A few days ago we took a look at a "Special Edition" cooler from Noctua, the NH-U9B SE2 (full review can be found here). The NH-U9B SE2 took an existing Noctua cooler and added another fan as well as added support for newer CPU sockets that the original did not support. In our testing we found that even though the cooler had been around for a couple years it was still able to keep our test machine running at decent temperatures.

Today we are going to look at another "Special Edition" from Noctua, this time it's the NH-C12P SE14 CPU cooler that we will be testing. Much like the NH-U9B SE2, the NH-C12P SE14 uses the exact same heatsink as the original cooler but this time instead of adding extra fans the folks at Noctua have included a bigger fan than the original by pairing this heatsink with the new Noctua NF-P14 14cm fan (our review of this fan can be found here). The NH-C12P SE14 also adds support for the new Intel CPU sockets which the original was lacking.

The Noctua NH-C12P SE14 cooler is a little bit different of a design that most of the other "heatpipe tower" coolers that we have seen in the past couple of years. The NH-C12P SE14 is designed for applications where space is limited by using a "C-Type" design which makes it suitable for small cases (HTPC, SFF).

In this review we won't go into as much detail as our original (our original review of the NH-C12P can be found here). If you want to take an even closer look at his cooler please refer to our original review.


First Impressions:

In this section I will give you a side-by-side comparison of the original NH-C12P cooler and the new improved NH-C12P SE14 cooler. Due to the lack of differences between the two coolers I'll try to keep this section nice and short.

Noctua has updated their packaging in the past couple years and now go with white boxes instead of the traditional brown Noctua boxes.

As you can see from the heatsink pictures, they are pretty much identical. The only difference is the new mounting bracket.

The biggest difference between the original and the new cooler is the fan. The original NH-C12P came with a 120mm Noctua fan while the NH-C12P SE14 comes with a bigger 140mm fan.

The original fan that was included with the NH-C12P cooler was capable of approximately 59.2 CFM (cubic feet per minute) of airflow while the new 140mm fan that comes with this cooler is capable of approximately 64.9 CFM which should give us a little better performance thanks to the increased airflow.

Installation is pretty much the same and is still very simple to get done (still requires motherboard removal to install the bracket onto the back of the motherboard). The Noctua NH-C12P SE14, just like the original NH-C12P, is able to fit into cases where other bigger heatsink might not be able to thanks to its unique design. Thanks to this design the cooler is able to go over top of components such as the RAM without interfering and also provides extra cooling for components near to the CPU socket.

Well that's about it for this comparison section, now you have picture proof that I'm not making up the fact that these coolers are very similar.

Noctua NH-U9B SE2 CPU Cooler - Testing:

For Intel (LGA1336) testing we will be using the Intel Core i7 920 CPU, which produces 130 Watts of heat. This could be considered a mid-range processor, and while most Dual-Core processors produce ~50-80 Watts of heat, this should give you a pretty accurate estimate of what type of temperatures a cooler will provide you with.

For both AMD and Intel testing, we have taken all temperatures using CoreTemp v.0.99.4. CoreTemp takes a temperature from the CPU core, and allows for much more uniform results across different motherboard and CPU platforms. These temperatures may seem higher than other temperature recordings; because chances are they are taking temperature recordings using the diode underneath the CPU, which isn't able to be as accurate, and can really fluctuate between different brands of motherboards.

For all tests we are using the Highspeed PC Top Deck Tech Station , and we are using no additional cooling in our testing. All temperatures are recorded in a controlled environment that is set to 23 degrees Celsius (73.4 Fahrenheit) to provide fair results between coolers.

For all tests we use Arctic Cooling MX-2 High-Performance Thermal Compound (Paste), We use the same thermal paste in all our testing so that we can keep our results consistent. If a cooler is shipped with thermal paste pre-applied, it will be removed and we will re-apply it with Arctic Cooling MX-2 to provide fair results.


Intel Test System:

For our testing of the Noctua NH-C12P SE14 cooler we have tested the cooler at full speed (1200 RPM) as well as with the U.L.N.A fan adapter that slows the fan down to 750 RPM. Included with the Noctua NH-C12P SE14 is another fan adapter that allows you to run the fan at 900 RPM (results not included in our charts).

At the slowest speeds the NH-C12P SE14 wasn't anything too amazing, however when you consider how slow the fan was spinning (which makes it extremely quiet) it's definitely acceptable for most people (and still a good 10+ degree performance increase over stock cooling). If your CPU is under 100 Watts chances are good that you'd be more than happy using the lowest fan speed settings.

Once we cranked the speed up to full we started to get some pretty decent results for a "lower" profile cooler like the NH-C12P SE14. From the lowest to the highest settings we gained an extra 5 degrees of performance while running our CPU at full loads. Even at full speeds the NH-C12P SE14 isn't a very noisy cooler and unless you have other "semi-silent" components chances are good you wouldn't be able to hear any fan noise over other system noise.

Now that we've seen what the NH-C12P SE14 can do let's compare it up against all of the other coolers we've tested.

There we go, the results are in and the NH-C12P SE14 has fared very well. While the NH-C12P SE14 isn't at the top of the results, it's definitely able to outperform other coolers that we tested, and in most cases is quite a bit shorter and able to fit into cases where some of the other can't.



Noctua NH-C12P SE14 CPU Cooler Final Thoughts:

It has been almost 2 years since we first took a look at the Noctua NH-C12P CPU Cooler (our original full review can be found here). While the Noctua Noctua NH-C12P SE14 might not be all that different from the original, it has shown in our testing that much like the original it was able to keep up with the others and offer great performance. The biggest difference between the original NH-C12P and the new Noctua NH-C12P SE14 is the size of the fan and thanks to the bigger fan Noctua is able to increase airflow by just under 10% which helps increase the performance of the Noctua NH-C12P SE14 over the original.

Quality-wise the Noctua NH-C12P SE14 is top notch, you're not going to bend fins on the heatsink during installation. Installation is also a breeze (although you will have to remove your motherboard to install the back bracket) and should take no more than 10-15 minutes from start to finish. As far as noise goes, the Noctua NH-C12P SE14 is very quiet and is very well suited for HTPC cases where you don't want to hear a fan spinning up and down while you're trying to watch a movie, even at full speeds the NH-C12P SE14 is tough to hear over other system noise.

It's very easy to like the new Noctua NH-C12P SE14 overall thanks to the high quality heatsink, low fan noise, and very decent performance. Thanks to those facts we've awarded the Noctua NH-C12P SE14 with our "Editor's Choice - Gold" award. If you need a cooler to fit into a tight case where others can't, then the Noctua NH-C12P SE14 might just be the cooler for you.


  • Good Performance
  • Easy Installation
  • High Quality Construction
  • More airflow than original
  • Able to fit into cases where bigger cooler can't



  • Nothing Major
