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. Remembering all of these caveats you should be able to make an intelligent decision on which PWM fans to get. Thanks for reading our case fan roundup. Let us know your favorite PWM fans in the comments below. Radiators for PC liquid cooling come in all sorts of sizes and configurations, from single 120mm radiators (one fan placement per side) all the way up to monstrous 560mm radiators. Other than choosing the correct size you need to ensure the fans offer high static pressure. 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.

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 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! To do this, both sets of fans were left running for one week in our test PC to see how audible they are during day to day activities and also how much dust would build up on the fan blades in this short time. Noctua’s industrialPPC line also uses a 3-phase motor. Most motors you see have four poles inside. These have six. As the blades are now sort of ending at the frame which is also rotating, the vortexes are dissolved. The second contributing factor is the use of the invariant magnetic bearing which is called NB-Nano SLI2 bearings as these bearings won’t contribute to the noise production. These bearings remind me of the magnetic levitation concept on the Corsair ML fans. I was not able to find specific information on these bearings. They are using NB-EKA P2 motor.

Noctua is a partnership between Rascom, an Austrian company, and Kolink International, a Taiwanese corporation. Noctua products are legendary, with heatsinks for enthusiasts and industry, and fans with diameters of 40 mm up through 140 mm, also for enthusiasts and industry. In this review, we are looking at a number of fans, two with Low Noise Adapters, which bring our total number of fan sets to 26. 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. 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.

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. 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. Conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection, Noctua’s industrialPPC (Protected Performance Cooling) line comprises ruggedized high-speed versions of the company’s award-winning retail models. 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 next column shows the nominal fan speed in RPM. The next to the last column tells you how much noise the fan makes, the Sound Pressure Level at 1 meter, stated in decibels with an A weighting (dBA) which is reasonably close to what you might hear. And finally, the last column shows the airflow the fan produces, stated in cubic feet per minute, or CFM.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. 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 First the fans were placed in a test stand, where their free air RPM was observed. Then the fans’ noise was assessed. The standard proxy for what you can hear is the Sound Pressure Level (SPL), measured in decibels and given a type A weighting (dBA). A silent room is about 30 dBA.

Below you can find the best 60mm fans for computer cooling and for cooling down other devices. These 60mm fans can also be used as replacement fans for various devices. All the below-mentioned 60mm fans work on 12V only. Noctua NF-A6x25 FLX Fan and 40mm fans are also used for cooling down Server chassis (1U/2U), SFF or Mini-ITX PC, HTPC, Thunderbolt enclosure, eGPU box, Routers, Switches, Smaller CPU heatsinks, FLEX ATX Power Supply, Consoles (PS4 / Xbox, etc.), Inverters, Switches, 3D Printers, NAS server / RAID enclosure, DIY Projects, DVR / NVR systems, Raspberry Pi 3, Battery charger and other electronic devices. So, here I am going to list down the best 60mm and 40mm fans for use in various devices for providing excellent cooling performance. Moreover, these fans also serve as better replacement fans in devices and appliances that use 40mm / 60mm fans for cooling. Below 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 FanThe 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 The PWM fan we are examining came from Tao Bao in China. The model number is D1225C12B6ZPA44, with a nominal speed of 2150 RPM. The Gentle Typhoon is known for several things. One is the low amount of airflow compared to its high RPM. Another is that the fan is very quiet for the air it moves. It is also known for its high static pressure. We will see how this all turns out. Nidec Gentle Typhoon Noctua 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. 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.
