The reviewer doesn't believe in complete passive cooling, and used it with a blazing hot 100W APU despite Nofan's 80W limit, but the brave little cooler still passed the test.
"The CR-80EH is something the others aren't, it is truly silent. If you're planning on buying this for a low power dorm room, bedroom, HTPC or home server build you're going to have to be very selective about which case and hardware you pair it with, but in doing so, and if chosen well you could very well end up building yourself one of the quietest systems around. The market is niche, but it is there, and the CR-80EH slots in nicely. Silence may well be Golden, but it's also Copper."
