Looking at the chart above, we can see that the NH-C14S with one fan is about one Celsius cooler than the old

Compared to the original NH-C14, the layout of the NH-C14S has been offset in two axis. Thanks to this measure, the heatsink will clear the top PCIe slot on most micro-ATX and ATX motherboards when the bendings of the heatpipes face the PCIe slots or the I/O panel. NF-A14140mm premium fan There's a 2-3 Celsius margin of error when measuring the temperature so most likely there is zero difference between the NH-C14S and NH-C14 in idle. need 1.30 volts to get the 3770K stable at 4.6Ghz but I'm doing this to stress test the cooler to its limits. You can easily get What's special about this cooler, is that it mounts sideways. This means that most PC cases can fit it. In fact, your graphics card is likely to be higher than the cooler, even in the "fan on top" configuration. Secondly, you have the choice of two configurations with the fan. Fan underneath is applicable for mini/micro ATX builds. Fan on top is suited towards regular PC cases. Each test run was 60 minutes in duration. The last 50 minutes of each run was measured, and the temperature logs were analyzed in Open Office spreadsheets. An Intel chip reports its temps in one degree increments, so for best accuracy these reports should be averaged in aggregate. Here the core temps were measured once a second, resulting in 3000-line spreadsheets. The digital thermometer measuring air temp reported its measurements in increments of 0.1 °C. The ambient temperature was measured every five seconds, resulting in 600-line spreadsheets. The mean ambient temp was subtracted from the mean core temps, resulting in a net temp for each run. The net temps were then averaged.The NH-C14S comes with one 140mm NF-A14 PWM fan but Noctua has sent us an extra NF-A14 PWM fan to test with both one and two fan configuration. The NH-C14S comes with one 140mm fan while the old NH-C14 had two 140mm fans with a maximum RPM of 1200. Noctua has an outstanding customer service so if the fan ever stops working, they will send you a new one for free.

We will measure the noise levels for both in idle and load using a dBA meter and point it at the computer at a distance of ~50 CM. Taking what was a very decent cooler originally, rethinking it from top to bottom by restructuring and bracing it, a new fin design and density, and with only one fan shipped with this version, you have the choice of how you want to cool your system, and it also offers a cooler that can go from full-tower cases down into Micro-ATX towers and even some SFF designs. In the chart below we have sorted each CPU cooler from highest to lowest by the fan size in millimeters.

Noctua is well known for its superb heatsinks and fans. You might say we are blown away by their products. This time around, they have modified their well-proven NH-C14. This is a blown-down heatsink. Why use a blow-down heatsink? You may have noted that some these heatsinks blow air directly on your RAM and or VRMs, cooling it. That’s one reason. But probably the most common reason is to use a narrower case. Hold onto your receipts. From my own interactions with customer support and the interactions of others, I can tell you that Noctua provides world class support to their customers.

it stable with using ~1.25 volts and you will probably get much better temperatures than I did so keep that in mind. Physical Attributes In the chart below we have sorted each CPU cooler from highest to lowest by the maximum amount of airflow they move in CFM.

The NH-C14S performs great with just one fan and it is whisper quiet just what you would expect from a Noctua product. Inside you will find Noctua's NT-H1 thermal compound, one Low-Noise-Adapters (L.N.A) which can be used to reduce the fan speed, I was a slightly concerned about this fitting with the fan on the TOP of the cooler and still being able to fit in my Hyte Revolt 3 case. It turns out that it fits perfectly. To the millimeter.
