To get back to this discussion (sorry, normal job kicked me quite a bit last week).

I have been letting two instances of gnuchess playing against each other for a couple of hours (yes, I know... best stress test ever... ;-) ) which kept cpu usage at a nice 100 percent on both cores for all that time. proc/acpi/thermal_zones/THM1/temperature (and THM0) reported temperatures around 70 degrees, never over 72 for all that time. Lid was closed, fan worked (not very noisy even) and blew a good load of hot air out. I am tempted to say that my overheating problem is not hardware related. Only parts different were ath0 not working with Fedora and hard drive being not the 160 gig WD I am using for FreeBSD. > >> Only under load does the temperature >> shoot up, but I know the chip isn't getting hot and the fan >> is running - I've felt around in there and nothing was even >> close to the 117+C it was sensing. > > Apart from the actual CPU, most parts of a system have a fairly > significant thermal mass so a rapid change in temperature either > indicates a catastrophic failure or the temperature sensor isn't > really reporting the temperature of the relevant zone. > I totally agree with you, Peter. And either the hardware just fails under FreeBSD (or with ath0 and the other hard drive running) OR it is a FreeBSD problem. Everybody is invited to tell me how to stress test the system as brutal as possible to show that the problem is hardware related. Regards, Johannes
