I was getting frustrated with ,my efforts to overclock my AMD Athlon 64 3000+. Even minor overclocking was to muck for my high volume termaltake 12 solid copper heatsink. I really didnt want to get a liquid cooled system, that would weigh a ton, and be expensive as hell. Looking out my window, and seeing frost gave me an idea. why i have an unlimited suppy of cooled air at my disposal! right ouside! So here are the latest updates of my project.

I just got back from a trash run in a LMTV. Our unit is closing dowen so they are getting rid of most everything. I found about 12 feet of dryer duct, and some heavy duty poster paper. i want to run the duct to window and mask off the rest with the paper.
FORSEEN PROBLEMS:
1.) The tempature in the duct is well, lower than the ambient of my room. this can lead to condensation on the outside of the duct. Solution Well im gonna wrap it in a towel i guess. or somethin.

2.) The cold air flowing into the case, is well cooling the surrounding components as well, this could lead to a problem if the cold air was suddenly shut off, say the duct came out of the window and fell inside, condensation would form almost instanly on components. Solution Tape the shit outa it i suppose, or make sure the humidity in my room is low.

Well tell me waht you think! I hope this is an informative project!

Taken during the pre install. The duct is actually not sealed at all, it is just hung out the window and the other end is near the Case CPU intake fan. It seems convection alone pulls cold air down the duct since the intake is on the lower end. After approx 2 minutes the CPU dropped from ~101F to about ~83F with a room temp of 92F and outside temp of approx ~54F

Well, to help with the condensation, I'd suggest that you have the duct rise up into the case. Meaning, put the case higher than the where the duct meets the window. This will make it so that any condensation forming inside the duct will be forced back outside.

I'd also suggest that you have some sort of a filter somewhere on that duct. Preferably where the duct meets the window so you don't get large amounts of dust, leaves, etc being blown into your computer.

But btw, nice BMW case you have there

well its night out and the test results are in. No condensation on the duct, i guess cause its like thin mylar, it tranfers geat well. before i hooke it up it was at ~98.7f now after like 5 minutes it now ~67f. no condensation unless im being goofy and breath on the duct... ill have MBM5 log the temps and make a graph about them.

you could try taping some insulation around the duct. it should keep the duct from condensing and th air in the duct cold. just a sugestion, don't bite my head off it can't be done. :\

once a warrior for the cause,
now shamed and disgraced,
banished from my world,
wingless i walk this one...
