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.

The 140 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 700 to a maximum of 1400 RPM. The Deep Silence 140 mm PWM generates an air flow of up to 76.5 CFM at a noise level of not more than 16.2 dB(A). A set of fan shock absorbers as well as a set of fan screws are supplied.

Customer Reviews

Cheap and effective fans


I bought 5 of these fans to replace all chassis fans within my PC. They run very quiet even under heavy loads. The PWM control is very useful to customise your fan speeds. The only thing which was annoying was during installation; the screws supplied seemed to be very tough to fix the first time. For the price these fans are very impressive.

Serves its purpose admirably


I bought 4 of these to use as top exhausts in a pair of Gelid Dark Force cases. I changed the CPU fan and the rear exhaust to the 120mm version; hitched them all up to a Gelid 1 to 4 PWM fan splitter so that they are all controlled by the motherboard PWM signal. At low to moderate loads my rig is virtually silent and it does not become very noisy even as the load and therefore fan speed increase. I would agree with another reviewer that this is not quite a silent as Noctua fans, but close enough - and these are less expensive! The supplied rubber mounts are easy to pull through the fans, but also easy to snap. I now have three spare mounts...

I've been used to buying fans from the Far East and these European made ones were a pleasant revelation.

great fans
