Isn't there a Solaris acpi kernel module (tzmon) that in theory could enable (cpu / case) fans when a thermal zone is getting hot or is overheating?Are there any error or warning messages from the "tzmon" kernel module logged to /var/adm/messages?
The tzmon-module is actually the part of the kernel which reboots the system. Well, it would in absence of the debugger: bash-3.2$ tail minicom.cap [...] WARNING: tzmon: Thermal zone (\_TZ_.THM1) is critically hot (99 C); initiating r apid shutdown [1]> :c Press any key to reboot. Resetting... [EoF]
Yep, it does. Add some time stamps and we'll get a nice temp/time graph. It's output (and the whole ::msgbuf after the "shutdown") is attached. I guess "\_TZ_.THM0" is the GPU (it's cooler until heat spreads through the shared heatpipe and the critical temp is higher) and "\_TZ.THM1" the CPU. But it's at 75°C with almost no load and at the lowest frequency:The attached dtrace script monitors the temperature for each thermal zone, as seen by the "tzmon" kernel module. Does it produce any output on your T60p?

It takes some time to heat the CPU up or cool it down and it's already running pretty fast without load...
