Noiseblocker BlackSilent Fan XS1-50mm

Product Information

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 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: 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.

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

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. 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. 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

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.

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. The idea here is to have an overall design in such a way that straight path for the airflow can be ensured and to reduce the possible noise that comes from the airstream. The noise on the airstream is more than the body-borne noise of the traditional axial fans. This is due to the vortexes produced at the end or tip of the blades. To counter this factor, special rotor design is implemented in these fans in which the tips of the blades have no end as there is one continuous frame covering the ends of the blades. The Blade Master family of fans by Cooler Master have been around for some years. They have a wavy blade, and they’re pretty quiet. The two specimens in our testing were obtained at retail. Too bad they’re sleeve bearing fans. I won’t trust sleeve bearing fans on a heatsink.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 bionic loop fan is the world’s first such design to feature a bionic frame and bionic rotors. Combination of these two with the SLI2 and position invariant magnetic bearings have enabled the NB to deliver a product which delivers the same or better performance level as can be had from the axial fans but at much less noise level. The fans are modular as well. Unlike standard axial fans with fixed power connector, these fans don’t have fixed connectors.

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. 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. 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.

The B12-PS fans are rated at 12V DC with an input power of 0.95W using the 0.082Amperes. The starting voltage for these fans is 6.2V. The fans are rated at 400 to 1500 RPM at 12V. 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.
