With a stock kernel now: a. when hw.setperf is set to 100, and wireless is on hw.sensors.acpitz0.temp0=78.05 degC (zone temperature) hw.sensors.acpitz1.temp0=76.05 degC (zone temperature) hw.sensors.cpu0.temp0=76.00 degC hw.sensors.wpi0.raw0=154 (temperature 0 - 285) hw.sensors.aps0.temp0=56.00 degC hw.sensors.aps0.temp1=56.00 degC b. when hw.setperf is set to 0, and wireless is on hw.sensors.acpitz0.temp0=53.05 degC (zone temperature) hw.sensors.acpitz1.temp0=52.05 degC (zone temperature) hw.sensors.cpu0.temp0=52.00 degC hw.sensors.wpi0.raw0=146 (temperature 0 - 285) hw.sensors.aps0.temp0=54.00 degC hw.sensors.aps0.temp1=54.00 degC setperf from 100 to 0 decreases the CPU temperature from 76 degC to 52, while there is no appreciable change in that of wpi0, from 154 to 146. For both readings, machine was idle with no human-user activity. The relevant dmesg is put up here http://www.obscure.org/~amunix/tmp/dmesg.bsd.mp.4.4 Any pointers to troubleshoot this issue appreciated. Thanks in advance! -Amarendra
