[QUOTE="Owlsroost, post: 491887, member: 83973"] Putting on my electronics engineer's hat, please be careful with passive CPU cooling - the 'passive' heatsinks/coolers are designed to be used in cases that have forced airflow i.e. case fans (it's the same with passively cooled video cards). The idea with these passive coolers is that you can use larger, slower running case fans 'remote' from the coolers instead of smaller, noisier fans mounted directly on the coolers. It's quite difficult to remove 40-60 watts of heat from a small box while keeping the component temperatures below 70C - put a 60W light bulb in a ventilated metal box and see how hot the box gets inside...
