To cool the motor, MSI has multiplied the air vents. These are big and well placed. The air vents in front cool the disks and memory and those in the back ventilate the processor, the video card and the power input.
To cool the processor and help air circulate inside, MSI has fitted the radiator with two fans. The radiator just has blades, not a heat pipe in sight.
When it is running, the system never overheats. Hot air is expelled by the power supply. The proportions are the same as on other mini-PCs. Noise is low, as on the previous model.
