- Well, I guess I stand corrected then, both by this post and a former one.
- I have not had any such experience with CPUs failing or becoming flaky
- due to temperature under "normal" (ie, someone sold it that way)
- operating conditions.
-
- So now the question is, if indeed the 486 tends to run so close to the
- 85 C limit in typical (albeit not ideal) conditions, then why doesn't
- Intel design the package with a built-in heatsink? Even if the CPU
- really does run OK without a heatsink or fan in a correctly-designed
- box, it is so predictable that many boxes will not be thusly designed
- that you would think it would be in Intel's interest to do this, to
- avoid the stigma of a flaky or under-designed chip.

- Comments, Intel?
