I had a parir in a server that despitea 80mm fan and air-conditioned
server room did not cool the disks well at all. I think there was
not enough of an air-path in there. So be skeptic, even if there
is a seemingly large enough fan.

Depends on the quality of manufacturing.

Currently I don't have a source. Maybe someone else here knows.

From personal experience I agree that bottom fans are the better
solution.

This would mean that the cooling is mainly by airflow.
Not surprising.

Yes, there is little firm contact area between the hot parts
of a hard drive and the tray that it is mounted in, so any conduction
to the aluminum tray is minimal.

But I meant longevity of the plastic pieces. The other poster
is an IT consultant who recommends Athena to her clients, and
there have been no reported problems resulting from their plastic
construction.

Do you have a URL for this "Athena?"

Would not even know what to search for.

Athena Power seems to have changed its website since last
night. Now the only mobile racks with a bottom fan is this for
SATA: http://athenapower.com/sub/mr136b.htm
and this one with temperature monitoring for IDE:
http://athenapower.com/sub/mr999atn.htm

All models are aided by the case and power supply exhaust
fans, and in case of a failure of the mobile rack fan, air is still
drawn through the tray. Such are the advantages of case fans
which blow air out the back, keeping the case interior at an air
pressure lower than ambient.

Especially on the multiple fan concept, if one fan dies the drive is still
reasonably protected against overheating.

Well, at least it's a cheap and cheerful indicator that they are still working.

Which is quite enough.
I have one 40mm fan blowing on top of a 10K SCSI and it's running
on 7 Volts which is available in any tray suited for 3.5" drives

> so they spin fast.

There is no 'so' about it.
I have one 40mm fan blowing on top of a 10K SCSI and it's running

That's on top, where as the temperature sensor is on the bottom of
the drive. It runs at a nice 33C at 20C ambient.

If memory serves me right it runs somewhere in the high 40ies without it.

Silly you.

Pity then when that *single* bottom fan fails and the
rack has no protection against it, the drive cooks itself.

Personally I would look for a tray with a front air intake and back-half
bottom-and-top air outlets, so the case fan(s) can serve as alternate tray
fans.

I have to say that I had 2 of these for 4 drives each. The cooling
was completely insufficient and the backplane was manufactured
shoddily enough that I got SATA bus errors because of imprecise
trace lenghts. This was admittedly 3 years ago. I take it these
two issues are fixed in the 1 drive variant?

Arno:
I assume you've seen my posts in the pc-homebuilt newsgroup referred to
above re the Athena removable HDD mobile rack.

As far as mobile racks designed to handle two or more HDDs...

I've really had only limited experience with them - chiefly the Athena
BP-SATA3051B model (holds 5 HDDs with the unit installed in 3 bays). See...
http://www.newegg.com/Product/Product.aspx?Item=N82E16817995001

During the relatively short time we worked with that unit we didn't
experience any problems - heat-related or otherwise. I'm aware of one other
user who's been using that unit for some time now and he's satisfied with
it.

Thanks very much for the two links Timothy.

Thanks Anna that really helps.

For eight years now we have 8 machines that are equipped with DataPort
Racks and trays. Just passive cooling and they have worked liked
Champs. They also cost a lot more those days.

I should hasten to add that these drives are only used to clone the C:
drive back and forth. So they may be only on for 10-30 minutes. But
even in the room where in the summer the temperature is always in the
high nineties. Never a problem.

Thanks again I shall have a look at them.

You may also want to check out these:

1)
http://www.raidsonic.de/en/pages/products/mobile-racks.php?we_objectID=4686
and
2)
http://www.raidsonic.de/en/pages/products/external_cases.php?we_objectID=4589
or
3)
http://www.raidsonic.de/en/pages/products/external_cases.php?we_objectID=4255

I have (1) and (3) in use and am very satisfied. They are compatible to
each other, meaning, that you can swap the disks between the internal
swap-frame and the external enclosure. Build quality is high. The
external is aluminium without fan at all, the internal has a small fan,
which I, surprisingley do not really hear (in my pretty silent case).
