Hydro Series H75 provides effective and efficient liquid CPU cooling in a compact size. The 120mm radiator has a thickness of only 25mm and is paired with standard diameter, kink-resistant tubing for compatibility with smaller cases and tighter spaces. Dual high-torque SP120L PWM fans are quieter and more efficient at dispersing heat than single fan designs – and can plug directly into a PWM fan header on the motherboard for automatic fan speed control based on CPU temperature. The tool-free mounting system has broad Intel and AMD socket compatibility. A copper microfin coldplate and high-quality ceramic bearing pump provide reliable, low-noise CPU heat rejection.
