The NF-F12’s, the NF-F12 industrialPPC’s, and the NF-P12 were provided by Noctua. Noctua NF-P12 Rosewill 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. Kolink International Corporation is a Taiwanese cooling specialist, one of their brands is called Coolink. Kolink says this about Coolink: “Kolink’s retail brand Coolink stands for an effective conjunction of no-frills performance, excellent quality and attractive pricing.” As of this writing it is unclear that Coolink still exists, but the fans are still for sale at various places.

FDB = Fluid Dynamic Bearing, a patented evolution of the sleeve bearing which causes the lubricating fluid to be recirculated within the bearing.

Welcome to the future!

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.

The first picture shows you an NF-F12. This fan has relatively high static pressure compared to its nominal output. It should. It was invented to be a radiator fan. But then it entered a new life. It became an industrial fan, the NF-F12 industrialPPC. Noctua tells us: Case fans generally come in two core sizes including 120mm and 140mm versions. Apart from the fan diameter and location of the holes to attach to the chassis both are pretty much the same. Occasionally cases have a front or top 200mm - 230mm fan but with manufacturers producing more slim and sleek case designs, the larger fans are getting integratedless. Water Cooling Radiator Fans 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.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. 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 All the outputs all turned out to be underestimates, to one degree or another. The SPL varied. In some instances the fan made fewer dBA than specified. 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.

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. Buy GDSTIME 40x10mm 5V Brushless DC Fan USB 40mm Fans 5V AC Infinity MULTIFAN Mini 40mm Quiet USB Cooling Fan Noctua’s industrialPPC line also uses a 3-phase motor. Most motors you see have four poles inside. These have six.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. 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 static pressure is rated at 1.475 mmH₂O at 12V. The air flow is rated at less than 58.1 CFM equivalent to 98.7 m³/h. The sound pressure is rated at less than 21.2 dB(A) at 100CM. The loudness level is 0.440 Sone (N) at 100CM. The MTBF is 140000 Std./hours. Operating temperature for the fans is -10°C to +60°C. 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.
