About this deal

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.

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 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 Specs 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. 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. 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

Answers to comments: SPL I can measure and put numbers to. The "tone" of a fan is highly subjective. Ask Noctua and Nidec.

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 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:Originally the house label for Newegg, Rosewill does offer their products for sale in other places these days. They produce a bewildering variety of fans. Not so bewildering are the Hyperborea fans, in 12 cm and 14 cm sizes. These have relatively low speeds as if the makers were aiming at their being used for case fans, as well as on heatsinks and rads. The two units here were obtained retail. Rosewill Hyperborea 12cm San Ace

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! Noctua’s industrialPPC line also uses a 3-phase motor. Most motors you see have four poles inside. These have six. 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. 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 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.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 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. 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.

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. The PWM fan we are examining came from Tao Bao in China. The model number is D1225C12B6ZPA44, with a nominal speed of 2150 RPM. The Gentle Typhoon is known for several things. One is the low amount of airflow compared to its high RPM. Another is that the fan is very quiet for the air it moves. It is also known for its high static pressure. We will see how this all turns out. Nidec Gentle Typhoon Noctua 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.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. FDB = Fluid Dynamic Bearing, a patented evolution of the sleeve bearing which causes the lubricating fluid to be recirculated within the bearing. 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.
