OptiTech Features
Engineering Every Watt, Perfecting Every Detail
OptiSink™
OptiSink™ enhances heat dissipation by optimizing component layout and enabling direct thermal transfer through the PCB, improving cooling efficiency and reliability.
Advanced Thermal ArchitectureOptimized layout for efficient heat distribution
Reduced Circuit FootprintUp to 48% more internal space for better airflow
High Thermal ConductivityImproved 8x heat transfer directly through PCB
Enhanced Airflow EfficiencyBetter circulation for lower operating temperatures
OptiSilent
OptiSilent is Seasonic’s advanced fan control that balances cooling and noise through hybrid operation and real-time monitoring, ensuring quiet and efficient performance.
0dBA Hybrid ModeFan stays off at low load for completely silent operation
Digital Thermal ControlReal-time adjustment based on load and temperature
Smart PWM RegulationPrecise fan speed tuning for stable and efficient cooling
Optimized Noise-to-Performance RatioLow noise without compromising cooling performance
