7200 rpm

sorry blob but they are fake

No they're not. The information is provided by S.M.A.R.T.

SpeedFan reports the PC hdd to be at 29 degrees celcius. This makes sense since this PC has most cooling in it.

The peg1 linux box:

peg1:~/ smartctl -A /dev/hda | grep Temperature_Celsius
194 Temperature_Celsius     0x0022   110   253   000    Old_age   Always       -
      33

...that is, the hdd is running at 33 degrees.


Pegasos II hdds run at 43 and 44 degrees atm. This is because the machine has minimal cooling. Even 44 is still well below the maximum recommended operational temperature.

Is impossible that whatever device, could run on a 6-7 degrees more the ambient themperature.

Why would it be impossible? It depends on the cooling.

@Framiga

I personally, use a Themp/probe meter (hardware) and i've always found the the various themperature reports (don't care if on PC-Peg-AOne) are almost fake.

I guess you missed blobrana's comment:

and also via a temp sensor attached under the cover
of the HD

reports (don't care if on PC-Peg-AOne) are almost fake.

And I've found that using uncalibrated temperature sensors is always a bad idea.

S.M.A.R.T drive sensors are at least calibrated, and temp measured inside the drive, rather than somewhere outside where the airflow can affect the result.

I haven't so far seen radically wrong readings from S.M.A.R.T.

i gues that you want to litigue (as in your habit) and not and not to discuss/speak civilly.

Anyway. Back to the topic.

All 'newer' HDDs work with 7200 rpm and get very hot.

Not all hard drives. For example Seagate Barracuda 7200 remain <45 C with about 20 C ambient, and no airflow except PSU.

Many Amiga IDE and SCSI controllers can have HDD mounted directly on card. Can that heat damage the controller?

Actually I'd be more concerned about the drive itself, rather than the controller. If the drive remains under the recommended maximum temperature, then there is no problem (for the controller either).

I suggest you refer to the manual (online or physical) of the harddrive in question and mount a temperature sensor to figure out if the temp raises above the max with some stress test (copy lots of files around for example).

If it stays below the max, you're safe.

If the temperature gets close to the limit or even above it, then you should arrange some extra cooling. In most cases adding a fan is enough. In some rare occasions special harddrive cooler kit (HDD heatsink enclosure + fan) might be needed.
