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

  • Compatible with LGA 1700

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).
