Case Fan Direction
Case Fan Direction
Is the fan on the side supposed to blow into the case or out?
It's your choice. Fans at the front blow in. Fans at the back blow out. If you have a two-slot rear-exhausting graphics card (like a GeForce 7800), you may want to have a side fan duct fresh air in. Otherwise, you may want to have it duct hot air out in order to prevent hot air from the graphics card from passing over the CPU on its way out.

Case Fan Direction
this coupled with a larger than normal low rpm fan would be one very quiet set-up dont you think?

Thanks!
A PC I built for a kid is apparently promptly shutting off once in a while, like once per 2 weeks. I asked if it was during hard use and he said yes.
The case seems well ventilated, so I am suprised. If I get him on the phone, I'll suggest he load folding at home and see if 100% CPU duty cycle can increase the problem or not.
Currently my theories are:
Virus
some kind of MoBo temp wire not attached right
some kind of Cool/Quiet Driver not installed
Some App is not playing nice with windows
It's not overclocked and it's a good case; the heat sink is on right and running, so I don't really think direct cooling is the issue. Maybe the Main Power Supply (Antec) has a wire loose?
My other PC freezes essentially never.

The most likely culprit for the situation you describe is a failing, ailing, or just plain insufficient power supply.
My present computer's second power supply, an Antec 550 (that I had to buy to power my 6800 Ultra), was failing to deliver sufficient voltage on the +5v rail, resulting in a computer that was A-OK to POST, and usually made it into windows, but hard-locked and had errors constantly.
Check the voltage monitors in your BIOS, or run a voltage monitoring tool in Windows as you perform HDD activity. If one of the rails drops, you've found the culprit.

what hexetic said... if the psu is NOT QUITE powerful enough you can get random power loss on heavy loads.
of course it can happen due to over heating... also saw a similar situation when the motherboard was shorting on the case (the guy who put it together missed just didn't think the risers were necessary). can also happen if the computer just plain doesnt like you.
