That obviously varys with the cooling they are getting.

You'll find some get stinking hot surprisingly quickly
when run loose on the desktop when debugging things.

Removing the cover made it run as cool as the others.

Not if you run it loose on the desktop it doesnt.

I did run all of them on a desktop, actually with the circuit boards
facing upward and the drives sitting on horizontal pencils to allow
for air circulation. I put the drives near the center of the desk
and rearranged them because I found that even small changes in air
flow would affect temperatures (a CPU fan 4" away made a chip on a
Maxtor cool from 68C to 55C, and simply sitting the drive
vertically had a similar effect).

Then I dont believe your claim that they all ran at the same temp.

What were your own results for 7200 RPM drives?

That the Seagates got significantly hotter than say the Samsungs.
Some of them got stinking hot in no time, you didnt even need to
measure anything, the drive was stinking hot by touch alone.

Except for my 80GB Seagate with the metal cover over
its circuit board, all my drives measured 42C, +-1C,

Dont believe it.

at the bottom screw holes of the the aluminum casting,

You should be using the SMART temp.

The drives were run for two hours before measurements
were taken for each test (idle first, sequential read later).

Easy to claim.
