In this review Frostytech is testing out Noctua's new NH-C12P heatsink. The NH-C12P comes bundled with Noctua's 120mm NF-P12 fan. Tower heatsinks may offer the best performance of any heatsink style, but many computer cases can't accommodate +140mm CPU cooler heights. 'Down exhaust' or 'impingment' heatsinks are so named because the fan blows downward. The overhanging portion of this heatsink has the added advantage of cooling devices adjacent to the CPU socket too.
