Even CPUs of today run above 100 degrees easily. Even 40 celsius is above 100 degrees. Which to human skin would hurt a lot. So yeah, that is quite normal, CPUs are hot when they get used. If i were to touch my Pentium 3 after playing 1 minute of Quake it would be hot.

Put simply, yeah its ok.

If that's the case then no biggie. Thanks for your reply!. After all these years this is the first time that has happened to me. Follow up question, so I guess these old CPU's weren't engineered/designed (or had in mind) to have heatsinks?

Back then people didn't care if these got hot so long they were stable, personally I would just slap a stick on heatsink and forget.

Yeah they werent designed for heatsinks. But like he said, just buy a heatsink if you want. You could still put one on. You wont need a fan for a 286.
