Per,
I don't know how you measured the load, but it is important to measure very short power surges. In particular, I'm suspicious of that load during raid1 resync. Could your technique catch a 10 msec spike etc? Nope, not a chance. See my reply to Carlos.
I think it is the spikes that are causing trouble with Sata drives. Don't know that, but I do know that new power supplies were not a major source or error reports on lkml. Over the last year, it is extremely routine, even with new 650W supplies. Interesting - the SATA drives have not been causing me any problems (so far), but the system is still less than stable under load.

Have you made certain you have Good thermal connection between the CPU and you heatsink this sounds like a problem i had with this machine turned out it need a cleanup and new thermal compound reseat the heatsink had no problems since might be worth a look one spec of dust just fractionally too big could cause you untold hassle
And don't use that God-awful thermal putty. Use some good thermal grease, like Zalman ZM-STG1 or Arctic Silver (Arctic Silver 5 or Arctic Silver Ceramique) The way these greases are designed, the slight vibration of the fan on the heat sink will slowly push the larger particles into the larger gaps. Thus, optimal heat transfer from CPU to heat sink will not happen initially -- this will take a couple of weeks. The Zalman is about 2x the price of a typical Silver-based grease BUT comes in a nice bottle with a fingernail polish brush in the cap so you can apply a nice even coat across both surfaces without ending up with excess oozing out all over the place. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
