How Radiator Fans Work. Radiator fans work by increasing airflow around the radiator. The radiator is the heart of your vehicle's cooling system. It contains thin and hollow pathways through which liquid coolant can flow. As coolant travels to your vehicle's engine, it will absorb heat. The hot coolant will then return to the radiator where it Radiator (heating) Heat exchange by built-in bathroom radiator uses hot water flow through the stainless steel pipes seen here to raise the temperature of the ambient air. The radiator depicted here also serves as a towel rack and warmer. Radiators and convectors are heat exchangers designed to transfer thermal energy from one medium to another
PRO: Lower voltage. DC fans generally use less voltage than AC fans. The majority of DC fans are low-voltage fans. For example, you can typically find 5V, 12V, and 24V versions of DC fans. Larger models of DC fans, such as 119mm to 172mm fan models, are typically available in 48V. In comparison, most AC cooling fan models are available in 115V

Our thermostats should be fully opened by 195 F/90 C, and cooling fan should be coming on by 210 F as far as I know. I'd consider changing thermostat if you're over 80K, and definitely suspect that cooling fan cause something isn't right. . 340 379 93 264 4 62 213 285 236
