We recently examined the Noctua NH-U12P and found it to be a very capable tower-styled cooler, posting some great results in an extremely quiet setup. Today we're testing its Noctua sibling, the NH-C12P, which offers a top-down design, with the same famous Noctua silent fan but a slimmer profile for those who may have a more cramped mid-tower case. We'll be installing the C12P on a Socket 1366 Core i7 processor to give a direct comparison between the cooling abilities of tower versus top-down. We'll also toss in a handful of other top coolers to see how the C12P performs. We have no doubts about Noctua's renowned reputation for silent computing products, so all that remains is to see if the C12P can keep an overclocked Core i7 monster under control.
