Voltage issue with the i7 3770K

Specs: Windows 10
upgraded my cpu from i3 2100 to a used i7 3370k installed it on h61-s2p mobo then tried to stress the cpu but my temps got really high hovering around 85-90 underload and 45-50 on idle these temps with stock cooler so im getting the 212 evo then check the cpu voltages with programs like hwmonitor, cpuz, occt and speecy and they were all reading 2.448 V turned off the pc checked the voltages in bios and it was 1.524 V @ 3.8 Ghz disabled turbo boost and downclocked it to 3.3 Ghz check the voltages again and it was 1.412 so my question is what is causing this voltages to go that high i'm using HEC 650W been using it for over 2 years, is the cpu corrupted? the psu is failing or the motherboard is not compatible enough with the cpu the mobo is flashed to latest version , tried clearing cmos but nothing seems to work.

If the CPU temp is really that high & not just a software glitch, it means the CPU cooler wasn't installed correctly. Probably the thermal paste was applied wrong. Here's how it should be done: http://forum.corsair.com/v2/attachm...

As for the voltage readings, trust the BIOS over software. Also, check which BIOS version you have & then check the Gigabyte website to see if there's an update.

i'm using the stock cooler that i was using for the i3 2100 and i guess that what makes the temp go way over the limit.. and the thermal paste is applied correctly its not the first time i do something like this, as for the mobo voltage 1.524 v is pretty high for a turbo boost like 3.9 Ghz it should be around 1.15-1.20 v i guess so i don't what is causing this failure.

it would fry instantly above 1.85~ish volt, so its an incorrect reading

look at this for example:

i5-6600K[delid]@4.8GHz/4.3GHz@1.4v LLC=6 | 2x4GB Crucial-DDR4-2133CL15@14-14-14-28 1T 2700MHz@1.35v
MSI Armor RX 570 4GB@1340Mhz core@1.110v/1865MHz BiosModded

some folks said that my mobo sensor is off so i guess i shouldn't be worried , in hwmonitor the vid is normal 0.9V in idle and 1.15V underload so i the voltage per core is normal but the voltage in total is messed up.

I assume you mean the Core i3770K CPU (no 3370K mention anywhere).
Your motherboard lists the CPU with the F3 BIOS as being supported.
Intel recommends the Z77 chipset though for your newer CPU to get the best out of it (even sticking with stock speeds) and that is what I recommend. A Z68 series with the latest BIOS would be better than what you have though.
Your older stock heat sink has an aluminum core and the newer CPU would if using a stock heat sink need a copper core (like the non-K series comes with) but the 212 evo would be a better choice even without overclocking.

You have to be a little bit crazy to keep you from going insane.
