PCU fan making a weird noise

I have a Fortron 350w PSU that's a few years old and recently the fan has
started making this weird mechanical noise. I tried taking it apart, but
there's no way the fan can be removed. I tried lowering the speed of the
fan, but that didn't help.

Would it be advisable to maybe try to carefully spray the gears with some
WD-40?

Thanks.

Better to use fine machine oil, not WD40.

Why can't you remove the fan?

What gears? I must admit I've not seen a PSU or case fan that's ever had
gears in it? Anyhow, why can't the fan be removed?

Yeah the gears that are on the wheel that the hamster runs in that turns the
fan,,,,

? this would be the first fan I've seen on a PSU that is not removable

your getting scary now....you meant the bearing...but then there may be a
'bearingless' fan in it. It could help to lube the bearing/sleeve, most
times its the accumulation of dirt/dust that causes it to 'whine'.

If it's one of those, perhaps it's only the hamster that needs
replacement. Does anyone know what a hamster's MTBF is?

The fan is attached to the case with either screws (most common) or
rubbery shock mounts. The latter have to be squeezed with pliers
so they can be pulled through their mounting holes.

WD-40 isn't a lubricant but a penetrant (not a very good one), water
removal chemical, and corrosion protectant. Use 5 weight mineral
oil instead, but only on sleeve bearings, not ball bearings, which need
grease instead and are usually sealed. The rear sleeve bearing can
be lubed by simply removing the label, but the front one requires
disassembly, and frankly this seems beyond your abilities.

No offense, but if you think there are gears in the fan then you
shouldn't be fooling with a power supply because you could get in
trouble with the high voltage parts of the power supply.

Don't be silly. ATX specificatons require a direct drive hamster wheel.

The most common mistake case modders make with hamster cooling systems is
adding extra vent holes, especially near the running wheel, thinking it'll
improve ventilation but the holes also let in light and the hamster, being
nocturnal, stops running.

I thought that was what the duct tape was for.

Dammit David you are just trolling again repeating crap that everyone
already knows or should know.

Well, shoot. I keep getting in trouble helping folks with what they don't
know so I figured this was safer ;)

But I guess there's no point in bringing up the hamster bean gas rear
exhaust jet 'turbo' mod, then.

whhoo weee that mod left a big brown stain on the wall behind the case, I
recommend a gas bender on the turbo exhaust vent if your going to use that
mod.

Too much bean results in that kind of 'instability'. When 'over gassing'
hamsters you should increase the bean count in small increments.

You can also mix a bit of corn with the beans to help stabilize the gassing,
but since they don't completely digest corn, you must be careful about the
occasional projectile..........

But if you can somehow harness the projectiles I know for a fact they
can be used as fuel to make those Intel CPU's run faster.
