To ensure the normal operation of the ball bearing dc fan at high temperatures, the following measures can be taken:

Ensure that the device is well ventilated to allow the fan to effectively dissipate heat.

Periodically clean the fans to prevent dust and debris from blocking the fans and causing poor heat dissipation.

If possible, consider installing additional cooling devices, such as heat sinks or cooling fans, to improve the heat dissipation effect.

Follow the manufacturer's guidelines and recommendations to avoid use at temperatures beyond the heat-resistant range of the ball DC fan.
