Nanoxia Special N.N.V. Fan 120mm PWM

The Special N.N.V. Fan 120 PWM is the ideal candidate when looking for a quiet and effective PWM fan for a CPU cooler, chassis or even a radiator.

Features

  1. World’s first vibration-free PC
  2. 4-pin PWM Fan
  3. FDB bearings
  4. 52.6 CFM, 24.6 dBA at 1650 RPM

Nanoxia’s Special N.N.V fans feature a patented technology that makes it the world’s first vibration-free PC fan by decoupling the two fan frames. The outer frame (grey) provides mounting points for the fan whether it be on the chassis or a CPU cooler. The inner fan frame (green) is decoupled with four plastic dampers (from the grey fan frame) and which contains the rotor and the fan motor. This means the vibrational noise emitted by the Special N.N.V. is virtually none existent!

The motor of the fan receives its PWM signal via a 4-pin connection on the motherboard. The fan electronics evaluate the signal and temperature of the hardware and then regulates the speed of the fan automatically. The PWM control of the Special N.N.V. Fans features a very linear control range, so that speed changes are hardly noticable.

The fan features FDB bearings which are very robust and long-lasting and the rotor and fan blades are optimally balanced. Which when added together guarantee a particularly long life span.

The Nanoxia Special N.N.V. 120 PWM fan rotates at 400 - 1650 RPM and therefore offers a very wide control range, providing a maximum airflow of up to 52.6 CFM and noise levels that do not exceed 24.6 dB(A).

FAQ

  • How do I measure fan size?

    The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases.

    As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. All our fans are 25mm thick unless otherwise stated. If you have any questions about which fan you should order, please don’t hesitate to get in touch.

    If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.

    83mm between screw holes:92mm fan size
    105mm between screw holes:120mm fan size


  • I received a small cable (resistor) with my fan; what is it for?

    The resistor cable (also called Ultra Low Noise or ULN cable) is designed to allow the fan to run slightly slower for even quieter operation. The benefit in lower running noise is significant. Although the airflow will be reduced slightly, this usually has minimal effect on PC temperature. We would generally recommend using the ULN resistor cable for best results in almost all circumstances.

  • How can I tell which way the air blows through the fan?

    Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case. Some fans also have two small arrows moulded into their plastic housing - one arrow shows the direction of airflow, and the other (at 90°) shows the direction of blade rotation.

  • Is it possible to use a 4-pin PWM fan or CPU cooler with a motherboard which has only 3-pin fan headers on it?

    Electrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.

    The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.

    Another avenue to explore is the possibility of using a bay-mounted fan controller. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.

“Great service.”

“Great service. One thing to note :: the power supply comes with a European 2 pin power lead. Not listed in the description. Not a problem for me as I had the old one.”
