Intelligent Temperature Control: Combined with a temperature sensor, it can automatically adjust the fan speed according to the internal temperature of the projector, ensuring proper heat dissipation while avoiding unnecessary energy consumption and noise. Safety Overload Protection: Built-in overload protection device. When the fan encounters abnormal situations such as jamming or lock-up, it will automatically cut off the power to protect the motor, enhancing operational safety. Maintaining Internal Constant Temperature: By continuously circulating air, it balances the temperature of different areas inside the projector, preventing performance fluctuations caused by localized overheating, ensuring stable output of parameters such as image quality and brightness. 1pc Cooler Replacement Projector Cooling Fan CE-7039L-301 ,Compatible For Epson ,CH-TW5210/ TW5300/ TW5350
