WebJan 6, 2016 · If the resistor breaks or has any issues it may cause the fans to only function on certain settings. The cooling fan resistor is meant to send power to the fans in steps, so that the fans may operate at different speeds. If any of the individual steps or switches fail, it will disable the cooling fans from operating on that speed setting. WebMost resistors dissipate heat by convection into the air. If the power is near the maximum rated power for the resistor in question, the resistor will run very hot and its lifetime will …
