DJI has given its small Mini 3 Pro drone numerous improvements over the previous model, such as an extended battery life, a higher-quality camera, as well as an improved obstacle avoidance function and video transmission system. testimonials from users, however, now also talk about a more common problem, namely overheating of the Mini 3 Pro.
When does the DJI Mini 3 Pro overheat?
The reason for this is a deliberate design decision by DJI: it has dispensed with the internal fan that was still present in the previous model, this was replaced by a lighter passive heat sink. While this has the advantage of not only saving some weight that could be used to meet the magic 249 gram weight limit for other components, it also consumed less power, thus extending flight time on the new model.

DJI relied on having enough cooling in all important situations, i.e. during flight recording, by means of the air currents generated by the propellers on the heat sink. Therefore, the lack of a fan causes problems when the drone is in operation and generates heat, but is not flying, but standing on the ground, such as when transferring the flight recordings by cable to a PC or when updating the firmware. Then it can happen that the Mini 3 Pro switches itself off due to the lack of airflow because of overheating - DJI has equipped it with its own temperature control system especially because of the lack of a fan to prevent damage from overheating components.

However, the amount of time it takes to shut down depends on the outside temperature and the operating mode. At 25° Celsius, DJI says it should be possible for about 22 minutes of operation in standby mode or 19 minutes of firmware updates and about 35 minutes of QuckTransfer before the drone overheats. So for many users, if they stay within that time frame or even operate at lower temperatures, they won&t hit the Mini 3 Pro&s heat limit. For the vast majority of Mini 3 Pro pilots, the increased functionality will likely far outweigh the problems caused by overheating (which, after all, only occurs in certain circumstances). Here&s our review of the DJI Mini 3 Pro.
How can you avoid overheating?
However, if you often experience overheating of your Mini 3 Pro - for example, because the outside temperature is already high - and your work is often disturbed by it, you can try to cool your drone with a table fan or (in case of heat problems during data transfer) transfer the video data to a PC using an SD card and a card reader instead of using cables with the drone turned on.
