GS728TP replacement /spare fan
Hello, After almost seven years 24/7 the fans of the GS728TP switch are getting more and more noisy. What are the right spare fan models and where can I buy them?
Oil and fans are a difficult combination, you'll invariably create an oil aerosol liberally covering the insides of your device - as a result dust settles and creates a sticky matting over the internal components acting as a heat insulator (both damaging components, increasing fan noise trying to counteract and becoming a fire hazard).
Replacing the fans is usually the only real option, but I doubt these are considered to be (officially-) user-servicable, so documentating might be lacking.

"invariably"? Strange, then, that I've never observed "a drop of
oil" "liberally covering" anything, any place. Do you believe that fan
manufacturers don't use lubricants? Read it again. I didn't (and
wouldn't) recommend immersing the fan _blades_ in oil.
They do use oil (well, not always), but they use it more sparingly than most users do - and they often seal the bearings up (with the label). Furthermore they apply the lubrication in the production process, before the blades are attached, placing the lubrication where it needs to be, rather than trying to reach the bearings with the blades attached.

And I couldn't replace that label with a piece of tape?

Well, duh. Perhaps _you_ can't do this job correctly. That doesn't
prove that others also can't.
