I was thinking... Why let my CPU heat the rest of my case? What If I put a pipe around my CPU and let the heatsink fan blow it down the pipe? Heck I'll put an extra fan on the end of the pipe and let it suck the air that the heatsink blows and help push it out the case. Fortuantly for me, my setup is suck that noise isn't an issue. Any thoughts on this? The picture is a poor attempt to show it. Preliminary testing looks positive...
I hope I'm not off-topic...

For the past few days I was thinking of using the AC 6" bathroom ventilating fan on the glass window to suck air from the heat-sink. A plastic funnel will be needed to cover the front side (intake) of the ventilating fan then a flex tube (60~80mm diameter) will be connected to the duct (like the one in the above diagram but it will not have the 80mm fan and the duct will be TIGHTLY connected to the heatsink w/o the 60mm fan). I suppose the air-flow of such ventilating fan will equate the cooling effects of H2O cooling...but some what more compact
Hey EB are you sure your Hsf blows out and not on the heatsink? Most blow on the HS and exhausts out the side. Your diagram would still be sucking in your warm case air. Flip your arrows and you're golden.
