Yes I was mistaken. I meant 1.072V for the CPU
Then you are fine as far as voltage is concerned. Look for the problem elsewhere. Start by re-seating the CPU/heatsink using Arctic Silver 5 or better. Check using RealTemp.
The Hyper 212 plus is a good heatsink for this purpose. I have the Hyper 212 EVO on my i7 3770K OCed to 4.5 GHz, and the temps hover around 42 degs. C
Also, please follow rds1220's recommendations and do a good cleanout of the computer.
