If I leave it open and on a table, everything is fine. I have a quad-core processor and MAKEOPTS="-j5". During compilation, system load is around 5 and all 4 cores are maxed out. My CPU temp is 99C or under, which is safe for this machine. dmesg shows this every few minutes whenever my machine is at max temp, which I've read is normal: [ 2092.018902] CPU0: Core temperature above threshold, cpu clock throttled (total events = 179101) [ 2092.018903] CPU2: Core temperature above threshold, cpu clock throttled (total events = 179101) [ 2092.018906] CPU3: Package temperature above threshold, cpu clock throttled (total events = 227311) [ 2092.018907] CPU1: Package temperature above threshold, cpu clock throttled (total events = 227311) [ 2092.018908] CPU2: Package temperature above threshold, cpu clock throttled (total events = 227311) [ 2092.018916] CPU0: Package temperature above threshold, cpu clock throttled (total events = 227311) [ 2092.019864] CPU0: Core temperature/speed normal [ 2092.019865] CPU2: Core temperature/speed normal [ 2092.019866] CPU1: Package temperature/speed normal [ 2092.019867] CPU3: Package temperature/speed normal [ 2092.019868] CPU2: Package temperature/speed normal [ 2092.019874] CPU0: Package temperature/speed normal [ 2099.655532] mce: [Hardware Error]: Machine check events logged At the time of crash, syslog contains a bunch of '^@^@^@^@^@^@^@...', but nothing useful. It looks like my cpu clock is being scaled, but perhaps not being scaled enough. I'm guessing the processor halts when I hit 100C. Again, when I leave it well-ventilated it never goes above 99C and everything is fine. Any ideas about where I should look?
