Hi

I know it's a very long shot but does anybody know of a very simple CPU core temperature monitoring app that will work on an x86 Mac? I have tried all the PPC based ones that I know of and unsurprisingly they didn't work. The reason I ask is that I have a dual boot machine and manual control of all 3 fans via a Vantec Nexus fan controller. It's very easy to keep track of the CPU temp in Speedfan on the PC side of things and therefore keep the fans running as quietly as possible whilst still keeping an eye on the CPU temperature. However with no way to monitor CPU temp on the Mac side of things I tend to run the fans much faster than I probably could get away with just to be on the safe side, but this leads to noise levels that I am not happy about as I am a stickler for having an ultra quiet machine where the loudest component is probably my 7200 spin HD.

I guess if I'm doing the same kind of things on the Mac side of things as I am on the PC side of things (web browsing, downloading, unraring, etc) then CPU temps are going to be pretty much the same in either OS but I would still prefer to be able to keep an eye on the CPU temp for piece of mind. I only have a Celeron D 325J at the moment with a stock HSF on it but I plan to put a midrange P4 in soon albeit with a Zalman cooler. It will be then that I will really need to know core temps. I find the thermistor that came with my case that displays CPU temp on a front panel LCD to be wildly inaccurate compared with Speedfans readings.

Would it be a huge job to knock up a quick app to display core temp? Is it as simple as reading a CPU status register? Maybe IA32_THERM_STATUS register or something similar?

Any suggestions?

Yes, now Hardware Monitor 3.2 is Universal:

But this detects no sensors on my box, so I think it is for Apple hardware only.

EDIT: Apple hardware or not , this should at least read my CPU's temperature. I now think this probably a 10.4.4 versus 10.4.3 issue.

So I am looking for anyway to read the CPU temperature in OS X. Anyone?

I have look around quite a bit for CPU temperature monitoring (outside of just rebooting and reading the BIOS data).

It looks like there are few FreeBSD utilities that could be easily ported to Darwin (if necessary):

/usr/ports/sysutils/lmmon
/usr/ports/sysutils/xmbmon
/usr/ports/sysutils/healthd

i've tried compiling them. but i'm getting an 'configure: error: installation or configuration problem: C compiler cannot create executables.' error
gonna see if i can fix this somehow.
But with no exp. at all it might take a while any tips anyone?

the error seems to be related to broken CFLAGS

just found '.include <bsd.prog.mk>' in the make file, maybe this can't be found

Has anyone tried temp monitors for Windows with Darwine?

i just tried hardware monitor, mobomonitor, and speed fan but the y couldn't read the sensors.

Thanks, is there any open source thing to read sensors?

Asus has a pretty cool moniter but it's for creepy Windows only, I think they need to get with the program and make it work on OS X and Linux.

shows no registered sensors and so does

I doubt that it is possible without writing your own sensor interface.

johnniecarcinogen how did you get speedfan for mac???


edit: nvm... i got it running in darwine but have same problem as you
grrr retarded laptop fan

So does this mean we would have to write kext using IOKit?

Perhaps, I have no experience with IOKit...

I would say that is either photoshopped or its a MAC OS Window Skin under XP. They don't make a version o SpeedFan for Mac, according to their website.

Actually it is the windows version running on OS X using Darwine.
