There is no
One Size That Fits All when it comes to overclocking. Your chip may not need as much voltage as a certain guide suggests. The required voltage is greatly dependent on what general computer enthusiasts refer to as the
Silicone Lottery i.e. some chips will be better overclockers than others.
You can by all means look at an overclocking guide, but it's generally advisable to increase the voltage in very small steps (e.g. 0.005) and test after each increase. To test, I use a combination of benchmarking software, including, but not limited to
Intel Burn Test,
OCCT and even
Folding@Home. You don't have to use all of them, but I've found some inconsistencies with reported stability when using just a single benchmarking test.
Your temperature issue may be down to how you applied the thermal paste, how the cooler has been mounted or you simply using too high of a voltage. Each
CPU has a limit in terms of how much voltage you can push through it and you might be at the point where you are pushing its limits. The
AUTO voltage setting usually uses a higher than required voltage, which is why it is not normally recommended to keep the voltage setting on normal, if you're worried about getting the best temperatures.
You should remove the cooler, clean the thermal paste, apply a fresh batch and then re-mount the cooler. When you install the cooler, tighten the screws in a cross pattern (
top-left screw and then the
bottom-right screw). This will ensure that even pressure is applied and will allow the thermal paste to spread evenly.
When you apply thermal paste, less is more. The contact between the
CPU and the
Cooler Heatsink only needs a very thin layer of thermal paste in order to transfer the heat efficiently. I usually use a small pea/grain of rice sized blob. In your case the contact between the cooler and your CPU may contain air-bubbles or the thermal paste may be too excessive, which is causing the massive spike in temperature. Whenever you remove the
Heatsink, you should always apply a fresh layer of thermal paste.
It's a lengthy process, but its all about trial and error. If you're still not happy with the temperatures after doing the above, you could try setting a custom fan profile using
Third-Party Software or through the
