The discussion centers on effective lubrication methods for sticky fans in PCs and air purifiers. Participants recommend using "sewing machine oil" and "3-IN-ONE oil," specifically the blue label mineral-based version, as suitable lubricants. The conversation also highlights the potential issue of fans hitting the frame, which can lead to noise and imbalance. Users suggest that while waiting for the fan to wear down may seem like a solution, repositioning the fan or replacing it is a more reliable approach.
PREREQUISITESThis discussion is beneficial for PC builders, electronics enthusiasts, and maintenance technicians looking to troubleshoot and maintain fan systems in computers and air purifiers.
-Job- said:I guess the fan must be hitting the frame. If that is the case then it sounds fixable and might go away eventually after the fan wears out whatever it is hitting on or vice versa. This reminds me of when i was a kid and my bycicle's right pedal kept hitting against the bycicle's frame, it would make a lot noise, but i kept on riding it even though the pedal would stop when it hit the frame so i had to really put some effort with my right foot on the way down so that it go past the frame. Eventually it wore out about 1cm of the frame after which point it worked perfectly. There's your solution right there.
I am not sure it is hitting the frame, though. I will take a closer look. . If it's hitting the frame i would try to position/shape the fan so that it does not, buy a new one, or get one from an old computer.
