PC Cooling

Matt is an avid gamer and overclocker hailing from Australia, He has been messing around with PC's since he was 12 years old. When he's not he is usually lurking around twitter or online forums.

Noctua has been around since 2005 and are world renown for silence, quality and class-leading performance, today we are to take a look at the successor to the NH-D14, The all-new NH-D15 has had several tweaks and enhancements made to ensure it can compete with the best of the best air coolers out there.

Some of the improvements made over the old NH-D14 are:

Two NF-A15 fans are among the best 140mm fans on the market producing 140.2 M³/h of airflow at 1500 rpm.
The fin stack has been widened from 140mm to 150mm to allow for more uniform heat distribution over the larger area
The recessed lower fins allow for taller memory heat sinks making it compatible with the majority of RAM kits on the market (in single fan mode)

What has been carried over is:

Excellent component cooling thanks to the large NF-A15 fans providing airflow over the motherboard components
The very easy to use SecuFirm2 Mounting system which covers all

Noctua’s own NT-H1 Thermal Compound ranks among the best in the world and requires little “burn-in time”.
The PWM support allows you to either control the fan speed through your motherboard or limit them from 1500rpm to 1200rpm with the supplied Low-Noise adapters

All in all this is a very impressive cooler on paper so let’s see how that translates into the real world shall we?

I would like to thank Noctua for sending us the NH-D15 for testing and review.

Noctua NH-D15 Unboxing

The box is very simple and understated – just features the stand out specs for this cooler such as the 140mm NF-A15 fans, the low noise adapters and a promise to past and future socket compatibility (if technically possible)

The back of the box gives us all of the new and improved features that the NH-D15 has to offer such as the elevated fins to allow tall ram (in single fan mode), the SecuFirm2 mounting system and a huge 6-year warranty on the NF-A15 140mm fans.

The side shows us all the important specs of the heat sink and fans along with a dimension overview showing us just how big this monster is.

Inside we see that everything is in separate boxes and not little plastic bags as is the norm, This gives this cooler a premium feel even before you take it out of the box.

Here we have the mounting kits for both AMD and Intel as well as the accessories box.

Underneath we find the heat sink and second fan both enclosed in sturdy cardboard boxes and enclosed in foam, This is really nice packaging.

Each of the mounting kits have their own extensive manual for installation with the kit for AMD using the stock back plate it requires fewer parts.

This is what’s in the accessories box pictured earlier, We have the installation kit for the second NF-A15 fan, two low noise adaptors (7v, fully sleeved)), Noctua’s long reach screwdriver, a 2 into 1 PWM adaptor (fully sleeved) and an all-metal Noctua case badge which adds to the premium feel.

From the moment you take this heatsink out of the box you know that Noctua are not messing around.

This has 6 nickel-plated copper heat pipes between the two towers and we can see the cutouts to allow for high-profile ram if you only use a single fan, the heat sink itself feels very solid and you can drop the fan in the middle low enough to allow for airflow over your motherboards vrms which is quite handy when you start overclocking.

There are no blemishes, dents or scratches at all on this heat sink all of which points to excellent quality control.

This is exactly the kind of mirror finish we all like to see on any cooler and massive kudos to Noctua for providing it.

Here are the NF-A15 fans in the almost famous brown and cream colour scheme but we can forgive them for that because of the performance they provide:

Pushing out 140 cubic metres of air per hour is quite impressive considering the noise levels only hit 24.6 dBa

Since this uses the stock AMD backplate mounting and installation needed prior to the heatsink is fairly straight forward, just a couple of screws to hold the brackets on and that’s it.

Then it’s just a case of using the long-handled screwdriver provided to secure the heatsink to the brackets.

And here we are fully mounted and assembled

I have to say that this is really quite an easy cooler to install, fairly straight forward with the only issues being the sheer size of the heatsink meaning it’s best if you lay your case on its side and remove the GPU to make it all go a bit smoother.

I’ll be testing this cooler using Asus ROG Realbench with various CPU clock speeds and with the fans set on standard and turbo, Ambient temperature is 23c.

Testing Rig:

  • CPU: FX-8350
  • Motherboard: Asus ROG Crosshair V Formula
  • Memory: 16GB AMD R9 Gamer Series 2400Mhz 11-12-12-31
  • Graphics Card: XFX R9 290x DD
  • Case: Cooler Master HAF Stacker 935
  • PSU: Silverstone Strider Gold Evolution 1200w
  • TIM: Gelid GC-Extreme

Here are the clock speed and voltages used on this CPU to test out the cooler.

At the stock fan profile this cooler does very well to keep the temps down while remain near silent even at 4.8Ghz

With the turbo fan profile we see a small drop in temps and this tells me that the cooler is already working at near peak efficiency.

These readings were recorded at 30cm away from the case and this is fairly impressive, hitting a max of 41 DBa in it’s Turbo profile.

The upsides to the NH-D15 are a plenty, For its size, it’s easy to install, It oozes quality, provides great cooling and its noise levels are very very good.

The downsides are very few for me, the colour choice of the fans aren’t the most pretty out there (but there is no doubt they are Noctua’s) and that’s it.

Overall I am very impressed by the NH-D15, it’s a premium quality product that performs very well, looks great, is very quiet to run, has some very easy mounting options
And it even gives AIO’s a run for their money while not being priced over the top.

Noctua NH-D15
Review Summary

The NH-D15 is a premium quality CPU cooler that shows Noctua is still setting the bar for high end air cooling.

    Bought this Cooler soon after it was released. Have to admit, I am a bit of a Noctua fan due to the super-high standard of their products, continued after sales support and top customer service. Everything about them is quality.
    Currently running my NOCTUA NH-D15 on an AMD FX8350 with an Asus Sabretooth 990FX R2.0. The 8350 is overclocked to a stable 4.5GHz at 1.428v – running P95 Blend for 2 hours, the max temp never goes over 53 C.
    Highly recommend..

      Great to hear!

      I have to admit i found it hard to believe this cooler worked so well but manages to stay very quiet at the same time, Impressive stuff for sure 🙂
