[Found the right stuff] Axle Grease for fan in HP Pavilion Laptop
<< < (8/8)
BrianHG:
It's been another 90 days and the laptop fan still runs like new.
That's half a year.  I think we can call it fixed.
magic:
It should be OK. I use general purpose lithium bearing grease in fans and they work 24/7 for a long time. One is maybe 10~15 year old and had a few grease replacements already, still spinning and still quiet.

The only exception was one low profile, low RPM fan with a wimpy motor which was originally lubricated with some oil. Grease slowed it down to the point it couldn't start.
CapLeaker:
I also use some heavier oil that is a bit thicker, but with PTFE. I also use(d) WD40 followed with Lithium Grease before for many years no problem.
Things changed a bit when the laptops got really thin and lightweight. Their fans are really thin now. For these I just use some high quality thicker oil with PTFE and so far so good.

This stuff: Lucas White Lithium Grease

Isn't grease NLGL#2 thick? Maybe grease NLGL#1 is preferable for low-power fan axles?
