We thoroughly scrutinize and optimize every single cooling component used in our INFINITUM PCs, ensuring maximum durability at minimum noise.
CONFIGURATION
INFINITUM Pro 4U is a fully air cooled system available with a premium extra-large, dual 120mm, heatpipe CPU cooler. A 120mm exhaust fan and 140/120mm intake fans create positive pressure inside the case and efficiently cool all core components.
SPECIALIZED FANS
Engineered and selected for thermal performance
- Pressure- or airflow-optimized fans w/ ultra-quiet, premium-quality bearings

- Customized fan curves – every system is hand tuned to be as quiet as possible
PEACE AND QUIET
Building quiet computers is our obsession. All our cooling components are carefully selected for their durability, efficiency and noise levels. Each fan is hand-tuned with a variable RPM curve to ensure maximum quietness at all load levels. We guarantee that every STEIGER DYNAMICS system is virtually inaudible during regular usage. We achieve this by employing highly efficient air or liquid cooling, anti-vibration materials, acoustic insulation, and custom BIOS/firmware settings to ensure minimal audibility at maximum performance.
