Test System & Test Results
TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
Load results with the NH-C12P SE14 were great. For what I consider a smaller cooler, it does its job with no complaints. The idle temperature is a bit warmer than usual, but as you slow the 140mm down as PWM settings would, the air flow is reduced, so the results aren't out of acceptability.
Another reason I love my Noctua I use every day, the noise levels I don't have to hear. At idle it's hard to hear with an ear within a few inches. At full on power there is a bit of a noticeable noise, but I test open aired and once in a case, the noise is covered by the PSU fan.
