Well i'm pretty bored and since i never come around much anymore i thought i would make a post.
During winter i have been messing around with idea's for better air cooling ( got a couple google sketch ups of other ideas ). Well one of my idea's i just jumped in and started tackling it hands on. This idea allows for air cooling with very good results, though the one flaw is that it is season based. During the winter months i achieved a pretty impressive 15 - 20C on all major components ( Ram, Chipset, CPU, GPU ) all on stock heatsinks. I believe i could have achieved at least another 5C drop if i upgraded the heatsinks and used some good thermal compound like arctic silver. Bare in mind that i had no components overclocked except my old ati 9200, and my whole system doesn't compare to the more modern builds where the components run even hotter and with the addition of overclocking there are some high temperatures to face. I think even with a top of the line rig that is overclocked it should be able to run it well under the recommended max temp of each component.
To explain whats going on here i removed the face of my tower and used tape to cover as many places air could flow to draw as much through the hose as possible. The other end of the hose is ran through some foam and out a window, foam was used to insulate the rest of the opening in the window. The little door in the cardboard was made so when the hose is not in use i could open the door to relieve some stress on the fans. I recently added a cut out in the tape for my HDD since it was in a dead spot of air and they warmed up pretty good. Used to have them in front of the intake fan but moved them up for better air flow.
