Cooling fan common faults and its solutions


the cooling fan is common faults are:


1, when the cooling fan rotation during use, sometimes heard a bump in the 'man', sometimes not. Turned out to be a cooling fan are gathering in the messy wires and power cords, sometimes thrum met fan blades and led to a cooling fan rotates, the abnormal sound.


the solution: use half a fan like rubber bands, tape paper inside the cable, power cord strapped up, avoid the pass through the top of the cooling fan.


2, there is a cooling fan fault phenomena, at the early stage of the cooling fan using normal, but suddenly found nearly a period of time the fan automatically move a fixed position, after the check, the original fixed radiator button failure, due to the resonance phenomenon caused by the fan operation, lead to displacement of the fan.


the solution: to replace the new buckle.


3, a cooling fan when use the characteristics of noisy noise suddenly, even larger than the noise of the chassis power, this is because the surface of the cooling fan and radiator gap gathered too much dust. Fan motor lubricating oil has completely dried up, so the roar of the motor.


the solution: we can make a cooling fan and radiator, radiator directly with tap water wash. With soft paper to wipe a cooling fan, first crack of the available medical sign a wipe. Turn on a fan of plastic stickers, using ordinary sewing machine oil into the machine core a drop or two drops.


4, some cooling fan with less than a week if there is too much noise, and turns not free until the phenomenon. Just boot fruit is slow, the speed of the fan and the noise is bigger, a period of time and then returned to normal, the reasons for this kind of case is generally because the cooling fan of the indoor temperature is low, cause the rotation bearing lubricating failure.


the solution: to a cooling fan injection antifreeze lubricating oil, and pay attention to using the environment temperature, and pay attention to maintain it.


the cooling fan is common faults and its solution is introduced to this, caused by the above content we can know that there are many reasons for the cooling fan is in failure, so when in use at ordinary times have to be the maintenance for it, so as to prolong its service life.
