I have a mid 2004 Dual 1.8 Ghz G-5 running Tiger 4.11. When I go to
system logs on console I get a message (every second) that there is a
fan failure.
I opened the computer and visually saw all 7 fans running: i.e. 2
front fans, 1 by the front speaker, two exhaust fans, 1 cage fan by
the hard drives and one fan on my ATI 9800 video card.
To make sure the blades were turning I stuck a thin paper tube in the
blade area to see if they/it made a sound. They/it did.
I run temperature monitor and the CPU temps do not get above 129
degrees F and when they get up that high there is an increase in fan
speeds. I saw where there is some fan control by resetting the SMU,
by shutting down and then pulling the power cord for two minutes then
starting up a gain. This did seem to keep the temperatures down. I
ran Applejack which also recorded fan failure, as well as Onyx,
Macaroni, and MacJanitor.
I have seen where there are two fans on the 600W Power supply and I
was wondering if one or both of these fans could be the one not
working. I don't know if there are any other fans on the unit and if
there is a software fix for this. I used external the hard drives
from my dual 1.42Ghz G-4 MDD in this unit.
Any insights will be greatly appreciated.
