Nanoxia Deep Silence 140mm Ultra-Quiet PC Fan, 1100 RPM

This 140mm fan from Nanoxia is the same fan found in their excellent Deep Silence cases and therefore recommended if you plan to add more fans to the DS cases.

Features

Modern impeller design
Rifle bearing
7V adapter cable supplied
Optimised for Deep Silence cases
68.5 CFM, 14.4 dBA at 1100 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.

7-Volt Adaptor cable included

Unless a fan controller is available, the power and speed of the Deep Silence fans can be customised according to your individual requirements, using the included 7-volt adaptor cable.

Optimal upgrade for Deep Silence cases

Please note that the 120 mm and 140 mm models of the Deep Silence Nanoxia fan series are used in all Deep Silence cases. If you intend to add more fans to your Deep Silence case, it is highly recommended that you choose these fans since they perfectly harmonise with the included fans to provide optimum controllability of your system.

The 140 mm model of the Deep Silence fan series is supplied with a 7 volt adapter cable. At 12 volts the fan rotates at 1100 revolutions per minute. The Deep Silence 140 mm generates an air flow of 68.5 CFM at a noise level of 14.4 dB(A). Using the 7 volt cable reduces the speed to approx. 800 rpm, which generates and air flow of 52,4 CFM at 9.1 dB(A).

Customer Reviews

Amazing fans

Stojan Mihajlovski, 15th September 2016

I purchased one of these and a 120mm version for my Corsair Carbide 300r case and so far I’m very pleased. The only reason I’m knocking off a star is because the anti-vibration screws don’t fit on the front panel of the Carbide 300r, so I had to use regular screws there. Apart from that, the fans are great - they are efficient and very silent at the same time

Quiet and unobtrusive in my system.

Anonymous, 21st April 2013

I fitted two of these in my Fractal designs R3 case in the top rear and bottom positions pulling air in from below and exhausting at the top. My motherboard dropped about 2 degrees, measured with Speccy, as a result. I’m now quite happy that there is a decent volume of air wafting through my system. The fans are very quiet and have not added to the PC noise at all. In fact they are so quiet that the stock CPU cooler is now by far the noisiest component I have and it will soon be replaced. Happy with my purchase.

Great fan!

Very very quiet with nice airflow.

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.
