The cooling fan noise test
a cooling fan noise is generated when the fan noise, the size of the affected by many factors, the unit is decibels ( dB) Test is required when the fan noise in the noise is less than 17 db quieter room fan 1 meter distance, and along the direction of the fan rotor on the fan air inlet, with the method of weighted measurement, the fan noise spectrum is also very important, so need to use frequency discussion record fan noise frequency distribution, generally requires as far as possible little fan noise, and there can be different.
