-
- At 400 deg Celcius the chip won't work very good - if it work at all.
- It depend a bit of how long time the chip is at this high temperature.
- I may work at 400 for a very short time, but not for any long time.
-
- If the right program exist - it won't run very long. When the
- temperature in the chip get too high, the electrical function of the
- chip begin to degrade until the temperature is down to normal again.
-
- >And the 586 is supposed to run even hotter!! Isn't that awful?
-
- Yes, and good cooling is even more required. When more heat is produced
- in the chip, more of it must be transported away from the chip to keep
- the temperature as low as possible.
