Dear all,
if you have access to a G5 Powermac, could you provide the output of the
following command from the OpenFirmware prompt:
dev u3/i2c/fan
" .status" " u3/i2c/fan" open-dev $call-method=20
On a PowerMac7,3 having liquid cooling have access to, I get:
0 > dev u3/i2c/fan ok
0 > " .status" " u3/i2c/fan" open-dev $call-method=20
FCU Version: 6.0.1f0
Failed RPM Channel(s): 0=20
Available RPM Channel(s): 0 1 2 3 4 5 6=20
Active RPM Channel(s): 1 2 3 4 5 6=20
Failed PWM Channel(s): None
Available PWM Channel(s): 1 2=20
Active PWM Channel(s): 1 2=20
Processor A Intake Fan (RPM3): 1449 RPM
Processor A Exhaust Fan (RPM4): 1497 RPM
Processor B Intake Fan (RPM5): 1452 RPM
Processor B Exhaust Fan (RPM6): 1501 RPM
U3 Zone Fan (PWM1): 1878 RPM
PCI Zone Fan (PWM2): 1830 RPM
Drive Bay Fan (RPM2): 1498 RPM
ok
I'm interested in the RPM channels which are reported as =
Failed/Available/Active.
Please provide also some information what kind of PowerMac G5 it is.
Thanks for your help.
Best regards
