[citation][nom]Crashman[/nom]Did you read the article? Everything was disclosed, including the fact (read the June build with the same case and fans) that externally-vented cards originally picked for this build would have reduced case temperature, followed by the fact that a side-panel fan was not ordered because the original order used externally vented cards. Further disclosure was provided in the article stating that, had we known the substitute cards would be internally vented, the fan would have been added to the order. That would be one additional fan, not three because the case is otherwise filled with fans. The only thing I mentioned for experimentation was using the added side fan as exhaust, rather than intake. With everything completely disclosed within the article, there's nothing left to admit.[/citation]
When I said "a couple" of fans I enumerate that to 2, not 3.
While there is plenty of disclosure (good for you) I maintain that the fail happened because original plan was not a good one. My experience with NVIDIA reference externally vented cards is that they still put a large amount of air and heat into the case. Just look at them, that have large gaps and/or slots in the shroud near the card edge.
While I love the 300 for budget builds (I've used several) a tight M/B dual card build with one is a poor plan unless special ducting is used to get fresh air into the sandwich space on the intake side, and hot air out of the sandwich on the exhaust side.
So to make it perfectly clear, I think the original plan was perilous to begin with. I would have ordered that extra fan along with the externally vented cards, plus another (custom internally mounted) fan for driving some serious internal ducting, plus some craft foam or something to make ducts with. If Tom's is not into that sort of thing, then the 300 was really the wrong choice. It is both a great budget case and a great modder's case, but if you're not planning to mod for a tight hot dual SLI setup, then you're planning to fail.
