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.


  1. Modern impeller design
  2. Rifle bearing
  3. 7V adapter cable supplied
  4. Optimised for Deep Silence cases
  5. 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


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.


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.
