I have tried to read as much as I can about OC'ing here and other sites. I have found that I completely understand parts of it, and others not so much....but with the reading I have done I have successfully and have stable OC higher than I have been able to achieve before. I read guides specific to my motherboard and CPU which was really helpful.

I was curious about one aspect.

If you OC and the voltage isn't high enough I know it can lead to instability, which I understand. If the voltage is too low does it also generate MORE heat, not less?

No, voltage too low would produce less heat.
This is what I thought, so riddle me this....

I am OC'ing on a R7 1700 ASRock Taichi X370 on a Cooler Master Hyper 212 Evo. Two intake fans, two exhaust fans. Using Prime95, CPU-Z, and Cinebench 15 to test.

If I set to anything above 3.5/1.2150 volts it will "act" ok until I run a stress test or more specifically run a certain game. The core temps run up past mid 70's and then shutdown. I had it set at 3.8/1.34 ran fine all winter and suddenly it would overhead and shut down. When "warm" out my ambient is 74F in the house.

Just for the heck of it I tried 3.9/1.4 and it benches perfectly, gets no hotter than 70C. Even in the certain game, the highest I saw was 67C which it was surpassing on the 3.5 OC.

Not really sure what's going on as I haven't gotten so deep into it as to change advanced settings in the BIOS.

In game it's usually a slight stutter then hang, game crashes return to desktop where it may or may not be hung. Sometimes black screen restart. When running a bench it is more often "your pc" blue screen restart.
