cab cooling fan

<< < (3/4) > >>

shmokes:
I would personally get two fans (spend $30-$40 to get two good quality 120mm fans to keep your cab from sounding like a vacuum cleaner).  Put one at the bottom of the case sucking cool air into the case and one higher up blowing air out of the case.

Ideally the fan that sucks cool air in will be at the bottom and the one blowing warm air out will be at the top, above the monitor.  Your monitor is at very high risk of overheating.  Just because it doesn't monitor itself and give you a warning the way your PC does, does not mean that it does not get very hot.  Your monitor WILL burn out if you do not give it adequate ventillation.  My picture shows a very inefficient system you could set up easily and would probably solve your problem.  It's inefficient because the fans are so close to eachother that  a lot of the air that gets blown out will be nice cool air that just got sucked in.  If you can manage to hide the intake fan on the front of your cab or move the exhaust fan to the top of the cab (or both) you will have the best setup, but if not, the setup shown in the picture will probably solve your PC overheating problem.  

Don't forget about the monitor, though.

Heat rises.  Take advantage of that.   I'd do your monitor shelf holes (I didn't exactly understand what you said, but...), and then install a grill at the very top of the cabinet to let heat out.  Then make sure there is some way for air to get in at the very bottom.   A slot in the back will work if you can't find anything else.

Place your monitor shelf holes strategically, right over the parts you expect to get the hotest, the heat will rise from there, and pull more air in, right over the hot parts.

I just realized you were talking about AMBIENT temperature.
I think that's going to call for some pretty drastic measures.

You might consider putting the sides back on the case, and working on a snorkel system for the computer.

That will get you air from outside the cabinet, and get rid of the air directly, rather than filtering it through the cabinet.

This is actually not a bad idea.  I was thinking about doing this myself.  Just go down to your local homedepot and get some dryer vent tube and run that to wherever the fans are located on your case and the other end to a grill in the back of the cab.

Don't forget the Duct Tape.

See sig for details.  ;D
