With integrated SMU, there is a smart algorithm to received temperature reading from multiple inputs, i.e., multiple GPUs power cores, external Bridge control logics, voltage regulator MOSFETs. This so called IFC (Intelligent Fan Control) not only limited to cooling GPU cores but also inputs from HBM, Power control logics (like MOSFETS). With more and more transistors and integration of High bandwidth memory (HBM), Sapphire introduces an even more intelligent scheme to monitor and dynamically adjust the fan speeds. At Sapphire, the experienced thermal experts always fine tuning the fan control table for each graphic card they designed. Traditional graphic cards cooling solutions mainly focus on keeping GPU at lower operation temperature while balance acoustic for end users to enjoy a quieter gaming experience.
