Years of use computer, who is not burned several CPU cooling fan or the power supply fan? I also like, corner several burned CPU cooling fan abandoned really pity, why not try to fix the disassembly, perhaps can use waste! Cooling fan is damaged, nothing more than the coil burnt, circuit board of transistor, bearing burned out due to lack of oil caused the cooling fan is stuck or for cooling fan too much dust is clamped etc.. From the author of a dozen fan (including power supply fan) removal, or the damage reason is lack of oil, or dust, because the coil of reason of damage with no one. One CPU cooling fan, due to lack of lubrication cooling fan stops rotating, coil heat have issued a burned taste, even the colors are become dark red, but after repair the following process, and the new cooling fan is still.

First the heat radiating fan removed from the heat sink, the center part of cooling fan in the face of fin side, are generally a piece of adhesive paper round stick, off the self-adhesive paper, circular cooling fan center was out. Central bearing on the cards in a small "C" shaped plastic card, the clip that need to be removed, otherwise, the motor rotor (including cooling fan blade) cannot be removed. This small clip can use two sharp things with down. Please be sure to keep it, and don't lose it. Then, one hand holds the heat radiating fan blade, the other hand holding the fan frame back, such, can make the motor stator and rotor separated. Have a look the stator coil carefully first, as long as there is no burning, peeling, generally normal use. The following have to do is to the bearing cleaning and oiling. Must be thoroughly clean the cooling fan before refueling refueling, or directly after the cooling fan will extremely unstable. Method is the first stator and rotor dust, and then cleaning. Cleaning method of rotor is the first axis of the root of the "O" shaped rubber ring and remove, anhydrous alcohol to clean it, and then the rotor into the removed with cotton scrubbed clean alcohol, set into the "O" shaped rubber ring, put aside dry stand-by. Since then, and cleaning of the stator. Should pay attention to wash the stator coil, cannot make contact with alcohol, otherwise the coil surface of the paint film will be dissolved, causing the coil damage. Method is to use a very small amount of absorbent cotton wrapped around a toothpick, dip in on alcohol into the stator copper sleeve wipe repeatedly, until the clean so far. Until the alcohol evaporates after the copper sleeve two drops of high quality oil, the rotor shaft is a drop, not too much. Do not use sewing machine oil, because the oil will dry in a relatively short period of time, if no oil, sesame oil can be used instead of home. Finally combined stator and rotor, the placement of the clip. The middle hole on the tape, to prevent the ash inlet, and then the cooling fan fixed on the radiating fin can be normal use.
