Hi Dark,

The fan that Lambda used was anything but cheaply constructed. It
had steel cased ball bearings, and a fan good signal line. It wasn't
the fan's fault that lambda put the fans at the end of the heat sinks
and sucked the hot air through the fan. It basically cooked the grease
to death.

But, a 115V fan would have still run longer because they typically
have 16W motors, and this 12V fan was only 5W, IIRC. Since the
fan was built into the supply, its load was included in the efficiency
rating of the supply. It had two of these fans per supply, so they
were wasting around 10W out of 2KW in fans.

The supplies I last fixed were in color printing equipment used by
a large local printing firm. They had dozens of these printers, and
each had a half dozen of these power supplies. The supplies went about
5 years before the failures started showing up.

That would be so if Lambda was the only supply where I saw
12V fan problems, but it isn't. I have also run into it in the
little fans that live in PC power supplies. Only, they are
typically sleeve, rather than ball bearings.

-Chuck



There are fans, and then there are fans.

We make rack products that utilize fans and filters and they last
for years, just like a good ol' Tek scope or HP scope or analyser.

It all comes down to getting what one pays for. There are superior
brands, and even models within a brand name that is good, that get
economized, and thus fail sooner.

If Lambda bought a cheaper fan, they would have suffered for it in
field failure numbers being high. From your input, they did.

I have seen products whose fans never failed during the life span of
the product itself.

I don't economize on air handling. When fans are called for, there
is usually some heat that needs to be carried away. They, being
mechanical, need to be as reliable as possible. Brand does matter as
well.
 
Are the fans in the environment, or outside? If the fans and
their motors/bearings, etc are in the environment, then they are
special fans indeed! Running from -40C to +200C. I would never
attempt that, and would put the motors outside of the environment,
and only put the fan blades in the environment.

If they are outside of the environment, then ho hum!

That there ARE reliable fans to be had.

[snip]

Last week one of our servers at work had a bad fan, and one of the
guys pulled it out to replace it. Turned out that the replacement fan
had a foot shorter pigtail, so I had to cut off the old pigtail and
add it onto the new fan with some heat shrink tubing.

So I pulled the blades off the old fan to see what happened, and the
8-pin DIP chip on the PC board was burned up. I didn't do much
further checking because it still stunk like it was burned up.
Anyhow, I don't think that would be a problem with a simpler fan that
used a regular AC motor.

Chassis are supposed to be positive pressure. That would be fans
pushing air in, not sucking already heated air out.

Poor design.

I saw where a death-row inmate donated his body to "science." After he was
killed by lethal injection, they immediately took his body and froze it in a
block of ice. Then they took this to the lab, where they proceeded to cut it
into over a thousand "slices" with a bandsaw. Each of these slices were then
scanned into a digitizer and reconstructed into 3D. So now they have a
teaching model of a human being, that can be looked inside without any
incisions.

I guess that is a donation to science... would kinda suck to be placed back
into your casket in 1000 pieces though.

They used a CNC controlled Bridgeport milling machine. They body was
filled with liquid, and frozen solid. The milling machine removed small
layers (1 mm, I think) and they photographed what was revealed, end
on.

When they were done, there was nothing left but mill shavings. All of
the pictures are viewable on the internet at:

IIIRC, they milled off a layer, misted it with water to get a good
surface to photograph and then went on to the next.

This was done more than once. The most recent one was done with the
frozen BP. I think Scientific American did a story on it. Previously,
in the 1930s (?) it was done in cruder (maybe 1/4") slices, both to a
man and a woman. Unless it's been moved, the slices were on display
(but semi-hidden) in the Chicago Museum of Science and Industry,
appropriately sandwiched between glass sheets and pickled in
formaldehyde. The museum is well worth a visit if you're in the area.
