@Paul - Cooling I'm building PCs for over a decade by myself and others too. In the last time, I'm using near passive cooling for all modells, at least thats my own goal. What could be seen in normal cases? First, when I use a normal Brisbane Core and near passive cooling (slow fan) the difference between a open and a closed case is over 10°C. Of course the temp with a open case is much lower. Also chipsets and other components go down in temp by a huge way, because the heat could "go out". When I compare my heatsink+fan in some different settings, you could easily reach 10-15°C temp difference as a addon under load. How? Rotating speed. My own fans normally run with 800-1500 UPM -> so they are near "quiet". But a normal AMD/Intel fan under 12V is not 1000, instead its 4000-5000 UPM and you could also go to DELTAs, which are up to 7000 or even more. You could easily cool that devise under these conditions in a much much better way. When I then go to 4 blowers in the case as an addon on, you could easily imagine, how much heat you could put out of the case fast. I haven't seen the case in detail, but from the picture it looked like: - CPU 1 fan - power supply - probably 2 fans - 3 GPU cards - each with 1 fan = 3 fans - case left = 4 big fans - case front = ? probably 1/2 fans - case over CPU = 1 fan So we come up with 12-13 FANs for that whole case. Do you see that picture? And now a person comes to me and says thats a "normal" desktop setting not overvolted - yes, sure. edit: Keep in mind, what a massive copper block with a fast fan can put away -> R600 card around 200W = 1 big fan BUGGI
