Way back in the days of the Pentium3 500MHz processors passive cooling was the only cooling around but the advent of active cooling(fans ect) was dawning. Back then ppl poo-pooed passive cooling in favour of active, in fact active cooling became the way to go. However when I did some research recently for cooling solutions for my evga 680i mobo I read a lot of ppl reccommending passive solutions over active. I know there are solutions that incorporate both active and passive but these are not always suitable given space concerns ect. What do you guys think can passive cooling be as good as active.
