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=3D1 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds = critical temperature (90.0 C); count=3D1 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds = critical temperature (90.0 C); count=3D1 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.2 C) exceeds = critical temperature (90.0 C); count=3D2 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.4 C) exceeds = critical temperature (90.0 C); count=3D3 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.6 C) exceeds = critical temperature (90.0 C); count=3D4 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.4 C) exceeds = critical temperature (90.0 C); count=3D1 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.4 C) exceeds = critical temperature (90.0 C); count=3D2 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds = critical temperature (90.0 C); count=3D3 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds = critical temperature (90.0 C); count=3D2 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds = critical temperature (90.0 C); count=3D3 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds = critical temperature (90.0 C); count=3D1 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.1 C) exceeds = critical temperature (90.0 C); count=3D1 WARNING: Current temperature (CPU A1 DIODE TEMP: 90.6 C) exceeds = critical temperature (90.0 C); count=3D2 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. It ended with the recorded sequence for a1: dev.smusat.0.cpu_a1_diode_temp: 89.2C dev.smusat.0.cpu_a1_diode_temp: 90.6C dev.smusat.0.cpu_a1_diode_temp: 90.6C dev.smusat.0.cpu_a1_diode_temp: 90.1C dev.smusat.0.cpu_a1_diode_temp: 89.9C dev.smusat.0.cpu_a1_diode_temp: 90.1C dev.smusat.0.cpu_a1_diode_temp: 90.9C dev.smusat.0.cpu_a1_diode_temp: 91.3C dev.smusat.0.cpu_a1_diode_temp: 91.1C dev.smusat.0.cpu_a1_diode_temp: 91.4C dev.smusat.0.cpu_a1_diode_temp: 91.8C dev.smusat.0.cpu_a1_diode_temp: 92.0C The high fan/pump figures recorded were: dev.smu.0.fans.cpu_b_intake.rpm: 3199 dev.smu.0.fans.cpu_a_intake.rpm: 3200 dev.smu.0.fans.cpu_b_exhaust.rpm: 3198 dev.smu.0.fans.cpu_a_exhaust.rpm: 3199 dev.smu.0.fans.cpu_a_pump.rpm: 3637 These are all well above those recorded for the well-operating PowerMac = G5 quad-core. =3D=3D=3D Mark Millard markmi at dsl-only.net
