I'm gonna run it out the window and pipe cold outside air directly into my x850) I hope I don't run into a moisture problem Anyone ever tried such a thing? I saw a youtube video yesterday with an air conditioner piped directly into the cpu and vid card.

Don't do it without prepping your system for condensation. If your room temps are... say 24C and the outdoor temp is 18C. Condensation would form on your metal components once they hit 18C if humidity hit 70%. Then bye-bye components. Also, a 120mm fan may not be powerful enough to pull a sufficient amount of air to make it worth the effort. One final thing... 12 feet is a long way. That's allows plenty of time for your room temps to warm up the air in the tube.
Once again...

How would I go about prepping for condensation? The humidity level in this room is 31% right now..I doubt ever goes above 40%, as I don't keep it very warm in general and I don't use a humidifier. Thanks for the advice about the humidity.

Hi ny driver,

As to your first question about the A/C. I did that this summer. Took a 4" diameter dryer hose (Alum) and ran it from the 2 x 10 floor duct into the back side of the computer case. Pointed the duct as close as I could into the 120mm fan on the backside of my V-1200 Lian Li case. Dropped the temps about 5-10degC when the A/C was on. No problems with condensation.

As for the outside air into the back. I live in Michigan and outside temps are in the 30's at night, 40's in the daytime. I have an 80mm fan (Sunon 40cfm) against the window screen pulling air in from the outside and into the 4" ducting. The ducting run is about 5-6 ft. The temps dropped about 5-9degC. The room is also cooler, because the window is cracked open about 3" for the 80mm fan. The fan itself does not seem to put out as much flow through the duct as the A/C unit did. I don't have any condensation issues, because again the air flow is ducted to a 120mm rear fan. All temperature reading are with MBM5. I'll have to see what happens when the West winds kick up and help blow cooler air into the ducting and house.

BTW - I wear long underwear in the room. Room temps are around 18-19degC or 64-66degF.

I hope this helped, :-)

yes, very helpful, thank you) I keep it about the same temperature in here. I gtg get my uncle to torch a hole in the side of case for the new 120 mm exhaust fan. I'm gonna put it right across from cpu. I have a front and rear 80 mm intake I will try to pipe in cold air through both. I put 1 of the 80 mm intakes below the video card ..in all the empty slots. i'll keep you posted.

hehe we chiseled a circle and popped it out then I filed it good) I think the new fan configuration only dropped me a few degrees but now the case is closed up....update..both of my video card temps are running 4 degrees lower at idle., system and cpu dropped 3 degreees at idle but the HD temp dropped 8 degrees. pretty decent I guess...now to see if she got any faster with the new crucial ballistix 2x512 ddr400)
