Nanoxia Deep Silence 120mm PWM Ultra-Quiet PC Fan, 650-1500 RPM

Developed for very low noise operation, the Nanoxia Deep Silence PWM fan series provide peace of mind that if temperatures raise so will the cooling.

Features

Modern impeller design
4-pin PWM Fan
Rifle bearing
63.7 CFM, 16.9 dBA at 1500 RPM

Deep Silence fan series

The Nanoxia Deep Silence fan series have been optimised for very low noise operation. The fan frame and the impeller were developed in the wind tunnel allowing them to be optimised in many tests.

Modern impeller design

The impeller design of the Deep Silence Nanoxia fan has been perfected over many years of development. It allows the best possible compromise of efficient air flow rate and the lowest possible noise level.

Rifle Bearing

The Rifle bearing of the Deep Silence fans meets the latest standards and is of the highest quality. The high-quality bearing results in a particularly high life expectancy of at least 80,000 hours, and a very quiet cooling fan operation - especially at low speeds - is guaranteed.

PWM Series

This fan features PWM functionality, meaning the fan’s PRM is controlled by motherboard. The speed of the fan will increase or decrease depending on the temperature of the installed components along with the motherboard’s BIOS settings. This gives peace of mind that if temperatures raise so will the cooling provided by the fan.

This 120 mm model of the Deep Silence fan series is equipped with a 4-pin PWM connector for automatic adjustment of the fan speed. The rotary speed spectrum ranges from 650 to a maximum of 1500 RPM. The Deep Silence 120 mm PWM generates an air flow of up to 67.3 CFM at a noise level of not more than 16.9 dB(A). A set of fan shock absorbers as well as a set of fan screws are supplied.

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.

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.
