What is the maximum temperature a 68040 @40 mhz can tolerate?
I already read the 68040 users manual from Freescale, but then there I could not find the information I need. I want to know this since I plan to overclock it and measure its temperature with a digital thermometer with an alarm so as to know when I am reaching the absolute limit, and then stop, before I kill it.
The other thing is, where on the 68040 should i put the temperature sensor? Is the heat conducted evenly to the entire chip enclosure, or does it get hotter on the center?
40Mhz is the fastest you can push an 68040 without the need for exotic cooling methods. They're just not stable beyond that.
Tbh mate, any overclock you put on it would be negligible at best. If it's working and its stable, leave it alone. Trying to crank it up to 50Mhz is a sure fire way of causing the magic blue smoke to escape from it.
