Never lube any PC fan

Noise problem is usually caused by dust or bearing ending its lifetime.

ON CPU generally, fan are clipped or screwed on the heatsink.

But some manufacturers glue them with and thermal conductive glue.

You can try to make it turn with a vacuum cleaner and check its noise.

The problem is that I can't seem to remove it and also, after seeking
out websites suggesting lubrication a small hole, which I don't seem to
have, I am unable to lub it. The way the fan is attached to the
heatsink is by locknuts that are on the bottom of the heatsink and I
don't see any easy way to just pop off the fan and replace. The fan
itself is a Thermaltake Tt and the heatsink may be too for that matter.
Initially I tried removing the four screws holding the fan in place,
but the heatsink came out too and I had to clean and then recoat the
heatsink/ CPU before pushing and screwing the fan/heatsink assembly back
into place. This desktop is up and running as I write from it, but the
fan has become quite loud. Even if everything is off and I just spin
the fan by hand, I can hear the same vibration. Is there any way I can
just lubricate or replace the fan without also the heatsink, or is there
no choice but to have to replace them both?

Most fans have a sticker over the end of the shaft.
Some have a rubber plug over the end.

I use gun oil. It's thicker, so it tends to stay longer.
Yet it penetrates well.

For power supply fans and laptop fans, I often drill a hole
in the case so I can poke an insulin syringe thru the label
to lube it next time.

It's harder to get the lube to the other end of the shaft
for ball-bearing fans, but if you put in enough oil, it
migrates better than I expected.

Some fans don't have access to the shaft at all.
I never figured out how to remove the blade without breaking
something.
One time, I drilled a tiny hole in the blade hub at an angle
that intersected the bearing beneath and lubed that hole.
Tricky, but it worked.
