The case fans ran at the set 40 percent, while the PWM fans of the coolers ran at 100 percent. This is even more than the current flagship NH-D15, which gets by with six heatpipes. I run mine at 45-55% max.That’s not quite correct. On 100% RPM the fans perform the best. The heatsink has the dimensions of the 158x125x58mm without fans and 158x125x112mm with the fans. The NH-U14S, which cools almost identically or slightly better than the NH-U12A, is significantly quieter at 46.2 dB(A). The statistic function in the system stability test also shows the average values over time of the individual cores. The radiator is then screwed onto these brackets with only two spring-loaded screws. The cooler comes with a significantly thicker heat sink, which is supposed to offer 37 percent more surface area. Until then we have tested the brown version.The Noctua NH-U12A takes over the heritage of the NH-U12S. He is mainly responsible for the news and our social media channels. There is a sticker pasted on the axis hub. My i7-950 build finally bit the dust and i just ordered an i7-8700k My old system had a Noctua NH-U12P (4 heat pipe dual tower) My initail plan was to re-use this on the new build.. however im curious if there is any big advantage in upgrading to the newer Noctua NH-D15 … This cooler is compatible with leading sockets from both sides including Intel LGA 115x/20xx and AMD AM4/AMx/FMx. All of your findings are at basically 100% fan speed.The NF-A12 was designed to be most efficient between 40-60% rpm. The ambient temperature is deducted from this average value to yield delta temperature. Established in 2005, Noctua took international silent enthusiasts’ hearts by storm and quickly developed into one of the most acclaimed suppliers of premium quality quiet cooling products. The speed increased continuously up to 70 degrees Celsius, from then on the fans of the cooler ran at 100 percent.As a test program, we have again chosen Prime95 for this test. The fan does not overhang the RAM thanks to the asymmetrical or offset design of the heatsink.Following software were used for the testing and monitoring.The thermal paste being used on my test bench is the Noctua NT-H1 thermal paste. It is 1.2 degrees warmer without overclocking. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. The price of a NF-A12x25 PWM is $29.90. There is a groove or circular inset in the middle of the heatsink on both sides. As the name suggests this is a 120mm size cooler having a dimension of 158x125x112mm (HxWxD) with both fans but don’t let the size fool you. Already during the reporting to other coolers we have therefore read again and again as a comment that only the colour prevents many from buying.However, the color is one of Noctua’s success factors, as the company let us know upon request.
These are to indicate the direction of the airflow and the direction of the blades’ movement which helps the novice users in correct installation of the fans.The cooler has been tested on the Intel LGA2011(3) and AMD AM4 sockets using the Asus Rampage V Edition 10 and Asus Strix X470-F motherboards; Intel i7 6850k and Ryzen 7 2700X. However, since the blend test has not proved to be necessarily constant, we now perform the measurements with the Small FFTs test as a load. This is where it really gets interesting. Noctua is offering 6 years of warranty on this cooler.Coming to the fans, the Noctua has gone all out as they have bundled their next generation premium NF-A12x25 PWM 2x fans with cooler in push/pull configuration. Without overclocking, the lead shrinks to 2.2 degrees Celsius.Just how good the NF-A12x25 fans actually are can also be seen in the test with the NH-D15 and the two fans of the NH-U12A. Noctua’s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency.Noctua brand logo and name are embossed on one side of the fan’s frame.There are two small arrows on one of the frame’s side. Despite not having a dual-tower design like the NH-D15 does, the showcase at Computex 2019 proves that the NH-U12A is actually a very capable air cooler just like the NH-D15. and the Taiwanese cooling specialist Kolink International Corporation, pooling more than thirty years of experience in the development, manufacturing, and marketing of high-end cooling components. Each cooler in our test had to cool the i7-7700K at standard clocks of up to 4.5 GHz in automatic mode and overclocked to 4.8 GHz at 1.28 Volts.We finally measured the temperature with AIDA64 Extreme. SSO2 is the further optimised second generation of SSO. They could have increased the thermal performance by including NT-H2 in the box instead but that would have increased the already high priced tag of this cooler. The cooler comes bundled with the 3.5gm pack of Noctua’s premium NT-H1 thermal paste. The Noctua NH-U12A performs as well as some of the liquid AIO coolers we have tested. A twin tower cooler in 120 mm format with the NF-A12x25 fans would probably be unbeatable and would also outshine the NH-D15.We were somewhat disappointed by the volume of the fans in comparison.
Now, this price is a steep one. Here is the voltage and clock information for both platforms:On the Intel platform, I have been using the Asus RealBench software to stress test the CPU. The cooler is using the SecuFirm2 mounting system which is Noctua’s trademarked assembly hardware making it a standard on all of their coolers. Noctua originates from a collaboration between the Austrian Rascom Computer distribution Ges.m.b.H. On AMD platform, RealBench was problematic hence; I resorted to AIDA64 Extreme for CPU stress testing. With LNA, this speed is 1700 ±10% RPM. On the one hand, we tested the direct predecessor NH-U12S, on the other hand the NH-U14S as a 140 mm version and the NH-D15 as a flagship with two fans. However, this quality has its price. The NH-U12A is the latest version of their family of 120 mm-based single-tower CPU coolers, which are designed to offer a balance between performance, cost, complexity, and compatibility.
