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 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 buildworl= d 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: 221= 4 > > > I put the problem PowerMac G5 quad-core in a about 56degF room in order t= o try to have it run longer so I could collect more information.
