Noctua have always payed attention to the littlest of details,
and what we just saw was no exception. The cooler performed greatly,
reaching first positions in the toughest of tests. At the same time
the design allows it to fit in smaller cases (unlike coolers like the
Cooler Master Hyper Z600 and the Noctua NH-U12P with which we compared
it) and it weighs only little more than a pound, which is a safe load
for your motherboard.
