Overheating
Heat sink temperature too high.
1. Ensure that the ambient temperature falls
within the specified temperature range.
2. Make sure that the ventilation holes are not
obstructed.
3. Remove any foreign objects from the
heatsinks and check for possible dirty heat
sink fins.
4. Check the fan and clean it.
5. Provide enough spacing for adequate
ventilation.
