Noiseblocker BlackSilent Fan XS1-50mm

Product Information

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 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 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. 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. 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.

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 Testing The ambient noise for the current testing was 30 dBA. To measure noise levels that were softer than that, the sound pressure level was measured 10 cm from each fan. The sound pressure level was adjusted to 1 meter by subtracting 20 dB. The sound pressure meter was a Tenma 72-942. This fan tester has a microphone that is not accurate under 30 dBA. That means an adjusted measurement of 10 – 15 dBA is not accurate; the fan could easily be quieter than that. But this is the limit of all but the most expensive SPL meters. Test Stand There were two clear winners here, the Nidec Gentle Typhoon PWM and the Medium speed San Ace “Silent” PWM fans. It is too bad that these fans are among the hardest to get.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. FDB = Fluid Dynamic Bearing, a patented evolution of the sleeve bearing which causes the lubricating fluid to be recirculated within the bearing. 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. 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. 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.Sleeve bearing = the fan shaft is held in place by a diaphragm. The lubricant is held in place by a plug or the label. See here for a photo essay. 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. These fans come under their IT series of fans which are marketed for the PC users and the enthusiasts. We are reviewing the B12-PS and B12-P versions of the eLoop in 120mm category. 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. 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! All sorts of products from heatsinks to fans are made by Deepcool. Their GF120 fans have special airflow channels. We can only speculate what they might do for unrestricted airflow, but as you will see below these fans are surprisingly good at pushing air through a rad.

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. 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. 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 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. 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.

Versions

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 application comes with a clean and intuitive interface that is unlikely to give you any troubles. It is worth mentioning that the app scans your system for the audio drivers and, if it detects any issues, it prompts you to reinstall the utility or update the drivers to the latest version. As a side note, the tool does not provide the links for the newest drivers, so you need to look for that yourself. 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.
