How much high temperature can the cooling fan resist?

Conventional cooling fans generally indicate that the temperature is between -10 and 70 degrees. Because the conventional cooling fans in this range are relatively reliable, someone will ask, can the material of the cooling fan only withstand high temperatures of 70 degrees ? u003cbru003e u003cbru003e u003cbru003e 　　 The temperature that materials can withstand is actually more than that, such as ICs generally can withstand 80 degrees, plastic parts generally can withstand 110 degrees, wires are 80 degrees, and motor copper wires can withstand 110 degrees. But we know that while the cooling fan is running, The motor itself heats up, the higher the current, the higher the temperature rise, so the ambient temperature of 70 degrees + its own temperature is definitely more than 70 degrees u003cbru003e u003cbru003e u003cbru003e 　　 Specially made heat-resistant cooling fan, can be designed at 85 degrees, using 100 degrees high temperature driver IC, 160 degrees motor copper wire, 180 degrees wire, plastic parts are made of fireproof materials, without reducing the speed Under the circumstance, the temperature rise of the motor itself is reduced, and the double ball bearing structure is used, most of which are designed in this way, and the work can be guaranteed in an 85 degree environment.
