I recently had my cpu fan fail, I woke up to a bios message indicating CPU fan error, and of course when I check it, it was just kinda twitching around. I'm not sure how long the computer was powered up with that error message, but I suspect it was around 5-6 hours. Windows was running beforehand. But since replacing the fan I've noticed the performance has dropped a little bit and the system isn't as stable as it used to be, but its not consistent. I have small issues such as short and random freezing for a couple seconds, and the computer doesn't wake from sleep mode. These didn't start happening until after the cpu fan failure and I was wondering how likely is it that there is some cpu damage?
