Cab Cooling
Silverwind:
I just bought a boatload of fans from newegg..
http://www.newegg.com/Product/Product.asp?Item=N82E16835150044
if you buy 10+ they are 1.69 each with free shipping. 80mm 12vdc pc case fans. I plan to get a variable fan speed control to slow them down if they are too noisy.
TimmyB:
I am with RayB, something else besides cabinet air circulation may be the problem. CPU Fan mounted the wrong direction, inadaquete CPU heatsink, lack of good contact between heatsink & CPU are all likely suspects. I strongly recommend an aftermarket CPU heatsink (Zalman, etc) and aftermarket paste (artic silver).
PaulG:
RayB may be correct about something being incorrectly mounted, but I'd stop short of making declarative statements. What exactly is the temperature/humitdity outside?
I'm always annoyed (Not speaking to anyone here, just the internet in general) when people go banting about how cool their computer/case is and they give some absurdly rediculious temperature they're operating at. I do the farenheit-celcius coversion and realize that temperature is at/below normal air temperature. My thought becomes: Where the heck do you live? Alaska? I live in southern Florida and I have numerous fans (And quality at that) for the fall/spring when it's not really hot enough to turn the air on, but don't wanna kill the computers because of it. In the winter when a cold front comes through, I get the insanely cool CPU temps too. But without air temperature numbers, cpu temperature figures are useless.
If it's 95 and humid (And he doesn't have air), not having any fans in that hot box is gonna cause problems.

Point taken.

Some things:
When using ducts, make sure not to make them very long, because the duct itself puts a resistance on the airflow and your fan will loose function because of that.
However, my guess is that it won't be neccesasy to use ducts...
The coolling of a cab is based on the chimney effect. There should be openings in the bottom to let in air and near the top to let if flow out. So be sure that there's no blocking of that air flow.
Do you have your PC closed inside the cab ? May I ask why ? Remove the cover !
It's already in a casing(the cab !!) so why need another computer case ?
My Jamma cab had a horizontal slide-in board to mount the original game PCB's.
I have installed my PC components directly on that board, best cooling you van get :)

(looks a little messy on this pic, but the DVD-drive is there only for installing, and there's some more loose parts still...
