Noiseblocker BlackSilent Fan XS1-50mm

Product Information

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! Answers to comments: SPL I can measure and put numbers to. The "tone" of a fan is highly subjective. Ask Noctua and Nidec. Noctua’s industrialPPC line also uses a 3-phase motor. Most motors you see have four poles inside. These have six. 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. 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.

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. My, how time flies! Enermax released PWM fans with their three-position switches three years ago. We reviewed their fans then. I hauled two of those fans out of their case to compare them with other PWM fans. Although each of these fans has three speeds, we only test them with their switches in the H position, otherwise, I’d never get done. 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.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. 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.

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. 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. 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.

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. 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. 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

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 Fan 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 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.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.
