) welcome to the BFG team! Your starting salary will be $35,000

Isn't there better Thermal Pastes than AS5 now? Such as Tuniq TX-2 and OCZ FreeZe?

Anyway, 8800Ultra Leviathan anyone?

Shin Itsu, Coolabatory liquid metal, etc

AS5 isn't really at the top of the list anymore - it's just earned such a reputation and widespread use that most people identify with it as being THE thermal compound to use

the barbs can go on either side. You just take a wrench and pull off the caps on the other size, swap em.

At least, thats what Ive seen people do with full cover blocks before.
