Be Quiet! Silent Loop 2 240mm ARGB Liquid CPU Cooler


Silent Loop 2 240mm is the very high-performance and whisper-quiet all-in-one water cooling unit for demanding systems.

  • Dampened and adjustable pump with six-pole motor for very silent and very high-performance operation
  • Powerful three-chamber pump design significantly reduces turbulences and noise
  • Silent Wings 3 PWM high-speed fan for high performance and whisper-quiet operation
  • Cold plate with high density stack of fins for the highest cooling characteristics
  • ARGB LEDs for lots of illumination options and great visual effects
  • Easy-to-access refill port with coolant bottle included, ensuring a long lifespan
  • Three-year manufacturer’s warranty
Superior Pump Design   Whisper-quiet operation   Powerful pump with innovative three-chamber design ensures the very high-performance Silent Loop 2 240mm is whisper-quiet at the same time. The second of its three chambers offers enough space for the coolant to spread out and thus reduces turbulences before it leaves the pump unit. In combination with the 6-pole three-phase motor this results in a smooth and as a consequence silent operation.
Whisper-Quiet Operation   Thanks to effective pump dampening   The massive dampening of the pump absorbs vibrations and as a consequence minimizes the resonances in the pump housing. This leads to significantly reduced noise and is key to the famously whisper-quiet be quiet! operation. Very High Cooling Performance   For low CPU temperatures   Silent Loop 2 240mm as an all-in-one water cooling unit provides enough cooling performance even for demanding applications when the CPU is pushed to its limit. The pump, radiator and fans are all optimized to work in perfect technical symbiosis.
Big Coldplate   For all consumer platforms   Having a high density stack of fins on one side and a nickel coated plate on the other, the cold plate provides maximum cooling performance for the AiO. This makes Silent Loop 2 240mm the perfect water-cooling unit, especially for high-end processors and those with large surfaces. sTRX4 mounting is available separately.   Silent Wings 3 Fan   Impressive ratio of performance to noise   The Silent Wings 3 240mm PWM high-speed fan features seven airflow-optimized fan blades, a 6-pole motor for less vibration and a durable fluid-dynamic bearing. The fan frame is equipped with funnel-shaped air inlets for extremely high air pressure, which makes the fan the perfect choice for radiators.   Impressive Illumination   Lots of options and great visual effects   ARGB LEDs offer multiple colors and modes to individualize the look of the Silent Loop 2 240mm. The illumination can be synced with the ARGB adjustments of the motherboard. You can optionally use the wired ARGB remote controller to switch between modes and colors. The white illumination of be quiet! sign can be turned on and off for an external appearance of any taste.   Easy to Refill   Simplified refilling process for a long lifespan An easy-to-access refill port makes for convenient handling, safe refilling and comfortable maintenance. The coolant bottle included ensures a long lifespan.
