Hmmm... could be really simple...

Wikipedia shows conversion chart:

http://en.wikipedia.org/wiki/Convers...heat_flow_rate
1 atmosphere-cubic foot per minute = 47.820 074 682 24 W

Which is probably close to 48 Watts.

But this is atm-cfm and not cfm hmm... not sure if that is same thing... but

for now I'll go with it

So (800 * 60) / 48 = 1000 CFM needed !

=D

Let's see if antec case is sufficient lol:

http://www.antec.com/pdf/manuals/1200_EN%20manual.pdf
It's about 240 CFM...

So there is no way that the antec 1200 case would be able to cool such a

system sufficiently.

Yes perhaps the graphics card would output a little bit of air as well...

but it's waaayyyy too little.

And this manual probably assumes at maximum operating fan speed... so let's

divide 240 by 2 is 120 CFM... and let's divide it one more time because of

dust is only 60 CFM.

Yeah...

Well it's pretty clear where this is going:

OVERHEAT DAMAGE !

=D
