Noctua NH-D14 Review

One of the system improvements one can make for his system is buying one aftermarket cooler for his CPU, in order to keep temperatures low and achieve better overclocking results. Today we are making the review of the Noctua NH-D14, a high-end CPU cooler.

NH-D14   6 heatpipe dual radiator design
Providing more surface area, better heat-distribution and superior airflow efficiency than conventional tower style heatsinks, the NH-D14’s six heatpipe dual radiator design was developed to provide ultimate quiet cooling performance in dual fan mode.

NH-D14   Dual NF-P14/NF-P12 fan setup
The NH-D14 sports a premium quality dual fan setup consisting of Noctua’s award-winning NF-P12 (120mm) and NF-P14 (140mm) fans, both of which feature Vortex-Control Notches, SCD technology and SSO-Bearings in order to achieve a perfect balance of performance and quietness.

NH-D14   Asymmetrical design for high compatibility
An asymmetrical design that gives more clearance towards the RAM slots ensures good compatibility despite of the cooler’s size. The NF-P12 fan can be moved upwards or left off in order to further improve compatibility.

NH-D14   Excellent component cooling
Hanging out at the bottom of the fin-stacks, the NF-P14 fan doesn’t only contribute to the NH-D14’s superb CPU cooling capabilities but also provides massive airflow over surrounding motherboard components and heatsinks, thus ensuring excellent component cooling performance.

SecuFirm   SecuFirm2™ multi-socket mounting system
Noctua’s enthusiast grade SecuFirm2™ multi-socket mounting provides broad socket compatibility (LGA1366, LGA1156, LGA775, AM2, AM2+ and AM3) and meets the highest demands in safety, contact pressure and ease-of-use.

NT-H1   NT-H1 thermal compound
Noctua’s much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.


A Closer Look

The Noctua NH-D14 comes in a wwhite box on which the cooler itself is illustrated and the main characteristics are stated. At the back side there is a more detailed explanation of the product’s features.

Inside the package you will find everything you will need regarding the cooler’s installation and operation. More specifically:

# 1x NF-P14 premium fan
# 1x NF-P12 premium fan
# 2x Ultra-Low-Noise Adaptor (U.L.N.A.)
# Y-Split Cable
# 4x Vibration-Compensators (for using NF-P12 as case fan)
# 4x Fan screws (for using NF-P12 as case fan)
# NT-H1 high-grade thermal compound
# SecuFirm2™ Mounting Kits
# Noctua Metal Case-Badge

As we can see, the cooler itself is quite big.

The heatsinks are also big. Generally, the cooler gives the impression that it is actually a high-end cooler.

Overall, the cooler is well-built and its structure is neat.

Although we would say it is not huge, it is quite big, thus some users may have problems installing it into the case.


Test Setup and Testing Procedures

The machine’s specs on which we tested the cooler are:

Processor: Intel Core i7 920
Motherboard: Asus P6X85D
RAM: 6 GB Mushkin 6-7-6-18
VGA: Gigabyte GTX480 1536MB
HDD: Velocity Raptor 150GB
PSU: Nexus 1000W
Case: Thermaltake Armor VA8003BWS
Operating System: Windows 7 64-bit

We ran temperatures tests in 4 system’s states:


  • Idle, default frequencies
  • Full load, default frequencies
  • Idle, i7 920 overclocked to 4GHz
  • Full load, i7 920 overclocked to 4GHz


We tested the NH-D14 against:

Prolimatech Megahalems

Thermalright True

Intel’s Stock Cooler

They are both coolers of the same price range and category, and the Intel stock cooler comes with the i7 bundle.



Temperature Test Results

1 17graph - Noctua NH-D14 Review

As we can see, it is a good start for the Noctua, as it provides the lowest CPU temperature in idle mode.

2 17nocnhd14loadstockgraph2 - Noctua NH-D14 Review

In default frequencies at system load, the Noctua is still the best performer, with the Prolimatech Megahalems and Thermalright True being quite close.

3 17graph4 - Noctua NH-D14 Review

Afterwards we decided to overclock the i7 920 to 4GHz. Noctua wins again, with the other 2 coolers being close and the Intel cooler not being able to keep up.

4 17graph17april - Noctua NH-D14 ReviewAt the last diagram, we see that Intel’s cooler is missing. That’s because under system load, the overclocked i7 overheated. Also in this test, the Noctua NH-D14 proved to be the most temperature efficient cooler.

To sum up, the Noctua NH-D14 proved to be the best performer, keeping the CPU cool under heavy conditions.
It is obvious that Noctua’s cooler is a solid suggestion for the power user who demands extra cooling in his system.



The Noctua NH-D14 proved to do what it promises in our whole test range. While it costs around 70 euros to buy, it is totally worth the money, especially for the user who wants to squeeze some extra power from his CPU.
It is true actually that it is quite big and may not fit in some cases, howerver we did not encounter any installation problems.


(+) Outstanding performance destroys competition
(+) Package contains everything you will possibly need


(-) Quite big in size, may not fit all cases


Thus, we give the Noctua NH-D14 a rating of 10/10 and our Editor’s Choice Award.
