Agreed. CRC is for freeing up 'frozen' parts only, not a lubricant per se.
I use a drop or two of Castrol VMX manual transmission oil, usually *before*
the fan gets to the siezed-up stage. Often I use it pre-emptively, before
fans show signs of trouble. However I've used it with great success on
siezed fans also, you just usually have to 'work it in there' by manually
turning the fan for a while.
I use it on the fan bearings of any laptops that I happen to have apart,
simply as a maintenance measure, as well as all readilly accessable fans in
desktops that I 're-build' before they go out the door. I find that it
prolongs the life of those little fans considerable, almost to the extent
that a small squeeze-bottle of the stuff is a must-have for anyone who works
with computer / laptop repair and maintenance.
