Product Description
Be Quiet! Silent Loop 3 240mm ARGB Liquid CoolerUnleash Silent Cooling Precision
Innovative Cooling Block Design
The Silent Loop 3 240mm is a masterclass in thermal engineering, offering a dramatically enhanced 1,800 mm² fin area—double that of standard AIO coolers in its category. This large fin area, achieved through a screwless heat plate design, enables unparalleled heat dissipation across all CPU hotspots. With an optimized flow path architecture, it ensures even coolant distribution for maximum performance across AMD and Intel platforms. This engineering feat is tailor-made for PC enthusiasts who demand precision, silence, and exceptional thermal efficiency.
Whisper-Quiet Performance with Premium Pump and Fans
At the heart of this cooler is a sophisticated 3-chamber PWM pump, featuring a second chamber that acts as a turbulence-reducing reservoir. Combined with a 6-pole, 3-phase motor, it delivers stable coolant flow with minimal noise. Complementing the pump are two Silent Wings 4 120mm PWM high-speed fans with advanced blade geometry and a funnel-shaped air outlet, which enhance both airflow and acoustic efficiency. Whether you're rendering, gaming, or overclocking, this cooler delivers superb performance while maintaining an ultra-quiet environment.
Elegant ARGB & Refillable Longevity
Beyond performance, the Silent Loop 3 240mm is designed to impress visually and practically. The all-black cooling block features subtle ARGB lighting for a sleek, customizable look. It also includes a user-accessible refill port and bundled coolant bottle to ensure easy maintenance and long-term reliability. Combined with durable sleeved tubes and wide CPU socket compatibility, this cooler is a hassle-free, future-proof choice for builders who value both aesthetics and functionality.
