If there is an imminent danger, in addition to any other action you take, you should telephone OSHA. Your Right to An Inspection Often, OSHA prefers to investigate complaints by faxing a letter asking about the hazard to the employer, rather than by conducting an on-site inspection.
(November 2014) A Totally Enclosed, Fan-Cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. An external fan blows outside air over the frame of the motor to cool it.
Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they generate.ans installed in a PC case can produce noise levels of up to 70 dB. Since fan noise increases with the fifth power of the fan rotation speed, reducing rotations per minute (RPM) by a small amount potentially means a large reduction in fan noise.
