What kind of grease should I use in fans, for brushless and ball bearing?

Re: Grease for ventilator
http://www.BobisTheOilGuy.com will have the definitive answer.
I've read that if the orignal ball bearing can't be cleaned out completely, then lithium grease should be used because the original grease was probably that type, and mixing different types of grease can be risky. OTOH sleeve bearings should never be greased, only oiled, and oilites should never be lubed with anything. -

Laptop:
Hello, I have a System76 Gazelle laptop (model gaze14) which now only partially powers on and does not boot properly.
History:
This laptop has served me well for a few years. It's always been a bit noisy with the fans and recently became much more so on both fans, where just opening a vim/notepad session would cause the fans to spin up loudly and make a grating sound, like the ball bearing were mechanically wearing out. So after blowing the dust out of the fans out didn't help, I ordered replacement fans and heat sink component from System76 which were sold... -
The PCB motor for 1987 Technics SLP-120 CD player has slow spin-up issues. Similar to what another tech in the below video reported.

I replaced the three bi-polar 47uF electros but that made no difference. The orig three bi-polar 47uF electros tested okay on my ESR M-tester.
I have not tested/replaced those alum. SMD electro PCB caps.
Are Al smd caps are more prone to failure (or degradation) than regular thru-hole electros?

Hi everyone, I have a brushless motor, of which I am attaching a photo mounted on a DEWALT battery saw that has a faulty controller driver but with the windings ok. I would like to feed it with another controller driver (after having obviously removed the broken one mounted on the base of the motor ) but I don't have clear ideas about it. I've seen many controllers on Aliexpress but I don't know which one to get. It should have a locking system like the original one in case of engine jam.
Can you help me?

As mentioned in the build quality pictorial thread for this PSU, I got a Sparkle Power / SPI FPS400-60GN for recapping. The unit had only one failed cap: a Teapo SC 16V, 3300 uF on the 12V rail. All other output caps were okay. But since pretty much every cap in this PSU was a Teapo (and SC series for the output rails), and since the owner requested a full recap, that’s what I did.
Here is a full list of the electrolytic capacitors found in this PSU (minus the big input-side primaries):
* 3.3V rail [capacitors C24 & C25]: 2x Teapo SC, 10V, 6800 uF, 12.5 x 40 mm ^^...
