@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 Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
