Product Overview

Impulse 120 D-RGB Fan

EK-Quantum Impulse 120 D-RGB is a silence-oriented 120mm computer cooling fan designed and built primarily with the lushest RGB LED illumination in mind. They are not a replacement for other EK fans that maintain a focus on high radiator performance but more of an aesthetic-focused offering that provides silent operation and balanced performance.

MagLev Fans

EK-Quantum Impulse fans have the VAPO™ bearing and Magnetic Levitation motor.

Addressable RGB LED MagLev Fans

EK-Quantum Impulse are 120mm PC radiator and case fans optimised for rich and lush D-RGB effects while maintaining very silent operation across their entire operational range. There is one LED-lit zone around the frame on both sides of the fan, so no matter which fan orientation you require, you'll get the rich illumination of the addressable RGB diffused through a milky white cover. The rotor is also illuminated by its own D-RGB strip for stylish aesthetics while spinning.
These fans use VAPO bearing, designed to virtually eliminate wobbling, so it stays incredibly stable in all applications. VAPO bearing adds a magnetic effect (magnetic levitation) to the bearing to reduce noise and increase shaft stability. Unlike the traditional ball-bearing fans that get noisier with time, VAPO bearings are dust-resistant and don't dry out.
As with FPT fans, Impulse fans also allow daisy-chaining, ultimately reducing cable clutter and easing cable routing through the EK-OmniLink, an 8-pin Micro-Fit connector ecosystem. All the signal and power wiring for the PWM and D-RGB runs on a single cable and connector, which then utilises another single cable to connect to the source. Most importantly, the EK-OmniLink ecosystem doesn't require any special controllers since the connection ends in the standard motherboard connectors - a 4-pin PWM for the fan power and a 3-pin 5V D-RGB for the connectors.

Rubber Dampers on the Corners

Thick rubber corners can be found on both sides of the fan to reduce vibration transfer to the rest of the PC. The fan itself is 26mm thick, with rubber corners protruding 1.5mm on each side for a total of 29mm in depth, bearing in mind that these rubber corners will squish down as you tighten the screws.


EK-OmniLink – allows daisy chaining of multiple fans, thus reducing cable clutter and greatly easing cable management. The Omni-Link ecosystem of interconnects will be greatly expanded in the near future, allowing additional benefits to users. It uses Micro-Fit 8-pin connectors between products, but standard 4-pin for PWM and 3-pin for 5V addressable RGB at the end of the daisy chain.
The EK-OmniLink design resolves the cable clutter issues of unifying the connection of multiple fans onto a single PWM and D-RGB header while still maintaining full flexibility if the user wants to remove a single fan from the chain. Other similar solutions on the market use interlocking mechanisms, which require the removal of the entire fan link if the user needs more room to tighten a fitting on a radiator.

3-Zone LED Illumination on EK-Quantum Impulse 120 PC Fan

One of the main features the new EK-Quantum Impulse 120 fan offers is its simplicity. It utilises the standard 3-pin 5V D-RGB connection, meaning you can use it with any standard 3-pin 5V addressable RGB controller or any of the popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector should be aligned with the +5V marking on the D-RGB (ARGB) header.


Three Premium LED-Lit Zones: Unlike other EK fans, which have LEDs exclusively in the rotor, Impulse fans have additional LEDs on both sides of the frame.
MagLev and VAPO Bearing: The VAPO bearing adds a magnetic effect (magnetic levitation) to the bearing to reduce noise and increase shaft stability.
Square Frame for Airflow Focusing: The practical square shape of the fan frame provides optimal performance in either the pull or push regime without hydraulic losses, which ensures the optimal cooling capacity of your liquid cooling radiators.
Standard D-RGB Connectors: The EK-Quantum Impulse 120 fan's D-RGB lighting does not require any fancy or expensive additional controller for you to enjoy vibrant light effects. A simple 3-pin 5V addressable D-RGB connection for standard controllers or any popular D-RGB (ARGB) sync technology from major motherboard manufacturers is all you need.
OmniLink: The ability to daisy chain fan power, D-RGB, and even pump power across a single cable gives you the ultimate flexibility while reducing cable clutter. All the cables are flat ribbon style with no additional sleeving for an even better cable routing experience.

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.

Anybody who has been near their share of computer systems will appreciate that not all systems make the same amount of noise. There are a number of reasons for why this is so. Firstly, a computer makes noise for different reasons. Generally, anything mechanical is going to make noise.
