Processor at 98 degrees centigrade, but no crash?

When my PC booted up a few days later it said
Check System Health ! VCore = 1.525
So I did, and looked at the PC Health Status thingy in me BIOS, and the Processor was running at 98 degrees centigrade! WTF? I'd been playing games and stuff for nearly a week, with no crashes!
It turned out I'd unplugged the CPU fan on my M/B by mistake

Jesus I was lucky!
