The core voltage you're using is very safe.

 

I don't want to open a can of worms, but with Prime95, try to avoid thinking in terms of time. You see, the last time that I checked, Prime95's Blend test has 82 FFTs that it can go through, and it takes a lot longer than 12 hours to go through all of them; it can take roughly 24 hours, depending on your system.

 

Another thing that you can consider doing is selecting the Custom test. This will allow you to customize whatever test is currently selected. So, if you have the Blend test selected and you choose Custom, then you'll be able to customize the Blend test. This is good because then you can do the Blend test with a lot more memory used than just the default 1600 MB. It's usually best to use about 90% of your memory during a stress test, so with 8 GB of memory that comes out to be about 7373 MB. You can round it up or down too, it doesn't have to be exact. Remember one thing: if you do this, then pay attention to the CPU usage in Task Manager. You want it to be 100%, no less. You see, if you choose an amount of memory that's too high, then for some reason the CPU usage goes down and the test becomes useless. So you have the ability here to find the absolute maximum amount of memory to type in before you see the CPU usage dip below 100%, if you really wanted to.

 

Doing the Custom Blend test with about 90% of your memory used is far "better" than just the default Blend test, so I do recommend trying it!

What Vcore voltage would be considered as dangerous then ? What about the temperatures ?

For 24/7 use, I think it's best to stay under 1.4V, especially if your computer is going to be at 100% load frequently. For a quick bench run or for a CPU-Z validation, you can go a lot higher than that, even over 1.5V.

 

Temps: I think it would be best to stay below 90, but exceeding 90 isn't dangerous unless it's your average full-load temp. Then it can degrade the CPU just like with the voltage.
