Noiseblocker BlackSilent Fan XS1-50mm

Product Information

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. 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. 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. 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.

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. 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 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

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. 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. The fan comes with a multi-speed controller attached to it for changing fan speed to low, medium, and high. You can also use it to turn the fan completely off when required. The fan blades are protected by the metal grill on both sides. Even being such a high-performance and high RPM fan, the fan is very silent and has a maximum noise rating of 18 dBA only. So, if you are looking for a multi-purpose 40mm fan with high performance and manual speed control, then look no further and get this one today. AC Infinity MULTIFAN Mini 40mm USB Cooling Fan SpecsConceived 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. 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 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. 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 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 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.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 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. Another 5V 40mm USB fan but this one is cheaper and comes with almost the same features as found in AC Infinity MULTIFAN Mini 40mm Quiet USB Cooling Fan. The fan comes with ball bearing, a metal grill for protection, and a 3 Speed fan controller. The fan has a maximum speed of 5300 RPM but airflow is a bit lower at 4.4 CFM, considering the fan speed. However, it is still adequate and can be used for ventilation of VR glasses, TV boxes, Raspberry Pie, Router, Small PC Case, PlayStation, Xbox, DVR / NVR, DIY Projects, and other small electronic equipment ventilation. The fan is on the noisier side and has a maximum noise rating of 27 dBA. The USB cable is 3.3 feet long which I think is pretty decent for normal use. So, if you want a cheaper alternative then you may go for this one. The NF-F12’s, the NF-F12 industrialPPC’s, and the NF-P12 were provided by Noctua. Noctua NF-P12 Rosewill 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.
