I've got a fan in a laptop that occasionally makes some loud airplane-like noises. It mostly happens about 10 seconds after booting up and lasts for 10-20 seconds.
It also occasionally happens when the computer is running, but very rarely. Interestingly, it does not seem to happen when the processor is being used heavily.
The laptop does not have a discrete graphics card.
The fan is clean.
I'm not sure if the laptop is under warranty, but I trust my own skills much more than I trust the manufacturer (or the shipper).
Before I search for a matching fan and replace it, I thought I would see if it is safe to try any lubricants.
Are there any lubricants that are safe to use inside a laptop?
I don't want a fire or anything that will splatter and cause conductivity issues within the circuitry.
