Believe applied dc cooling fan manufacturers understand, dc cooling fan is a dc voltage and electromagnetic induction, and by the electrical energy into mechanical cooling device to drive the blades rotating, it has quick speed, thermal properties and is widely used with good effect, however, dc cooling fans sometimes branch which appear all sorts of problems due to the improper use, then how can we repair the dc cooling fan?
Maintenance method of dc cooling fan, open dc cooling fan, check item winding coil and the circuit board.
We first use multimeter to detect the stand or fall of three coil winding, if do not have bad, dc cooling fan with a multimeter test small circuit board the stand or fall of each components.
Dc cooling fans too much dirt on the blades can form equipment damage, so should use dry cotton dips in take a small amount of alcohol to wipe off the dust on the blade, then pulled open the red seal on the reverse of the fan, to smooth a few drops of oil, dc cooling fan, oil bearing and ball bearing type two varieties, smooth oil alternative sewing machine oil, south put drying after the heat sink on the lid on dc cooling fan, radiator breeze fan clean, after the end of screw twist.
Install clean good dc cooling fan radiator parts always want to put the old thermal conductivity silicone grease on the surface of the CPU clear off, with a new thermal conductive silicone installed radiator, plug in the power supply plug.
Often do die maintenance, including dust, smooth give fan axis sewing machine oil.
About how to repair the dc cooling fans this problem, here small make up to answer questions, in addition, we also need to pay attention to the dc cooling fan and try not to have a shelter, which increases the fan running time, will also affect the use of its performance.
