Cooler repair

After you disassemble the laptop and get to the fan itself, check it with a tester to see if power is supplied to it. Typically, these are red and black wires. If not, then it's not a cooler.

So, let's check whether the rotor rotates under the influence of fingers or tweezers, for example. If it does not rotate, then this means that the cooler is clogged with various debris, dust, and it must be cleaned and then lubricated with grease, which is intended for electric motors.

In this scenario, everything is quite simple:

1. Tear off the sticker from it, carefully remove it with tweezers so as not to lose the loop that holds the rotor, then simply push the rotor out.
2. You will see a sad picture of contaminated entrails.
3. Using a brush that is previously moistened with alcohol, clean all this contaminated disgrace, and then dry thoroughly.
4. After that, do not forget to clean the very hole into which the spire is inserted from the rotor.To do this, you will need a toothpick, as well as a piece of cotton wool and alcohol.
5. After carrying out all these operations, it remains only to lubricate the rotor spire, and then assemble the cooler, following the disassembly process, but in the reverse order.

Important! If the cooler rotates well enough from the very beginning, but it does not work if there is power, most likely the armature winding is broken in it, but in this case it is easier, faster and more expedient to replace the cooler. In this case, use the instructions in a separate article. "How to install a fan in a PC?".
