Computer Cooling DigiTech

This fan evenly distributes the hot air rising upwards from your fireplace or stovetop to provide more effective heat circulation around the room. No batteries are needed! Simply sit the fan on a flat surface on top of the fireplace and it will automatically start to spin when the temperature exceeds around 60°C. The hotter it gets, the faster it circulates warm air throughout the room. - Silent and efficient - No batteries or electricity required - Colour : Black - Operating Temperature : 60.00000000°C, 345.00000000°C - Width : 160.00000000mm - Height : 210.00000000mm - Depth : 110.00000000mm - Weight : 650.00000000g
