Default PC cooling advice?? - Please

I am building a new pc now and I need some cooling advice. I have two 80 mm fans in the front of the case, and a 92mm in the MB side towards the front as intakes, and I have 3 80mm exhaust fans in the rear. My question is I also have a 92mm that will be going into the rear of the side door as soon as the fan arives, it will be almost over the video card, should I have it as exhaust like the 3 80mm or as an additional intake. I am going to be running the FX5200, and a hot athlon 64. What should I do here?

One additional question, one of the 92mm is temp controlled and one is not, where to you think the temp controlled one shoud be, front intake or rear whatever?

You want as much exhaust as possible. it'* a small volume in there, so pushing more air in doesn't do as much good as you'd want to think. You want to suck the heat and dust out. And the temp controlled one is definitely an exhaust fan.

Negative pressure is better then postive pressure in some cases (towers), but the key thing is air flow. Hide your cables behind the Mobo tray, and the Drive bays. So they go behind them, and pop out right by the component. Have a case that has good inlets in the front, and 2 fans in the back, and one on top as a blow hole. Fan bus controllers are nice too. But anything more then 5-6 fans is too much, and too turbulent.

agreeded and do make sure to filter at least the intake fans to limit your dust with that many you'd get allot of dust quickly as with the 64'* I woudlnt want to spend the money on the "special" microsoft os to run it efferently

That'* overkill. Great advice. PULL the air through. More pull than push. And mount the thermostat fan at the exhaust, at the highest position. Heat rises. It'll sense the hottest air that way.

Try for twice as much pull as push. Even (especially) if you have to ditch some of those fans.

Instead of hiding the cables behind the tray (and possibly damaging them), get cable wraps. They are similar to wire looms that you use in the engine bay. Wrapping the cables will consolidate the bundles and they will all be round instead of flat to allow more air flow. Most PC shops are starting to carry these. This way you can still easily access cables for swapping and maintenance.

The case I have has a built in filter on the intakes. Also this case was built to hold 4 80mm fans and 2 92mm fans plus the PS fans. Nothing was custom. As for the Alton 64, I am buying it for many reasons. One is it can run both 32 and 64 bit applications together, so theres no need to upgrade my os. Another reason is it has and internal memory controller that does away with the old style FSB. The internal FSB is 1600MHz. It also has many other features , like the 1MB L2 cache ( on the 3200+ models and up). For $282 is a great buy.

As for the 2nd 92mm I will take your advice and use the temp controlled on in the back side of the case and set it up as exhaust. Thanks Guys

There'* no need for 64 bit computing for a while. People say it'll speed up computing, but the consumer has no use for 64 bit processing. The best thing that could happen to us right now is software elegancy.
