The NB-eLoop X B14-P ARGB works in a range between 0 and 1500 RPM, thanks to PWM technology, generating a considerable static pressure of up to 2.310 mm H2O. However, it becomes absolutely impressive when looking at the airflow, i.e. the air flow rate. A remarkable 186 m³/h (109.47 cfm) at maximum are generated here despite the low speed range. At 12 Volt voltage and full speed the fan is still not louder than a maximum of 29.6 dB(A) - this is a remarkable achievement in the world of air cooling. Cable management, Decoupling and LightingFurthermore, the NB-eLoop has cable management: Only a very short 4-pin cable is attached to the fan itself, the length of which can be varied using two supplied adapter cables. Thanks to the choice of a polycarbonate material, in particular Makrolon, the chassis is also vibration dampened and additional dampeners are still included as standard. If you are looking for good 60mm and 40mm computer fans for PC cooling, DIY cooling, 3D Printers, and cooling other electronic devices then you are at the right place. Smaller 40mm and 60mm fans can have a wide range of applications just besides PC cooling. These smaller fans are rarely used for case cooling nowadays because all the computer cases use bigger case fans which are 120mm and 140mm fans. However, they can be used in a PC case for focused cooling or for cooling other components inside it. These fans can be used to cool down the Northbridge or motherboard chipset, NVMe or SATA / M.2 SSDs, VRMs, or maybe even RAM. You can also use these fans on your passively cooled graphics card or regular graphics card if it has been heating a lot and the factory-fitted fan is not performing well. FDB = Fluid Dynamic Bearing, a patented evolution of the sleeve bearing which causes the lubricating fluid to be recirculated within the bearing.
The fans will be introduced, first, individually with descriptions and pictures. Next we see their specifications as a group. Then we shall look at their actual performance by comparing them with each other. So let’s get started. PWM Fans Arctic Cooling is the lowest RPM achieved on the B12-PS which is above the rated minimum RPM of 400. The maximum speed of the fan comes to 1650 RPM. Rated maximum speed is 1500 RPM. The fan stops spinning below 5.0V. Minimum speed on B12-P was 300 RPM at 4.5V giving us 11.94 CFM. The maximum reported speed comes out to 2130RPM which is 130 RPM above the rated speed of 2000 RPM. Thermal TestingBelow you can find the best 40mm fans for computer cooling and for cooling other devices. These 40mm fans can also be used as replacement fans for various devices and components including Flex ATX PSU. 40mm Fans 12V Noctua NF-A4x10 FLX Fan PWM fans are used for lots of things now. A PWM fan can be used as a case fan, as a heatsink fan, or as a rad fan. AIO coolers simply expand the playing field for PWM fans. So I have collected twenty-four fans here for review in our 2016 case fan roundup.
The fans come in a cardboard box of white and light gray colors. The front side has a picture of the fan on the main section. iF product design award of the year 2013 is printed on the top left side. NB-eLoop is printed in the vertical layout on the right side. Originally the house label for Newegg, Rosewill does offer their products for sale in other places these days. They produce a bewildering variety of fans. Not so bewildering are the Hyperborea fans, in 12 cm and 14 cm sizes. These have relatively low speeds as if the makers were aiming at their being used for case fans, as well as on heatsinks and rads. The two units here were obtained retail. Rosewill Hyperborea 12cm San Ace As said before, the blades are a translucent blue and have a slightly bumpy texture to them. This seems odd for a fan as it will increase air turbulence and therefore noise. It could also prove fatal with trapping dust over long periods of operating; our testing will let us know. PWM fans can be used with PWM splitters, where they all get their power directly from the PSU while tghey get speed control from the motherboard. The Deepcool GF120 was a fine runner-up. Notice how much quieter the two winners were than their neighbors. They also pushed a lot more air through the restrictive rad than fans of similar unobstructed output. What made the Deepcool fan a runner-up and not one of the winners was the fact that it was a lot noisier than they were.

Testing was performed on the Microsoft Windows 10 x64 Professional edition build version 1709. Noctua NT-H1 thermal paste was used. The fans were put on 50% and 100% of their speed. The pump of the CLC was put on 100% of the speed. Asus RealBench v1.44 was used to stress test the CPU. RealTemp was used to monitor the temperatures. In our first testing we, try to validate the stated/rated airflow value by the manufacturer. The rated airflow value of B12-PS is 58.1 CFM at full speed. In my testing, the airflow value comes to the 64.25 CFM validating the rated airflow value. The rated airflow value for B12-P is 77.9 CFM. The tested value is 89.90 CFM.
An older fan among the Noctua lineup is the NF-P12 PWM. It was designed to have higher static pressure than the S12 line. It provides a middle ground between the higher static pressure of the NF-F12 and the airflow-focused NF-S12A. The SWiF2 120: Coolink produced a fan with a unique impeller. It has a bullet hub and eleven blades. It came with vibration isolators as well, in electric green. The specimen here was bought at retail. Coolink 120P Corsair The NB-eLoop fans mostly need 70-90% of a number of revolutions compared to the available low noise axial fans to produce a comparable cooling capacity and volume thanks to its aerodynamically optimized loop rotor. On the other hand, Cooler Master has brought out the Jet Flo fans, in 120 mm and 140 mm. They have a POM bearing, where a combination of oil and plastic lubricate this fan. Given that the POM, which is like Teflon, forms the mainstay of this bearing, it seems safe to use this on your rads. Jet Flo fans come with red, white, blue, or no LEDs. The six examples here were provided by Cooler Master.
I thought I would never do it again, but soon I expect to see non-PWM voltage-controlled 120mm fans for review. It seems that OEM's still make them.Well, I got my Noctua NF-S12A fans tested, with their various resistor wires. Next come the Scythe Slip Stream 120DB's, the San Ace 9S fans, and a variety of oldies but goodies. I really didn't know I had so many! The GlideStream PWM fan was supplied indirectly by Scythe when they provided the Ninja 4 for testing. The Glidestream has a 3-way switch, but the switch was left in H when the GlideStream was tested. SPL testing on a rad might be misleading because fans -- even when mounted on a rad -- can use the CFM box as a sounding board. I have thought about building a testing chamber out of something large and stiff, but I would have no place to put it . . . and there would still be no assurance that fans did not use it to make a sounding board. Think guitar or violin to get a notion.
Among computer enthusiasts, Scythe is a famous name. We have reviewed the Ninja 4 and the Fuma heatsinks here. We have also reviewed the Slip Stream DB fans here. Slip Stream and GlideStream fans focus on airflow, but they can push air through a rad. The Slip Stream PWM was part of a Mugen 2 that was bought retail. The Slip Stream DB fans were provided directly by Scythe. Only the PWM model is tested here. You may wish to compare the specifications to the results, so I placed the table near the chart. The first column identifies the fan. The second says what kind of bearing it has. The third column tells the current draw in amps. SP means Static Pressure, which is stated in mm H2O. The Deepcool UF120 has been around since 2009. It is still for sale. This fan’s claim to fame is its rubber coating which attenuates vibrations. Further, it comes with four silicon vibration isolators. I have used most vibration isolators, and these are the best kind. Other accessories include a PWM-style 12-volt power tap (a so-called Molex adapter) and wires that shunt 12 volts and 5 volts together to get you a 7 volt Molex adapter. Both the GF120 and the UF120 were supplied by Deepcool.
40mm Fans 5V
Noctua’s industrialPPC line also uses a 3-phase motor. Most motors you see have four poles inside. These have six. Fans come in a range of different sizes from 40mm all the way up to 220mm with the average PC chassis fan coming in two sizes including the 120mm and 140mm variant. Chassis Fans
