I have MintPPC 11 installed on an iBook G4. The CPU fan is running at maximum speed--kinda noisy. Anyone have an idea why this is happening and how I could fix it? Thanks in advance!

You can try to add

to /etc/modules


add at the end the line

CTRl-X and "y" to save, reboot

JD & RD: I also have had this issue, for instance, right now, with the smilies blinking on the left the fan starts blowing . . . and it is a distraction . . . I checked the /etc/modules and the "therm_adt746x" is there, just not at the bottom of the list, but in the middle . . . but still the fan is spinning madly . . . . But I noticed on the boot as the command line stuff is running the line "therm_adt746x is deprecated, plaese try to find another way" to???? (can't remember, but it went through it three or four times) . . . . Any thoughts on why that would be showing up? There is NO # in front of the "therm_adt746x" in the /etc/modules . . . but somehow, it's been "deprecated"???? This fan thing kind of reduces the enthusiasm for running the iBook in 11 . . . I like a quiet machine . . . machines should know their place . . . . : - ))))

e.e.p.

stupid answer maybe, but what happens if you comment this module out (so when you put a # before that line) ? It is also possible that pbbuttonsd takes care of the CPUfan instead of this kernel module...

JD: I suppose that adding the # in front could just as easily be undone, so there would be no "permanent" damage if that is changed. But, seeing as how that comment to the kernel saying that "thermxxxx is deprecated" may support the fact that it doesn't control the fan . . . and it might be that "pbbuttonsd" does that . . . but, then, how can we check that? what or where would we modify the "pbbuttonsd"????

e.e.p.

the only easy way to control pbbuttonsd is with powerprefs, a small utility under Menu -> Preferences. Don't know if you can set the FAN there though. I am working on an iMAc G5 mostly. pbbuttonsd does not run on this machine.

Well that depends on on how long you run your iBook without that #. Deprecated message is not for you, but a reminder to the kernel people to alter the code.

@ojordan: OK, thanks for the clarification on the deprecated message . . . but, what are you saying about the #?? That it should be there?? JD suggested adding the code "thermxxxx" line to the /etc/modules" . . . nothing about putting a # in front of it. But you are suggesting that I would want the # added?? which seems to mean that the command is to be blocked or "deprecated"?? When you say, "it depends on how long you run the iBook w/o that #" . . . it seems to be saying that I want the there??? since the "thermxxxx" line was previously already in the /etc/modules file when the fan is having its hissy fit, so I therefore want to do the opposite and ### it out . . .??? And then, why don't I just simply remove it, instead of putting the # in front???

Anyway, thanks for the insights, just wondering, didn't have time to get back to check the "pbbuttonsd" suggestion to see if there is any effect on the fan there yet.

e.e.p.

eep, sorry it should of been with that #!!

i.e. Running a G4 ibook without the thermadt746x module is bad for its health.

@ojordan: OK, thanks for the followup . . . hopefully the OP "RB" has either fixed his fan issues or is learning something from my ignorance, but this is slightly confusing. In my installation the "thermadt746x" line is listed in the /etc/modules list with 3 or 4 other items. None of them had a # in front of them, but in the "nano" file, I believe it said something like if adding the "#" in front that would "comment out" the line???, so that means to me that it would "erase" it?? But, you seem to be saying that I want the # in front of the thermxxx, also it's not good to run the computer w/o it? Certainly it would appear to be a simple fix to do either, but the question is which one? Do I want "thermadt746x" listed, in this case in the middle of a couple other items, not the bottom as JD said to add it in, . . . and leave it as it is, but maybe check the pbuttonsd app for something with the fan?? OR, do I want to add the # in front of the "thermadt746x" . . . but not the other items . . . and then see whether that does the right thing or helps the computer?? To me "commenting out" means to remove, and like I was asking in my previous post, if adding a # in front of the line "removes" the module, why then don't I just edit the "thermxx" out altogether??? unless adding the # is actually "activating" the function of the module?? I'm seeming to get two different messages between ojordan and JD???? don't know which . . . . I'm away from that computer for a few days, so there is some time for clarifying--it would be helpful to not have the fan blowing like a banshee whenever some smilies come onto the screen . . . .
