The Celsius series is all about delivering the best possible cooling with the least possible noise Smart temperature-controlled mode adjusts fan/pump speeds in real-time PWM mode enables precision manual tuning for any situation Included PWM fans with wide speed adjustment range (500-2000 RPM) No additional software needed Both fan and pump speeds can be managed by an intelligent auto mode or switched to PWM mode for precise user control. For true enthusiasts, the satisfaction of a clean and efficient build can never be overstated, and the Celsius makes this easier than ever with an integrated fan hub and concealed cable routing. Key features Included Fractal Design Dynamic X2 PWM fans offer a wide speed adjustment range from 500 to 2000 RPM allowing for near silent operation under lighter loads and maximum airflow during heavy usage Radiator fittings use standard G 1/4\" thread for maximum compatibility and expandability with standard do-it-yourself components Easily add and integrate a GPU block of your choice to eliminate noisy graphics card fans so the only sound you hear is the sound of your game Dynamic X2 PWM fans Included Fractal Design Dynamic X2 PWM fans Premium sound dampening materials An intelligent temperature-controlled auto mode adjusts fan and pump speeds in real-time for optimum balance of cooling performance and silence, while PWM mode enables precision manual tuning for any usage situation.   Standard G 1/4 thread fittings Radiator fittings use standard G 1/4\" thread for maximum compatibility and expandability with standard DIY components Specification Type: Liquid CPU Cooler AMD/Intel: Combo Compatibility: \"Intel: 1200, 1150, 115X, 1366, 2011, 2011-v3, 2066 (via included 2011-v3 kit) AMD: AM2, AM2 , AM3, AM3 , AM4, FM1, FM2, FM2 , TR4 (via included bracket in AMD Threadripper box)\" Installation: Port threads: G 1/4\"\" Fan screw threads: UNC 6-32 LED Lightin No Colour: Black Material: Housing material: Aluminium Fin material: Aluminium Fan Dimensions: 120 mm Dimensions: 403 x 123 x 30 mm Fan Controller: PWM Rotation Speed: Fan: 500 - 2000 RPM Pump: 1950 - 3150 RPM Fan Bearin LLS Air Flow: 87.6 CFM Noise level: \"Fan: 32.2 dB (A) Pump: 20,0 dB (A)\" Power: Input voltage: 12 V Input current (without fans): 0.15 A Rated input power (with fans): 9 W Additional Features: See Overview / Video MTBF: \">50,000 hours\" Package Contents: Celsius S36 system 3x Dynamic X2 GP-12 PWM fans Multilingual user manual Mounting hardware for all listed sockets Fan and radiator mounting screws Package Type: Retail Package Weight: 2.2680 kg Warranty: 5 Years
