Wind Tunnel

[SneakyStuff]

Hey guys, I got to thinking the other day, a neat cooling idea. Get a cheapo case, cut out everything that isnt needed on the front of the case, and the back of the case and leave both of the sides completely sealed off, no fan holes, no nothing. The only thing on the back of the case should be where the mobo sticks out, leaving 2 gaping holes on the front and back. Next, get 2 o those GIANT square floor/window fans. Put one as an intake in front of the computer, and 1 in the rear as an exhaust. Use cardboard, or plastic sheets to make a sheathe for the fans, closing them off, making the comp into a wind tunnel. Anybody think that would make for some great cooling? I'm SO tempted to try it with a POS machien ive got laying around

would work, but cooling depends on how efficient your heatsinks are too. and after a certain point, more air doesn't do anything. u can't go below ambient ever.

and its been done b4 http://www.dansdata.com/hx45fan.htm
written long ago, but info is still generally good

if ur hardcore... get a plexi see through side for pc and then get a fog machine... watch that airflow

i do wonder how long normal room fans would last 24/7 though. dan used some industrial fan though i think

industrial blowers kick ass

Downfalls:

-Blowing air in at the temperature of your room will yeild at best the temperatures of your room.
-Instead of having fans that run off of your PSU, you now need to fill an entire surge protector for just one computer setup.
-The amount of space the fans have to blow into somewhat defeats the purpose of having such big fans. Even if the fan is 500cfm, you'd experience maybe 75-100cfm of it at best. Simple case fans can have the same effect.
-Noise... god the noise.
-You couldn't set anything on your desk without it being blown away.

Solutions:

Place industrial fan in your basement. Cut a hole in the floor, and route a duct up into your computer. Vent outside. In the winter, reverse industrial blower to suck air in from outside.

another alternate, use a peltier on the cpu, with the original setup

sounds like a weekend with a dremel tool and a small mig welder to me.

o man that'd be SO sweet, haha WOW think of the airflow! (and the dust )

Coolermaster CM Stacker. You probably can put at least 3x 120mm fans in it. Mod a 120mm blowhole for the top, and you should be set with 2x psus in the back along with that 120mm.
