"The performance advantage doesn’t just apply to the CPU," he said. "Routing all the CPU heat directly out of your chassis means lower overall ambient temperature, which helps out your other components."
That's great, except for the fact that the IDEAL situation is for the radiators of these units to draw FRESH air directly into them instead of working as an exhaust fan. Drawing-in fresh, unheated air yields maximum cooling. Working as an exhaust, the radiator would use air from within the case (which is likely pre-heated due to passing over HDDs, chipsets, etc.) through it, reducing the cooling effect.
What bugs me is that statements was made as if air coolers can't route CPU-heated air directly out of a case. Mine does, with a little help. It's aimed directly at another fan on the back of the case, which just happens to be identical fan to the one on the cooler on the same header, meaning they spin at the same speed. It's basically a push-pull setup without having them both mounted on the HS.
All that and it costs $70? I'll stick to a standard air cooler, since they're much cheaper and work just as well.
[citation][nom]jim5450[/nom]Positive air pressure matters most on paper, it's more hype than anything. Try running positive air pressure in one of the CoolerMaster HAF series for about 4 months, in a typical room that suffers from dust, and see how much less dust you actually wind up with.[/citation]
The key to a proper positive pressure configuration is controlling the intake of dust through the use of easily accessed and removable dust filters. (Preferably, external filters.) Cleaning and maintaining these filters simply comes with the territory. In a high-dust environment, positive, balanced, and negative pressure setups all end up with dust inside them if the intake ports are not filtered. The advantage a filtered positive pressure design would have is the dust can only enter through the filtered intake fan ports, rather than through every small crack in a case.
Positive pressure is far from hype.
