My blowhole was just cut in my case right next to where the intake fan from psu is. I've seen a pretty decent drop in temps with it installed... it makes sure that all the hot air floating around up top - that the psu intake fan can't take care of - is moved outside of my case instead of going back down to the naughty parts.
(still chuckling from Him's sexual inuendo statement.. tee hee)
