Question

Hello,&nbsp;After almost seven years 24/7 the fans of the GS728TP switch are getting more and more noisy.&nbsp;What are the right spare fan models and where can I buy them?

&gt; What are the right spare fan models and where can I buy them?&nbsp;&nbsp;&nbsp; I have no idea.&nbsp; I'd look at the actual fans, and then search thisnew Inter-Web thing to find suitable replacement parts.&nbsp; Having adrop-in spare network switch can make this more convenient.&nbsp;&gt; Model: GS728TP|ProSafe 24 ports PoE Smart switch with 8 PoE+ ports&nbsp;&nbsp;&nbsp; I don't use use "Smart" or PoE, so I haven't looked, but, for my simpleunmanaged switches, I've avoided models with fans for a long time.&nbsp;&nbsp;&nbsp; In an emergency, I've managed to do some disassembly, cleaning, andinsinuation of a drop of oil into the occasional dying fan.&nbsp; It was mucheasier in the days of 5.25-inch fans, I'll admit.&nbsp; Remarkably effective,in many cases, however, even for newer/smaller ones.&nbsp;&nbsp; Possibly a more appropriate venue:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; https://community.netgear.com/t5/x/bd-p/business-smart-plus-click-switches

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.

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.

[...]&nbsp;&nbsp;&nbsp; And I couldn't replace that label with a piece of tape?&nbsp;&gt; [...] placing the lubrication where it needs to be, [...]&nbsp;&nbsp;&nbsp; Well, duh.&nbsp; Perhaps _you_ can't do this job correctly.&nbsp; That doesn'tprove that others also can't.
