ThinkPad T61 here with 7200RPM SATA HD: # hddtemp /dev/sda /dev/sda: WDC WD3200BEKT-******: 35°C The drive has been spinning for 3-4 hours now.

I'm impressed. What airflow? On my Thinkpad ?43, without proper airflow the internal fan starts spinning loudly. -- Obsession with "preserving cultural heritage" is a racist impediment to moral, physical and intellectual progress. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

And they don't get all that hot, nothing like a CPU or GPU IC. My WD 500GB 7.2K SATA runs a pretty constant 26C (95F)--lower than core human body temperature. This is a 3.5" drive in a server vs a 2.5" drive in a laptop, but as another OP noted, his laptop 7.2K drive only runs about 10C hotter due to the constricted airflow environment. 15K rpm drives are the really hot ones. And you won't find one in a laptop any time soon. An SSD of equivalent capacity is about the same price as a 15K drive anyway and much more thermally friendly. -- Stan -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Decimal shift error that I always warn my children about. -- Obsession with "preserving cultural heritage" is a racist impediment to moral, physical and intellectual progress. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

What airflow? On my Thinkpad ?43, without proper > airflow the internal fan starts spinning loudly. What do you mean by airflow? I haven't modified the T61 case, and the fan doesn't seem to run any more often than with a 5400 RPM drive.
