Ok, so it's been about a week that my laptop started making rattling noise. First, I thought that it might be the dust and got it cleaned, but turns out, the fan was damaged.I tried cleaning and lubricating it, but it didn't work. Also, the fan is hypro-bearing type, so maybe there's a different lubricating technique??? (Google search on this matter (lubricating such fans) yielded no results ). I tried to replace it, but couldn't find it locally (read: within the country). So, I am thinking about just shutting down the fan itself and just using the notebook cooler I have, which is pretty decent. My processor is Intel i3, so I doubt the heat production will be too much. I just want some advice on what precautions I'd need to take and whether this would be a plausible/sensible thing to do.
