OptiTech Features

Engineering Every Watt, Perfecting Every Detail

OptiSink™

OptiSink™ enhances heat dissipation by optimizing the internal component layout and enabling more effective direct thermal transfer through the PCB. This design helps distribute and remove heat more efficiently from critical components, supporting lower operating temperatures, improved cooling performance, and greater long-term reliability, particularly during sustained or demanding workloads.
