I need reassurance.

Earlier this day, I undervolted my CPU. I was pretty sure that it's stable since Prime95 didn't show any errors and everything passed, CPU is maxed at 75°c. Now, the thing is, when I stopped prime95, the moment I clicked stopped at Prime95, I heard the fan stopped spinning then I just felt something so hot in my laptop for a few seconds, let's say around five seconds. Then the BSOD showed. I just restarted the Laptop, then it showed me a message to go to BIOS, I just skipped BIOS and just clicked discard w/o saving anything. Then my Laptop started without errors. So, is there something that I did wrong? Or maybe it was just because of the heat when the fan stopped spinning? In case you want to know, I'm running on AC at that time, it was 28°c here when I started running Prime95.

The fan stop spinning thing could have something to do with the fancurve on the laptop. Some manufactures set the fancurve to respond to how much load is on the system. IMO that's a stupid way to cool a PC noise-wise. 

The BSOD could be a result of too much undervolting. Try running CPU stress test for 6 hours to really be sure that it's stable.

Now I see the reason why the fan immediately stopped spinning when the CPU load went down (after I stopped), I was shocked when I saw the temps spiked at 100°c above. I'm monitoring my temps at that time so I know the exact numbers. I will try running Prime95 again after a little bit more of research but I always see from other threads and posts that there are times that BSOD shows if a single component exceeded the max temp limit. If that's the case, I think my hunch is right, nevermind me I'm just guessing. Anyways, for some reason I have a doubt about it having too much undervolt since it can run games and applications alright. If your case is right about the fancurve of the fan, I think it is somehow right, because everytime I stop any stress test and the load gets down to the minimum, the fan stops immediately. I guess the fan spins depending on load, not on temps.
