As a follow up to some of the earlier discussion here I tested (more
qualitatively than quantitatively) the bahaviour of the fans under OS
X by looking at the output of smcFanControl and Tempearture Monitor
(the latter displays the output of 11 temperature sensors as opposed
to the 6 exposed in Li

It would be nice to have the OS X data for temperature vs fan speed to
compare. Nicolas I've looked over the apple SMC code to try and
figure out which temperature monitor is which but all I can see is
that you read them out by some keys:
"TB0T", "TC0D", "TC0P", "Th0H", "Ts0P", "Th1H", "Ts1P", NU
I've attached a simple bash script (and a gif of some plots) for all
your enjoyment. You can just run it as follows:
mkdir power_data
poll_temp.sh first_run
This creates a directory power_data/first_run and in that directory
puts a bunch of files with temperatures, fan speeds and load as
report

I run Bresink Hardwaremonitor for some hours now. What I see so far: CPU

I wrote my last email before seeing this response of yours. Perhaps
this result of yours verifies Marios hypothesis that OS X configures
the SMC at boot time and then just leaves it that way. When you say
booted OS X and then returned to Linux did you mean started OS X and

Nicolas, sorry if I misquoted you ... I was just trying to convey my
understanding of what you said.
I'm in OS X now with my GPU heatsink at 51 C and my GPU at 48 C and
both fans hovering at 2000 rpms so its curious that Sven's rev up at
this temperature. To get my fans to start in OS X I really

Not what I said
Yes, this is quite reminicent of my experience with the fans. I
thought it might be lag on stuff that I did earlier but I'm not sure.
Nicolas has suggested that the SMC uses additional temperature
monitors that are not exposed by the applesmc module. Perhaps the
machine is just somehow heating up

Hi Sven,
Thanks for the detailed info. Its good to hear that someone with a
C2D has a quiet machine. Could you also post your kernel config? I
don't have most of those modules loaded but I'm using someone elses
kernel config that they posted and I'm guessing most of those modules

I'm on a MBP C2D.

Yes. As you've mentioned there is no obvious correlation with load
Hi All,
First ATI just released new drivers (8.35.5). Anyone have the energy
to check whether they support powerplay on C2D MBPs (it only supports
2.6.20 on fedora but next month's release should support it in general
- of course by then I'll have moved to 2.6.21 for dynticks)?
