The German company Blacknoise has been manufacturing case fans since 1998 and is known for its Black Silent fan and Ultra Silent fan series. However, with the introduction of the Noiseblocker eLoop fans in 2012, the company was able to inspire fans of silent PCs in particular. Because the NB-eLoop uses a bionically optimised design, they have managed to create some impressively low noise units. With the NB-eLoop X fan series, Noiseblocker now offers a special design fan for case modders, design lovers and RGB-LED fans alike.
The new X models come in either smart black or white, making them perfect for sprucing up the interior of your gaming PC while also improving overall airflow as well - without having to compromise on noise. The new, more neutral, colour scheme means they coordinate perfectly with just about any system, allowing users full freedom to select the combination of cases and fans that they want. Even the integrated RGB lighting is reserved: a total of seven digitally addressable RGB-LEDS are embedded in the hub and these help to illuminate the transparent fan blades as well as the frame.

Bionic Fans with Unique Blade Shape
The most striking feature of the bionic fans of Noiseblocker is the unique blade shape, which makes the noise of the airflow itself significantly quieter. At the same time, the fans help focus the airflow. This enables a more directional and efficient style of air flow, offering advantages depending on where they are being used and the components they are paired with (directional air transport, airflow management, water cooling etc).
Intensive Research with Governmental Funding
The eLoop fans are the result of research conducted by Dr. Rudolf Bannasch, who developed the basic principles of this style of rotor. The technology gradyated to production readiness in Noiseblocker's own developmental laboratory. This elaborate process was made possible thanks to funding from the German Federal Ministry of Economics and Technology. The aim of the project was to develop the "quietest fans in the world".
Energy- and Noise Efficiency
The technology that has been developed helps reduces the noise produced as a result of the air flow, with the total flow rate increased over a comparable area at the same RPM. The other consequence is this is a commensurate increase in energy savings during operation. In addition to the bionic (i.e. naturally occurring, simulated) fan shape and optimized electronics, the high-tech fans also feature other clever innovations. These include a newly revised NanoSLI bearing (version 2) from Noiseblocker with an encapsulated design for maximum protection against dust.
The NB-eLoop X B12-P ARGB works in a range between 0 and 2000 rpm thanks to PWM technology, generating a considerable static pressure of up to 3.020 mm H2O. However, it becomes absolutely impressive when looking at the airflow, i.e. the air flow rate. A remarkable 132.4 m³/h 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 28.4 dB(A) - this is a remarkable achievement in the world of air cooling.
Cable management, Decoupling and Lighting
Furthermore, 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.
A total of seven digitally addressable RGB-LEDs are installed in the hub, discreetly illuminating the transparent fan blades. Thanks to the widespread 3-pin connector (5VDG), the fans can easily be connected directly to an appropriately equipped motherboard or controller. The lighting can be controlled via ASUS Aura Sync, MSI Mystic Light or Gigabyte RGB Fusion.

High-quality, elegant as well as timeless design and technical innovation - these are the features of the Alphacool Apex Stealth metal fan. With its patent-pending decoupling technology, the robust metal frame and a special rotor, this fan certainly impresses. Not only is the Apex Stealth one of the most powerful fans, but it also remains the quietest at any speed.
• High performance and whisper quiet
• Patent pending decoupling technology
• Frame made of high quality metal
• Suitable for cases as well as radiators
• Controllable via PWM + Zero-RPM Control
Whisper Quiet
The fan blades, motor and its suspension are completely decoupled from the metal frame. For this purpose, a special damping system was placed between the metal frame and the fan, which absorbs all vibrations. This type of decoupling is a completely new system, which is brought to the market by Alphacool for the first time with the Apex fan. In addition, the impeller is equipped with a closed frame that prevents the impeller tips from fluttering at high speed, which also has a positive effect on the fan's characteristics.
Powerful All-rounder
The Alphacool Apex Stealth metal fan is a true all-rounder. It sets new standards in terms of airflow and static pressure. Therefore, this fan is not only perfect for mounting on radiators, but also provides excellent airflow as a case fan. The Apex Stealth can be controlled between 0 to 2000 rpm via the 4-pin PWM connector. The startup speed is ~420 rpm. In addition, the Stealth offers Zero RPM control, which can be used to bring the fan to a complete stop.
Apex Design
Alphacool's Apex product line represents the highest level of perfection. First-class materials and innovative technologies guarantee a unique premium product. Consisting of high-quality metal, the curved frame gives the Apex Stealth its distinctive design and fits perfectly into any PC build.
Additional Features
As usual with Alphacool, multiple fans can be effortlessly connected in series via daisy chain. The cables can be hidden in the corners of the fan so that they are no longer visible. A 50 cm PWM cable is also included as an extension. The 6-pole motor in combination with the HDB bearing (Hydro Dynamic Bearing) ensures extremely quiet operation and high durability.
