The case I have (Antec P183) is well ventilated with 2 large 120mm fans, plus PSU fan. 1 drive is in the middle of the case (boot drive), the other 2 are in the lower bay and get cooled via the airflow that the PSU draws in (recordings1 & 2).

Boot drive shows current temp as 26° with lifetime min/max as 21/28
recordings1 shows current temp as 32° with lifetime min/max as 25/35
recordings2 shows current temp as 29° with lifetime min/max as 23/30

so they all seem quite reasonable for HDDs.

I've got the gnome panel showing the HDD temps as well as the CPU temps, useful for the odd time I 'm using the desktop rather than in the Myth frontend.  But unfortunately when it locks up I have no way of getting to see them. 8(

I'd spent hours before then, sweated over restoring databases that had corrupted in the reboots/lockups or segfaults (I can't really remember which errors) and a quick replacement of the MB/CPU/RAM confirmed it wasn't them. (I kept the new dual core setup, only cost me about $380 all up) - Had already put a big new PS in.

Do you know what temps your drives reached?
