I’m using HP 14s since the past 4 years. The noise has started to make noise, I opened the laptop and cleaned the dust, wondering if it was causing the noise. But it still makes the noise. Can you help me figure out if everything is okay with my fan (or is it broken/or wore out because it aged)? Should I replace it?
Can temporarily fix it with a drop of oil. Pop the fan off the winding and put a tiny drop of oil on the shaft and reassemble. I did it yesterday and even successfully reused dried up compound by adding a drop of oil and reapplying it.
