If there is one thing I am starting to get good at, it is ghetto style mods that cost next to nothing (and have a 50/50 chance of working). Well this seems like it works. I'll let the pictures speak for them selves on what it is. The blower is from an 8ft inflatable scarecrow that I got for 5$ on clearance (kind of like the big 8ft inflatable santa clauses people put in their yards). The pipe is a dryer vent hose. The hose actually fit perfect on the blower and matched up perfect with an 80mm fan mount.
So now for the vortex. The blower blows quite strong right out of the front of it (you can feel it on your hand 2 feet away). With the pipe hooked up (the pipe expands from 2.5ft length to up to 8 ft and is spiral in design), there is almost no air even 6 inches from the end of the pipe. You can stick your hand into the center of the pipe (hose) and there is a complete dead spot (no air movment). . You can feel air around the edge of the hose but it doesn't feel like much, even inches away, till you actually just about touch it, but when you get that close and almost cover the end with your hand, you can then defanatlly feel the air and the preasure (I think it is coming out with reduced air volume but increased preasure). The air seems to be coming out sidways around the edge of the hose like the spiral design of the hose has made the air vortex. I figured that it might give beter air distribution but might reduce actual cfm of air flow. I know that the case gets air when it is hooked up, because you can place your hand anywhere in front of the case and feel a draft (air blowing out every vent and crack in the front of the case). Cpu temps drop about 8-10c with the fan on (compared to it off and no fan at all 52c max without to 39c minimum though some was with minor load, some wasn't, I am pretty certain I'm getting at least 8-10c). This particular motherboard only reports cpu temp (the blower will eventually go on my other overclocked computer but this one was easier to test it on).
Any thoughts on the way the the air is vortexing? Should I try to get a diffrent kind of hose that doesn't do that?
