Hi.
I've heard Pentium I and pentium pro do not have a thermal sensor, but PIII and later have, it can hang the system to protect overheating. What about Pentium II and PII Celeron? I cannot find their info anywhere... Also it's different between internal/external sensor, internal sensor can act reliably and quickly, external sensor is actually on mobo and some even don't work. So what type are in PII/III if it have one?
Thank you!

Thank you,
But I think you're not quite right, even the Pentium I have to use a heatsink...
I just want to know what will happen to PII if fan fails or even heatsink dropped, will the CPU damage? Or just hang the system?
 
Hi

I am sure i saw some old toms hardware videos of various old intel and amd cpu's where the heatsink was removed while system was running

Most amd cpus burned (sometimes also the motherboard destroyed)

Most intel cpus powered down then up again latter without damage

I will look them up latter (currently using a ipad mini)

Thank you, I already saw that, but the oldest CPU in that video is PIII, which hang without burn, but no PII test.
