Ventoinha EK Water Blocks 12 cm branca 400-1800 rpm

EK-Quantum Impulse 120 D-RGB is a 120 mm white computer cooling fan designed for quiet operation and rich addressable RGB illumination. The fan combines a square frame with rubber corner dampers, a VAPO bearing with Magnetic Levitation motor and three-zone D-RGB lighting (frame on both sides and hub) to deliver balanced cooling performance, low vibration and visually consistent illumination. It connects via the EK-OmniLink system that allows daisy-chaining of power, PWM and 5V D-RGB signals using Micro-Fit 8-pin interconnects and standard 4-pin PWM / 3-pin 5V D-RGB motherboard headers.

Advantages

The Impulse 120 offers silent operation across a 400–1800 RPM range while providing rich, diffused D-RGB effects through milky white covers on the frame and additional LEDs on the rotor hub. VAPO bearing with magnetic levitation improves shaft stability, reduces noise and increases dust resistance compared with conventional bearings. Thick white rubber dampers on all corners reduce vibration transfer to the chassis, and the square frame reduces side air leakage for consistent radiator performance. EK-OmniLink simplifies cabling by allowing multiple fans to share a single PWM and D-RGB connection without requiring proprietary controllers.

Suitable for

• PC radiator cooling in liquid-cooled systems
• Case ventilation where quiet operation and lighting are required
• Builds that need daisy-chained fan and D-RGB connections to reduce cable clutter

Key specifications

• Fan size: 120 mm (120 × 120 × 29 mm including rubber corners)
• Speed range: 400–1800 RPM
• Minimum air pressure: 1.94 mmH2O (manufacturer data)
• Colour: White
• Bearing/motor: VAPO bearing with Magnetic Levitation (MagLev)
• Lighting: 3-zone addressable 5V D-RGB (frame both sides + hub LEDs)
• Connectors: EK-OmniLink daisy-chain (Micro-Fit 8-pin) with standard 4-pin PWM and 3-pin 5V D-RGB at chain end

How to use

Install the fan in your case or on a radiator using the standard screw holes; account for the 29 mm total depth including rubber dampers, which compress slightly when tightened. Connect the daisy-chain cable bundle between multiple Impulse fans using the Micro-Fit connectors, and attach the final cable to the motherboard 4-pin PWM header for fan speed control and the 3-pin 5V D-RGB header for addressable lighting. Follow the arrow marking on the 3-pin connector to align with the +5V pin on the motherboard D-RGB header.

Recommendations

Use the EK-Quantum Impulse 120 D-RGB with standard 3-pin 5V addressable RGB controllers or motherboard D-RGB headers for lighting; avoid forcing connectors or bending flat ribbon cables sharply. For optimal vibration reduction, ensure screws are tightened evenly so rubber dampers compress uniformly, and do not replace the rubber corners with non-damping spacers.
