[TenTec] Lubricating Orion II Heat Sink Fan

[Michael Tortorella]

I can't help inserting 2 cents here.  The fan manufacturers make tens of
millions, maybe hundreds of millions of these, and they are not going to add
even a penny of cost to each one if they can possibly avoid it.  And they
can avoid it by not putting in a zerk fitting that would, among other
things, ruin their replacement business.  In a way, it's perverse and an
abuse of Earth's finite resources, but that is the way we seem to have
chosen to organize our economy.  This probably bears more rational thought
and discussion but I'll leave it here for now.
73, Mike W2IY

Ah! Yes. Like Zirk fittings on all the things that ought to have them! 

Honestly, this is the first time I've been unable to get oil into a muffin
fan by simply lifting the labels.

it's our time that's most precious. Which is why I decided fixing the fan
was costing more than I was willing to pay...

behold! -- it was quiet. This one turns in the opposite direction, but that
doesn't matter. I looked it up and, not only does it have ball bearings, but
it moves even more air (27 cfm vs 25 cfm) and uses less current (0.14 A
instead of 0.23 A). If yours wakes you up with a surprising squeal, get
anything of the stated size with ball bearings and replace the old one! It's
not worth your time to keep trying to resurrect the original one.
