Hi Mark, All I can offer to this is a "Me Too". With OS X, running 32 python 'while True: pass' instances, core temperature never once got above 75C, but with FreeBSD, ports building repeatedly caused shutdowns. It's possible, I guess, that we are misreading the sensors, but I'm not certain at all. This happens with both of my quads. I thought maybe the LCS just needs recharged, but seeing your message, it might be a FreeBSD issue. Nathan, can you comment on this? - Justin On Thu, Jan 15, 2015 at 2:33 PM, Mark Millard <markmi@dsl-only.net> wrote: > For a well-operating PowerMac G5 quad-core for recording over 30 minutes, sampling about once a second, starting idle and doing "make -j 8 buildworld buildkernel": > > Low value to high value (for type of value to get idea of range expected)... > > dev.smusat.0.cpu_a0_diode_temp: 38.8C to dev.smusat.1.cpu_b1_diode_temp: 68.7C > > dev.smu.0.fans.cpu_a_intake.rpm: 484 to dev.smu.0.fans.cpu_a_intake.rpm: 1549 > > dev.smu.0.fans.cpu_a_pump.rpm: 1235 to dev.smu.0.fans.cpu_a_pump.rpm: 2214 > > > I put the problem PowerMac G5 quad-core in a about 56degF room in order to try to have it run longer so I could collect more information. This seems to have been enough to keep it somewhat below 90degC generally for the CPU diodes over the initial 30 minutes of "make -j 8 buildworld buildkernel". > > Low value to high value (for type of value to get idea of range happening, limited to the first 30 minutes or so)... > > dev.smusat.0.cpu_a0_diode_temp: 38.2C to dev.smusat.0.cpu_a1_diode_temp: 90.2C > (Just one 90.2C at that point and one dev.smusat.0.cpu_a1_diode_temp: 90.1C but a bunch of 89.[5-9]C's.) > > dev.smu.0.fans.cpu_a_intake.rpm: 485 to dev.smu.0.fans.cpu_a_intake.rpm: 3184 > > dev.smu.0.fans.cpu_a_pump.rpm: 1254 to dev.smu.0.fans.cpu_a_pump.rpm: 3636 > > Letting it run longer, however, has lead to more 90.[0-9]C's and messages like (all but the 1st two are from after the 30 minutes): > > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.2 C) exceeds critical temperature (90.0 C); count=1 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds critical temperature (90.0 C); count=1 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds critical temperature (90.0 C); count=1 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.2 C) exceeds critical temperature (90.0 C); count=2 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.4 C) exceeds critical temperature (90.0 C); count=3 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.6 C) exceeds critical temperature (90.0 C); count=4 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.4 C) exceeds critical temperature (90.0 C); count=1 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.4 C) exceeds critical temperature (90.0 C); count=2 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds critical temperature (90.0 C); count=3 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds critical temperature (90.0 C); count=2 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds critical temperature (90.0 C); count=3 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds critical temperature (90.0 C); count=1 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds critical temperature (90.0 C); count=1 > WARNING: Current temperature (CPU A1 DIODE TEMP: 90.6 C) exceeds critical temperature (90.0 C); count=2 > > It did automatically shut down after about 50 min. The other 3 CPU diodes were in the range 68C to 74C or so. A1 just seems to register hotter.
