Fwd: Fan control ?

[nse]

ouch.... should have gotten to the list... but got to Brad only....

and yes! i
the iSCSI is overkill... but I intend to use it ... " a little  
later" ....
Anyhow... the fan is/was on regardless of the iSCSI ...

The best thing is to isolate the unneeded parts all at once and go on
turning them on one by one.

Also, it would be useful if you could drop into single user mode to get
rid of all those Desktop Environment crap.

Unfortunately, the ondemand and conservative drivers most probably won't
work with your computer (it may complain about too high latency to
switch speeds---heck it even does that on my Pentium D 805).

Which filesystems are you using? Ext2? Ext3? You can drop the unneeded

You seem to have many access to the disk. Perhaps, you could track down
what is using the disc with:

echo 1 > /proc/sys/vm/block_dump

(Warning, this may generate copious amounts of output!)

Those suggestions from powertop are very good measures to take if you
are chasing something that you don't really understand.

Anyway, I suggest that you think about the points that I listed above
(after all, you know your needs). There's no need to justify your uses.
I'm just bringing them to your attention.

OTOH, seeing if the fan is turned on even when you remove some modules
and in single user mode would help a lot (as root, run: "telinit 1").
Running powertop while in single user mode would also help.


Regards, Rogério Brito.

Hi Rogério
You ask ... correctly .. whether I really do net those services,,, and  
yes! there are a few that can be stopped !
But the intention of using an old Powerbook was ..... as this _is_ a  
mail-server, web-server and file-server..... that it would be quiet!

I also have a "Mystic" (dual G4 450 Mhz box).. that might be more  
suited.. in particular as the fan is on all the time...
but not so noisy as compared to the TiBook

But definitely.... will try the various suggestions.. when I am  
back ...... _close_ to the TiBook! ;-)

For such uses, you can even remove the fan ;-)

Hi
In connection with this......

1. Being at a remote site at the moment... any way to tell if the fan  
is on ?? (if I was standing next to it.. it would be dead-
simple.... ;-) )

2. Anyone that has any experience with changing the powersupply fan  
for a quieter replacement in a Mystic, Medusa2(dual 450Mhz) or  
Snakebite(dual 500Mhz) ??
