Hi all,

I suspect a fan on my macbook is dying and causing overheating. I would like to make a record/log of fan speeds and wonder if istat menus and/or istat pro can help me. Does istat either keep a log of data values or access one created by the OS?

If the answer is no, does anyone know of a way I might be able to easily access this data directly and make my own log? perhaps there is a command line tool that returns the fan speed etc? I don't need to make plots etc in real time, just need evidence over time that the fan is dying.

Cheers,

Bump!

Hi,
None of the iStat products log any data. There is a command line tool that can give you fan speed info.

We didnt make that one but we have been planning to make some command line apps in the future but that one might help you out for now

Thanks for your help, that's exactly what I wanted.

It was easy to write a script that strips the info I need from smc's output and logs it. Diagnosis here I come.
