No (!) and no (!) and no(!) - never do this on modern hardware!

Not even for under an hour, just to install a different kernel? Does it permanently damage the hardware somehow, is that what you're saying?

I haven't found anything to substantiate this, just that OS-level power management is disabled. Firmware-level safeguards for processor temp, etc are still in effect, as far as I can tell. Though my CPU never got even above 60°C when installing 15.10

I ran my chromebox for an entire day with acpi=off and saw zero impact beyond one of my CPUs being disabled. That's a short time and a small sample size, though. And Fritsch certainly seems sure about it!
