The Celsius series is all about delivering the best possible cooling with the least possible noise Extreme cooling performance and minimal noise output Intelligent temperature-controlled mode adjusts fan and pump speeds in real-time Included PWM fans with wide speed adjustment range(500-2000 RPM) Key features The Celsius series lets you choose between an intelligent temperature-controlled auto mode to adjust fan and pump speeds in real-time for optimum balance of cooling performance and silence, or a PWM mode enabling precision manual tuning for any usage situation imaginable. Radiator fittings use standard G 1/4\" thread for maximum compatibility and expandability with standard DIY 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 Temperature-controlled An intelligent temperature-controlled auto mode adjusts fan and pump speeds in real-time for optimum balance of cooling performance and silenc Fan hub An integrated fan hub with concealed cable routing simplifies cable management for a clean installation Thermal grease Thermal paste is pre-applied and has high thermal conductivity Long-lasting fans 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   5-year warranty pre-expansion (Post-expansion, only individual components of the Fractal Design Celsius S24 or S36 are covered).
