Retail (Newegg) 6800 gets SMOKED (good way)

[Vric]

ok.. look like there is some good batch in retail too

impressive.

great work JC .
cant wait till my retail comes here

NB can get VERY hot indeed. and water doesn't have any effect on improving yields on NB. Only sub zero does to some extent.

There is a solution to that. Not too long ago, I saw a phase cooler with 3 seperate heads. One fore CPU, one for chipset, one for GPU. Now granted, it probably got maybe -15 to -20C temps at best, it's still subzero and it would still yield very good results.

you need to cool the chipset (put dry ice on it and you'll get almost unlimited fsb) to go for higher fsb that is the big secret of conroe.

This man speaks the truth. I upgraded my NB cooling and now I can hit 400+ FSB easily now.

Wow, holy moly. That's friggin' awesome.

peltier+water is a good solution if you wanna go nuts. While peltiers normally need to be super-powered to handle a hot overclocked CPU, the northbridge does not produce anywhere near as much heat. While I' not sure how much we are talking about, I doubt it could be more than 5-12 watts or thereabouts. In other words, a small inexpensive 80watt peltier should be able to bring it to sub-zero. An 80watt peltier like this

will use well under 100watts even at peak, and thus could alos easily be run on your primary PSU at 12volt as long as you have a reasonably beefy one (which is usually the case for us overclockers).

So yea... theres your solution when it comes to subzero northbridge cooling. much less complex and much cheaper than a "hydra" phasecooler for sure =)

While it is a lot of effort to squeeze out a few extra Mhz, I'd guess you'd see a noticable increase compared to stock cooling at the very least.

Actually, a good pelt setup isn't much less complicated or much cheaper than a "hydra." To accomplish subzero cooling on the CPU, GPU, and rad with pelts, you'd need three pelts, a CPU block, a chipset block, a GPU block, a pump, a rad, tubing, fans, and a secondary PSU to run the pelts. That would cost roughly around $550 or so for just a decent setup. It wouldn't be possible to build a setup that would compete with a Hydra, but a high end pelt setup for CPU, GPU, and chipset would cost around $1000. A pre-build hyrda would be more expensive, yes. It would be around $1500-1600, but it would yield better temps than would be possible with a pelt setup, and it would be slightly less complicated. And if you really wanted to save some cash, you could build your own tripple-head phase cooler for around $7-800 if you really know what you're doing and where to find parts. If you're talking about JUST a chipset cooler, then yes, a pelt would be a much better idea. But if you want sub-zero on CPU, GPU, and chipset, phase is probably the best option. Or just for coolness factor, phase is the way to go. But this has really gotten off topic...
