We eliminate the noise (rustling, rattling) of the fan 6-23-AW15E-011 (ab7905hx-de3) of the Dexp atlas h116 laptop.
The ab7905hx-de3 fans were installed on various models of laptops on the Clevo platform (DNS, DEXP, MSI), each model has its own type of fan with the corresponding markings: 6-23-AW15E-010, 6-23-AW15E-011, 6-31 -W150N-201, 6-31-W370S-101 Outwardly, as I understand it, they are the same, the only difference is the length of the power wiring.
Once there was a time that the fan disgusting rustling. Usually the problem is solved elementary - grease. Try to understand it, it did not work. I read the forums learned that the jamb with rustling these fans (including new) happens sometimes, but they allegedly CIP, and just like that it does not lubricate. Only in one place I came to the elementary advice. To disassemble, simply pliers that clamp the impeller in the center and pull firmly, it disconnects, without risk to break off the fragile blades.
Phased for Dexp atlas h116:
1. Unscrew the back cover of the laptop. Ease of access to the insides of the laptop is one of the big advantages of Dexp-s, two bolts were unscrewed and the lid was shifted to the side
2. Unscrew the fan itself (bolts 1,2,3 in the photo), carefully disconnect the power cable
3. Unscrew the 4 bolts (in the photo 4,5,6,7) at the iron fan cover. Everything, then we pick up suitable pliers (not all will fit), with which you can reliably hold the center of the impeller and pull with effort, we are not afraid. Cotton and fan disassembled.
4. Lubricate the bushing (I use ordinary gear oil for a car) and assemble everything back. Enjoy the quiet fan again. :)
