My blue box has like six fans. It sounds like a jet engine when I turn it on. It was the system that got to hot and fried its CPU, HD, and MB. When it fried the CPU that was expensive back in the day when it was built. $400.00 for a 1.4 gig AMD. (X 2) The HD was just bad to begin with, damn Western Digitals don't hold up well to heat at all. The MB was a flawed ASUS made with inferior Chinese's chips.
I don't use it much any more as it is so very loud and it was build in 2001 and sports a $500.00 GeForce 3 card. You know the card that they released that was pretty much outdated the moment it was put into a box for sale.
The sound card went bad, or perhaps its conflicting with the on board sound card, I am not sure, but it doesn't have any sound.
I think having a cool room to run your PC from is better than having extra fans. If the room is hot, then the air being sucked into your PC is also hot. No real cooling going on. What they need to do is sell small PC AC systems.
