In bios, the temperatures read about 40 degrees (extremely hot in the room). but in Hw monitor it reads about 50-55 degrees with vcore at 1.7! Is hwmonitor reading the voltage wrong, or is the BIOS in need of a reset?

Now that the room temperature is normal, Real temp is recording 30-35 degrees which seems normal. But I also notice that my cpu Cooler (CM 212 EVO, is not fully covering the surface of the CPU, tried to seat it that way, but because of how to screws are put into place, made it impossible :( Time to look for a new cooler perhaps? They currently have a sale on the Corsair Hydro series at the website I usually purchase my computer parts.

Another unusual thing I noticed when running a Prime95 torture test, is that it jumps right from 30-35 degrees, and then right up to 50-55 degrees. Perhaps I used a bit to much thermal past or the cooler is badly seated? The cpu temperature does not go above high 50s, but the temperature spike just after a few seconds to me seems odd when applying stress.

hmm, maybe I just used a bit much thermal paste, or the compound just need time to settle idk, I will definitely continue to monitor temps doh, because the temperature did not spike like this with my old Phenom II 955 3.7 ghz OC. at a max temp of 56 degrees with "turbo" enabled at 3.9ghz, doesn't it seem a bit high?

That's really, really low. Intel cpu's are not even considered hot when amd cpu's start melting. Generally anything under 65° under 24/7 is considered fine, anything under 85C is fine for stress testing.

You will have to wiggle that out yourself, as each chip has it's own characteristics. Might be somewhere between 1.15-1.3v for 4.4ghz. I'd start with 1.25v, if it's stable go down in like 0.01v steps until you are not stable anymore, then set it 0.01v higher again so you are stable. If you are not stable with 1.25v up the voltage in 0.01v steps until you are stable.
When you need less then 1.25v for 4.4ghz chances will be good that you can reach 4.5-4.6ghz. Usually 100mhz increases will only need a very tiny adjustment in voltage, once you need a lot more for a step of 100mhz I'd go back.
So for example if you need 1.25v for 4.4ghz but 1.32v for 4.5ghz, you should stay at 4.4ghz. If you can get 4.4ghz with 1.25v and 4.5ghz with 1.26v you can try to up until you need a lot of voltage increase for the next 100mhz. I'd personally stay below 1.3v, even if temperatures are fine.
