Less heat, more productivity2
To ensure stable performance in the compact chassis, ASUS S503MER employs an innovative multi-channel cooling system. This comprises dedicated, isolated air chambers that allow independent heat-venting channels for the PC’s main thermal generators — the CPU, GPU and power supply. ASUS S503MER also includes the exclusive MyASUS app to optimize the operation of the CPU and system fans, automatically moderating the speeds and switching them off completely when possible, striking the perfect balance between maximum performance and minimum noise.
