5.14. Temperature Range and Thermals

The recommended ambient operating temperature range is 0 to 50 degrees Celcius.

To reduce thermal output when idling or under light load, VisionFive 2 reduces the CPU clock speed and voltage. During heavier load, the speed and voltage (and hence thermal output) are increased. The internal governor will throttle back both the CPU speed and voltage to make sure the CPU temperature never exceeds 85 degrees C.

VisionFive 2 will operate perfectly well without any extra cooling and is designed for sprint performance - expecting a light use case on average and ramping up the CPU speed when needed (for example, when loading a webpage). If a user wishes to load the system continually or operate it at a high temperature at full performance, further cooling may be needed.
