Noctua NH-C14S Review


Noctua NH-C14S Testing:

Testing of the Noctua NH-C14S will be accomplished by installing the cooler into the test system case. Most systems are built and mounted into a sealed (relatively) chassis as opposed to a test bench, so this method will be used to generate the idle and load results to give a real world view as to the cooling performance from a system listed below. Of course, your results may vary by several degrees due to case design and ambient air temperature. The CPU load is generated by Prime 95 version 27.9 for a period of two hours, with a cooldown period of one hour after the computer has returned to an idle state. Real Temp 3.70 is used to log the temperatures with the highest and lowest averages across the four cores of the Core i7 4770K test CPU. Ambient temperatures are kept at 24 °C during the testing to minimize the effect of temperature variations. Each cooler is tested with the manufacturer supplied thermal compound as delivered.

Comparison Coolers:






Noctua coolers regularly deliver great performance, and my expectations are that the NH-C14S will be no different. The last top-flow style cooler from Noctua that I reviewed was the NH-L9x65 and it is a rather small cooler, focused on the HTPC market where a compact cooler is typically required and extreme cooling is not part of the design. The NH-C14S is much more suited for an application that will see a CPU with a high TDP, and overclocking will likely be on the menu.

So, onto the testing. After the cooler is installed, the power is turned on and I let things get up to operating temp. The idle temps come in at 28 °C, which is at the higer end of the test units, but this is only four degrees above ambient, so no problems here. After applying the load, the temp slowly creeps up to 70 °C, which again is not a bad full load temp. As for the overclock, the idle temp starts at 34 °C, which is also toward the higher end of the test units, but certainly not a bad number. Crank up the load and the temps max out at 76 °C, which is almost in the middle of the pack. And 76°C is only a few degrees from where some of the liquid coolers perform. The sound level coming from the fan at full speed was drowned out by the case fans. So, Noctua again delivers impressive numbers. And you also get the extra cooling benefit from the NF-A14 fan pushing the air over the motherboard components.
