The Noctua NH-C12P SE14

Excellent CPU cooler, which has a large 14 cm fan that cools not only the CPU, but also the surrounding components on the motherboard. The package also includes adapters to adjust the fan speed and thus the noise. If you do not need full speed, you can have your computer very quiet. Delivery is also thermal compound Noctua NT-H1 and mounting components. Cooler uses six heatpipe tubes made of copper and aluminum ribs.
Heatpipe technology is based on the principle of a closed tube, where the "hot" end of the liquid with a low boiling point, which is heated and begins to evaporate in gaseous form rises to the "cold" end, where it condenses on the walls and the tube is returned in the liquid phase back. When heating the liquid is waste heat from the chip is used to change the state, and it then in the form of hot steam travels to the opposite end, which is necessary to cool to a temperature at which the vapor condenses. Compared to conventional convection heatpipe technology therefore offers higher heat transfer efficiency, but only if sufficient temperature difference between the two ends of the tube and its correct orientation. This cooler is compatible with Ivy Bridge processors.
