Temperature software? (8.1 or 7.6)

Hi...
 
I am looking for some software that might give me the temperature of my CPU, the logic board, hard drive, or anything close to that.  I am running 7.6 and 8.1 in my Color Classic .
 
I have been unable to find anything.
 
Suggestions welcome.
 
Thanks

To my knowledge, Macs this old do not have temperature sensors.

The closest you can get on, as far as I know, anything before 1998 at all, will be to install an external temperature probe of some sort and read it with a dedicated device. I don't know what type of probe would be best, but something with a somewhat long cord may be best, since the best measurement of running temperature on the CPU will come from the machine being closed up and set up how you'll normally use it.

 
Thank you Cory5412.  I do have a external device with a display and a long (small) wire with a probe on the end. I could somehow attach that to the heat sync of my CPU or maybe place it somewhere else in my Color Classic.  That is my fall back plan.  I found temperature software for OSX, but nothing for 68K macs. 

Maybe someone else knows of something.  I came up empty handed.

Thanks

No 68k Mac has a temperature sensor onboard, I'm pretty darn confident saying that. In theory I suppose if you've fitted the machine with a more modern hard drive there *might* be some way to read the sensors on that, but I suspect you'd have to write your own software to do it.

Best I can suggest is an oven meat thermometer. They're pretty cheap and have a couple feet of leash on their probes.

 
Be pretty awesome to run an arduino or some tiny modern board in there with a temperature probe and get information from it over serial.

 
I guess it all depends if you're looking for some permanent always-on solution, or just want to get a rough idea of how toasty your color classic is going to realistically get as a one-time deal. It's certainly not rocket science to do the Arduino thing. (Heck, you could use something way dumber than an Arduino. In my junk drawer I have a demo board for this dinky little Motorola SoC that's internally vaguely based on the ancient 6803 family of embedded CPUs in, what, like an 8 pin package, and it's capable of driving 1-wire bus peripherals and bitbanging serial at the same time.)

But on the other hand, well, the 68k CPUs used in those old Macs basically have nothing in the way of active power management, so unlike modern CPUs I don't think there's going to be much difference in temperature between a system just sitting there idle verses going all out generating Mandlebrot sets or whatever it is you might do to put a Color Classic through its paces. Maybe a few degrees at most? If you do the oven thermometer thing and find it's "warm, but not too warm" inside, well, don't turn it on on hot days?
