Can't disagree about the noise, Anthony, but I've actually been a bit disillusioned with PC cooling the last few years anyway. There are so many different ways manufacturers could be dealing with the heat that it's no longer very funny. I mean, to force a graphics card manufacturer to burn as many watts as they do, to generate the graphics we expect, and yet keep their silicon cool in such a small footprint, seems a bit absurd.
Take the BTX standard for example, it was an attempt at alleviating some of the heat problems in PCs. If that could be expounded upon in a reasonable fashion, I think leaf blowers would be a non-issue.
In the mean-time, I have mitigated the problem by just removing my computers to another room and running high quality cabling from them to my console. Problem solved, regardless of the noise and heat that may be being generated. It goes somewhere else. I understand not everybody has the luxury of an unoccupied room to move their equipment to, so better ways to deal with heat would be nice.
When is somebody going to design an aftermarket cooler for graphics cards that ducts to the outside of the chassis, so it can actually draw from cooler, outside air, rather than the warmed air inside the computer case? I can see something like this being especially beneficial in dual card configurations, where heat becomes ridiculous in short order.
Water cooling with a full or with Closed loop coolers does the trick. I have a H100 with two 120mm fans roof mounted on my Haf 912+ case to take care of CPU heat. Eventually I'm going to buy a 290x and probably a http://store.nzxt.com/NZXT-KRAKEN-G10-GPU-BRACKET-p/rl-krg10.htm with a outside mounted CPU cooler with inside fan to transfer GPU heat outside the case. PSU vents from bottom and exhausts back. The airflow inside of my HAF912+ is great and temps are pretty low with all case fans installed.
