How is exhausting all heated air outside of the case a CON? This is a PRO if anything! I'm lost now.. Otherwise a pretty decent review. Thanks!

Nearly everyone agrees that hot air does not belong inside the computer case, heating up the processor and other components. We want the video card to exhaust the hot air outside the case, so everything stays cool and lasts longer.

"Cons:

- Fan exhausts all heated air outside of case"

It says - OUTSIDE of case.. that's why I was confused.

If this "We want the video card to exhaust the hot air outside the case, so everything stays cool and lasts longer." is the case, then why is it listed as con that's all...

I too, as an avid overclocker, agree and understand that hot air does not belong in the case, thank you.

Exactly one year later, and I'm making a typo correction. It now reads "Con - Fan exhausts all heated air back inside case"

Lol... still relevant, lots of people are still purchasing this card, including myself - two of them in crossfire can keep up with a 580 - and for less money and less wattage.

Thanks for the review and the clarification on the cons!

Hopefully my going overkill with case fans will help to negate this issue..
