Before you begin, you must make one thing clear: if you want it to look new you should completely separate and disconnect the fan. This is to be able to clean it on both sides, so that you can clean the ventilated grill inserted into it, because otherwise it will get dirty again quickly.
That said, let's go there.
How to clean the fan
If the fan is extremely dirty and full of smoke, you might as well get it compressed air removing most of the dirt. This won't leave him a complete fan though it will save us a good portion of the work
If you do not have compressed air, there is one a clean and dry brush It can also help you in this process, giving it a gentle touch with all its spots and layers.
It should also be noted that this should be done with the fan removed (unlike the one in the picture above), otherwise the dirt will go to other parts of the appliance.
Once we have been able to get rid of all the dirt, we should now get a microfiber cloth. With the extended cloth, we put it on our index finger, introduce it between two blades, and turn it around the entire edge of the inner frame
This process should be repeated on both sides to ensure the frame is cleaned internally. Once done, we can clean the outline, which is difficult.
Once this is done, we must be sure and clean the rods holding the frame on all faces, because there is a lot of dirt stored there.
We take this cleaning too, all in the same cloth, spots. Very carefully do not put too much pressure
In the end, the way to make it 100% perfect is to do the extra step, which is to include a) an ear for alcohol (For sewage, this type of plastic will not be damaged by it) and clean the edges (edges) of the stains, because even when the dirt is usually absorbed.
This same stick can help us get to the hinges or the frame where we are not well on the rope. Once this is done, we will have the fan as new and ready to be able to re-install it on the PC.
