WellAny recent ATI and/or nVidia card has its own fan and massive heat sink attached.
Actually, there are very capable cards available with passive heat sinks for Home Theatre PC applications (e.g. http://www.evga.com/products/moreinfo.asp?pn=256-P2-N549-TR&family=22)
And the cards, alone, will drown out any reasonable conversation you're trying to have.
I have an Nvidia Quadro FX 3450 in my octo-box - and it screams *up until the time* that the graphics driver is loaded. From there on, the fan is hard to hear even with the cover off the box.
Of course, heavy 3D work or a hot room will make it spin faster - but that's true of any laptop or PC.
Call it what you want. It's not an engineering failure. It's called a TRADE OFF. When you become an engineer, you can learn about those. ;-)
I'd call it a "fashion tragedy" - when the style requirement for "thin" gets in the way of the engineering needed to support the components.
"Engineering failure" due to fashion requirements.
