Yes, after some research I've learned that one adheres the cooler to
the chassis side and mounts the drive in the case, chassis side up.

That is a good point. Manufacturers like to have their name featured
prominently on the drive and use inordinately large labels. Labels have low
thermal conductivity and interfere with the dissipation of heat. The
thermal conductivity of a wet paper bag is superior to any dry label,
especially those bigfoot labels. The wetter the better. Suggest you peal
off the label from the drive and clean the surface of all glue. Jumper
settings, ID, etc are not needed on new SCSI's as the controller sets them
so the label serves no useful purpose anymore. Just make sure that you wet
the bag periodically but avoid having it drip "down under". I personally
prefer seeing a wet t-shirt to a wet paper bag, but each to his own.

Well, which side up is best, depends on airflow. But I have had
a fan between two drives and it cooled both about equally well.
What you should do though, is monitor the temperature for a few
days and take into account that room temperature may be higher
on some days. If that gives you still reasonable numbers, your
disk should be fine.

Note how Rod repeatedly denegrates those he considers have inferior

The Aussies did indeed lose their match against Brazil, but they
still have more points than the USA after two matches.

Yea, but we got more red and yellow cards, that should count for something.
Not to mention that we even got Italy to score one goal for us. Something
the Aussies could not do to Brazil ;-)

Someone should've explained to your guys that this is the 2006

and Yellows for Air Miles to get back home on the cheap.
So you provoked a friendly-fire casualty - you should feel miffed,

Hi!
I'd tend to think that the area around the spindle motor is going to
get the hottest of anything, as there is something happening there
almost all the time.
However, the casing of most drives is going to act as a heat sink for
many of the heat generating parts that aren't on the electronic board.
With a good drive design, the heat should be distributed pretty evenly
across the whole casing.
I've done some informal testing with a Seagate Barracuda 2GB 7200RPM
SCSI drive and an infrared thermometer. The case temperature is pretty
even on this drive once it has been on for a while. This drive is of a
unique design where the electronics are on the top. The spindle motor
is also mounted "upside down" from the normal way.
For those who say that drive coolers don't work, I think you'll find
that is simply not so. Turning a conventional 12V computer fan on the
Seagate drive cooled it quite a bit. The drive itself is in a test bed
setup and usually sits in free air that isn't moved.
Of course, you do need somewhere to send the hot air to, so if your
case doesn't do a good job of moving hot air out, then even the best
drive cooler can't do much. That said, I've never felt the need to
spend the money for one. A case with good ventilation should not have
any trouble keeping the stuff inside at a safe operating temperature.
The trouble is, most of today's cases don't seem to have well defined
airflow patterns, and the fans move far too slowly to move the kind of
air that is needed.
My recommendation would be to position the cooler so that it moves air
over the top, bottom and sides of the drive equally, if possible.
