Comparing 2 Koolance Cases

[Smartazz]

I need a liquid cooling system for overclocking an intel 805 and a 7900GT, I may bump it up to 2 7900GTs next year, is it worth it getting the 680 watts, or would the 380 handle the job just fine?

nvm I don't know what I'm talking about

But, I wouldn't think the 380w would be enough. Perhaps someone with more knowledge can answer.

It depends on whether you have the resources to commit. 380 watts of dissipation isn't bad and covers what you have now. 680 would well cover what you have now, and deal with any possible upgrade for the foreseeable future. If I were you I'd go with the 680.

Would have a second radiator and fan contribute greatly to the sound?

Greatly? No, not for the most part. It depends on the fans used too. Aren't the fans in a Koolance rig controlled by user setting?

User or automatic.

Go with the 680. Think about it this way. Say your system is outputting 350W of heat. Sure the 380 will dissipate that, but at full speed on the fan. If you can split the output between the 2 radiators, you have two working at 175W, which will obviously be quieter, since they will both be running at lower RPM, rather than 1 at high RPM.

Plus the 680 = upgradeable.

Two radiator systems don't work that way, at least not in linear homebrew systems. The first rad dissipates as much as it can, up to its ultimate potential. Any residual thermal energy bleeds out at the second rad, but this rad never reaches its ideal operating environment.

Alright thanks.
