The explanation may look complicated, but we owe it to our most loyal fans and all the enthusiasts out there: The cooling block boasts a 1,800 mm² fin area, which is an increase of up to 2x compared to many other AiO's in this class. This greatly improves heat transfer and makes sure to cover all hot spots on the CPU. The large fin area could only be achieved by a specially developed screwless design for attaching the heat plate. The internal design of the flow path takes care that all areas are flowed to evenly to achieve high performance regardless of the CPU platform.\u003c\/p\u003e\u003cp\u003eA powerful PWM pump with 3-chamber design ensures the very high-performance of Silent Loop 3 420mm and is whisper-quiet at the same time. The second of its 3 chambers acts as a reservoir and offers enough space for the coolant to spread out and thus reduces turbulences before the liquid leaves the pump unit. In combination with the 6-pole 3-phase motor this results in a smooth and consequently silent operation.\u003c\/p\u003e\u003cp\u003eSilent Loop 3 420mm features 3 Silent Wings 4 140mm PWM high-speed fans. These fans feature silence-optimized fan blades and a funnel shaped air outlet, making Silent Wings 4 140mm PWM high-speed a fan that makes no compromises between very quiet operation and highest performance. The corners of the frame are designed to minimize air leakage on radiators.\u003c\/p\u003e\u003cp\u003eSilent Loop 3 420mm is a meticulously crafted masterpiece of German engineering. All parts integrated are of highest quality and work as precise as a clockwork, ultimately leading to a cooling performance ready for virtually any situation.\u003c\/p\u003e\u003cp\u003eThe cooling block's design is iconic and unmistakable. We kept it all-black and elegant to represent the sheer cooling power Silent Loop 3 420mm offers, despite being barely audible. Optionally, you can turn on ARGB LEDs. Silent Loop 3 420mm is a statement in your PC case: you strive for the maximum in any discipline.\u003c\/p\u003e\u003ch5\u003eSpecifications\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003eGeneral\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;margin-bottom:10px;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003ebe quiet!\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003eBW026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003eAll-in-One\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;margin-bottom:10px;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eRadiator Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e420mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eRadiator Dimensions\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e457 × 140 × 27 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eCooling Block Dimensions\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e93.5 × 80 × 56 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eCooling Block Fin Area\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e1,800 mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eTube Length\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e410 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eFan\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;margin-bottom:10px;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan System\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e3 × Silent Wings 4 140mm PWM High-Speed Fans\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan Dimensions\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e140 × 140 × 25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan Speed Range\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003eUp to 1,900 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan Airflow\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e78.4 CFM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan Static Pressure\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e2.36 mm-H₂O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan Bearing Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003eFluid Dynamic Bearings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan MTTF\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e300,000 Hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;font-weight:bold;width:35%;\"\u003eFan Power Connector\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border:1px solid #ddd;\"\u003e4-pin PWM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eAcoustics \u0026amp;
