vulcanraven,
Something definitely doesn't add up.
AI suite is not the way to read your processor temperatures. I suspect that it's wrong by 30C! AI Suite is reading CPU temperature,
not Core temperature. Use Core Temp or Real Temp to read your Core temperatures.
Also, 16C-25C (60.8F-77.0F)is a
very wide window. What exactly is your ambient temperature?
1.35 Vcore is way too high. On mid-level air like your 212 EVO, 1.35 should instantly peg your Core temperatures at 100C causing your processor to throttle! Have you observed "Core Speed" in CPU-Z during Prime95 Small FFT's?
Also, I question your test methods. Which version of Prime95 ... and which torture test?
There's a proper way to test your rig. Please thoroughly read this Tom's Sticky:
Intel Temperature Guide -

From the Guide:
" ...
Section 1 - Introduction
Whether you overclock or not, the topic of processor temperatures can be very confusing. Intel desktop processors have thermal sensors for each Core, plus a sensor for the entire processor, so a Dual Core has 3 sensors. Heat originates within the Cores where Digital sensors measure Core temperatures. A single Analog sensor under the Cores measures overall CPU temperature.
Core temperature is 5C higher than CPU temperature due to sensor location. The relationship between Core temperature and CPU temperature is shown in engineering documents. The Thermal Specification is "Tcase", which is CPU temperature. Tcase for the i5 4690K is 72C. Tcase + 5 makes the Core temperature 77C. ...
Section 2 - Ambient Temperature
Also called "room" temperature, this is the temperature measured at your computer's air intake.
Standard Ambient temperature is 22C. This is a very critical measurement, because
Ambient directly affects all computer temperatures. Use a trusted analog, digital or IR thermometer to measure Ambient temperature.
Here's the temperature conversions and a short scale:
Cx9/5+32=F ... or ... F-32/9x5=C ... or more simply ... an increase of 1C = an increase of 1.8F
30.0C = 86.0F
Hot
29.0C = 84.2F
28.0C = 82.4F
27.0C = 80.6F
26.0C = 78.8F
Warm
25.0C = 77.0F
24.0C = 75.2F
23.0C = 73.4F
22.0C = 71.6F
Standard ... or ... 22.2C = 72.0F
21.0C = 69.8F
20.0C = 68.0F
Cool
As Ambient temperature increases, thermal headroom and overclocking potential decreases.
Section 3 - CPU Temperature
Also called "Tcase", this is the temperature shown in Intel's Thermal Specification - http://ark.intel.com/ It's measured on the surface of the Integrated Heat Spreader (IHS) under tightly controlled laboratory conditions at 22C Standard Ambient. For lab testing
only, a groove is cut into the surface of the IHS where a "thermocouple" which measures temperatures, is embedded at the center. The stock cooler is seated and a steady-state 100% workload is applied. Peak temperature is reached within 10 minutes.
Since there's no thermocouple on any processors outside Intel's labs, a single Analog Thermal Diode located in the center under the Cores is used to substitute for a thermocouple. This sensor measures "CPU" temperature, which is the overall temperature of the entire processor. The Analog value is converted to Digital (A to D) by the Super I/O (Input / Output) chip on the motherboard, then is calibrated to look-up tables coded into BIOS for each socket-compatible processor.
CPU temperature in BIOS is higher than in Windows at idle, because BIOS starts the processor at boot voltage to ensure that it can initialize under any conditions. The monitoring utilities provided by motherboard manufacturers on your Driver DVD reads CPU temperature. Thermal code can vary greatly between BIOS suppliers and version updates, and can be wrong by up to 30C.
BIOS or CPU temperature may not be accurate.
Section 8 - Overclocking and Vcore
Overclocked processors can reach up to 150% of their Thermal Design Power (TDP) when using manual Core voltage (Vcore) settings, so
high-end air or liquid cooling is critical. Every processor is unique in it's overclocking potential, voltage tolerance and thermal behavior.
Regardless,
excessive Vcore and temperatures will result in accelerated "Electromigration" -
https://www.google.com/?gws_rd=ssl#q=Electromigration - which prematurely erodes the traces and junctions within the processor's layers and nano-circuits. This will eventually result in blue-screen crashes, which will become increasingly frequent over time.
CPU's become more susceptible to Electromigration with each Die-shrink, so 22 Nanometer architecture is less tolerant of over-volting. Nevertheless, Vcore settings should not exceed the following:
-> Core 2
1st. Generation 65 Nanometer ... 1.50 Vcore
2nd Generation 45 Nanometer ... 1.40 Vcore
-> Core i
1st. Generation 45 Nanometer ... 1.40 Vcore
2nd Generation 32 Nanometer ... 1.35 Vcore
3rd Generation 22 Nanometer ... 1.30 Vcore
4th Generation 22 Nanometer ... 1.30 Vcore
When tweaking your processor near it's highest overclock, keep in mind that for an increase of 100 MHz, a corresponding increase of approximately 40 to 50 millivolts (0.040 to 0.050) is required. ... "
