Top product class performance!

I have the Noctua NH-C12P SE14 CPU cooler installed on a Sun 1156 ASrock P55, CPU i5 661 4x3,3 Ghz and 16 GB RAM ADATA 1666 Mhz. I wanted the full load 80 degrees C. glad Intel boxed coolers Fans finally get rid of, which also begins to buzz unpleasantly. Installation of the Noctua cooler took about 20 minutes (I had to remove the motherboard to get to the backplate) and was graphically described well (except for the insertion of the two mounting bracket) on the detailed user guide.
An all crucial selling point for me was the design, because only with a blow-down fan the voltage transformers are cooled around the The (processor) tidy with a continuous flow of air, thus allowing you to overclock the motherboard at acceptable temperatures. The 14cm fan must somehow be accommodated, so is the cooling block, depending on the installation direction on the RAM module and cools it with the same. Much more than the finger width of a little finger is not more space between the work and save the block. Quite different in height: even in my Bigtower with screwed Airflowkanal on the side inner wall (on the CPU) fits this cooler / fan light in! Class, when compared with the monsters from other manufacturers.
The temperatures are now 33 degrees C. in idle with UltraLowNoiseAdapter and 26 without rotation down rotating (and noise-reducing) adapter. In the slowest setting the fan in my opinion is just as loud / quiet as the boxed fan (no longer audible in 4 meters, but cools about 8 degrees C. better.
Under full load, the Noctua reached 57 degrees in CPU temperature (with UltraLowNoise adapter) and 51 degrees Celsius without! And that without any case fans. He can be heard, however, no matter what adapter, always with a slight rustling.
And here is yet another great advantage of Noctua: I can in 1 minute time regulate the power of the fan by interposing 2er possible adapter to the CPU fan connector and so determine performance and noise level itself Since it to only a 3pin connector. mainboard, the fan can not be operated with PWM, but only with 3 fixed revolutions: 1200/900/750 U / min depending on the adapter with a flow rate of 110.3 m³ / h, 83,7m³ / h or 71.2 m³ / h at 1,2Watt power and 12V operating voltage and thus 19dB-10dB noise.
(According to the manufacturer can Scattered motherboards that work with non-pulsed signals, the fan drive or infinitely)

Compared with its competitors, this cooler is here so much smaller, cools just as good as a Scythe Mugen 2 and just as quietly. Perhaps a shade louder than the Scythe, but which is much larger and heavier and exerts in the housing hanging excessive pressure on the motherboard.

I was the Noctua NH-C12P SE14 totally convinced from the outset. Because of its low height, its excellent and adjustable cooling capacity and its minimal noise, but especially because of its top design he gets from me 5 stars. Class!
