@Rydberg: Running the script on my MBP5,1 it says: Scanning SMC registers... Mt register found
The machine has a Mt but no Sf register. It is likely built 2009 or 2010. The SMC does not have a (known) overheat protection, so the machine might get really hot under CPU load. DO NOT rely on the SMC to automatically regulate the temperature, but use a fan control scheme known to work with your machine. --- But from experience I can say the SMC seems to regulate temperature quite well and I've never had any problems with potential dangerous overheating even under load - testing by running two instances of while true; do cat /dev/zero > /dev/null; done to max out the CPU - once the processor hits about 95C (as gauged by temp5_input from applesmc) the fans ramp up from 2000 RPM to over 3400RPM (although be it quite slowly) and which then seems to hold the CPU temp at ~85C (although it is still dropping very slowing as fan RPM increases) - output of all temp and fan sensors atm under load: a...@tokyo:~$ for t in /sys/devices/platform/applesmc.768/temp*_input; do echo $t: `cat $t`; done /sys/devices/platform/applesmc.768/temp10_input: 57500 /sys/devices/platform/applesmc.768/temp11_input: 68250 /sys/devices/platform/applesmc.768/temp12_input: 73750 /sys/devices/platform/applesmc.768/temp13_input: 73500 /sys/devices/platform/applesmc.768/temp14_input: 76250 /sys/devices/platform/applesmc.768/temp15_input: 72500 /sys/devices/platform/applesmc.768/temp16_input: 57500 /sys/devices/platform/applesmc.768/temp17_input: 65500 /sys/devices/platform/applesmc.768/temp18_input: 65750 /sys/devices/platform/applesmc.768/temp19_input: 31500 /sys/devices/platform/applesmc.768/temp1_input: 34250 /sys/devices/platform/applesmc.768/temp20_input: 50250 /sys/devices/platform/applesmc.768/temp2_input: 34250 /sys/devices/platform/applesmc.768/temp3_input: 33500 /sys/devices/platform/applesmc.768/temp4_input: 34250 /sys/devices/platform/applesmc.768/temp5_input: 85000 /sys/devices/platform/applesmc.768/temp6_input: 70000 /sys/devices/platform/applesmc.768/temp7_input: 71250 /sys/devices/platform/applesmc.768/temp8_input: 83000 /sys/devices/platform/applesmc.768/temp9_input: 66000 a...@tokyo:~$ for t in /sys/devices/platform/applesmc.768/fan*_input; do echo $t: `cat $t`; done /sys/devices/platform/applesmc.768/fan1_input: 3414 /sys/devices/platform/applesmc.768/fan2_input: 3407 a...@tokyo:~$ for t in /sys/devices/platform/applesmc.768/fan*_min; do echo $t: `cat $t`; done /sys/devices/platform/applesmc.768/fan1_min: 2000 /sys/devices/platform/applesmc.768/fan2_min: 2000 a...@tokyo:~$ for t in /sys/devices/platform/applesmc.768/fan*_manual; do echo $t: `cat $t`; done /sys/devices/platform/applesmc.768/fan1_manual: 0 /sys/devices/platform/applesmc.768/fan2_manual: 0 -- WARNING: Intrepid might burn down MacBook Pro https://bugs.launchpad.net/bugs/262550 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support.

Installing today's updates, the MacBook gets extremely hot and automatically goes into standby. This looks like an emergency standby caused by the EFI or something because it got overheated. Unless you put a metal plate or something under it, the fan runs on highest level at full power, which is not the usual. Is there a tool you can see the CPU temperature with? _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : mactel-support@lists.launchpad.net Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
