Cooling fan noise
the noise of the fan is the most high-profile projects macro morning electronic technology co. , LTD. , under the condition of meet the cooling premise, general requirements as small as possible noise, fan noise and friction, air flow, the higher the fan speed, air volume, the greater the is, the greater the noise caused by the vibration of the fan itself is also cannot be ignored, vibrations will, of course, the high quality fan itself is very small, then the front two are difficult to overcome, to solve this problem, we can try to use the size larger cooling fan. Big fan should be under the same air, work at low speed when the noise is smaller than small fan in the working noise at high speed, the other a factor: we are easy to overlook a cooling fan bearings, macro Chen has professional equipment to test the cooling fan noise, to provide professional services to our customers.
because of the Fan in the high-speed rotating between core shaft and the bearing friction, so is also a main source of Fan noise, Microphine to Fan noise testing standards. IM distance test, special to note will shorten the distance between the.
