Most owners don't understand that electronic devices like Game Consoles, Gaming Laptops and Gaming or Custom Built Desktops require servicing at certain periods this even includes any device that cycles air with a cooling fan and in most cases uses a thermal paste on its CPU, GPU or APU.
Servicing points vary depending on the device and its on-duty and a good example of this would be a PS4 with a High Fan that is dropping out (Thermal Shutdown). Consumers (Owners) must see this as a running cost of keeping the device at the correct temperature and in the best condition.
