Stock Intel Core i7 3770K temperatures on full load

viniciusrodsilva,

If you don't plan to overclock, then the stock cooler is adequate for your i7 3770K.

What is your ambient temperature?

Mid-70's for Core temperatures are safe for everyday real-world workloads. 100% workload such as Prime95 version 26.6 Small FFT's will typically push your processor close to 80C, but BF4 is not close to a 100% workload, so your Core temperatures shouldn't be so high.

Core Temp is fairly accurate because it's measuring the digital Core sensors, but AI Suite II is measuring the single analog CPU sensor, which in this instance, is not accurate.

Here's why:

From this Tom’s Sticky (please read): Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

" ... Section 1 - Introduction

Intel desktop processors have thermal sensors for each Core, plus a sensor for the entire processor, so a Quad Core has five 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. Intel's Thermal Specification is "Tcase", which is CPU temperature, not Core Temperature. Tcase for the i7 3770K is 67C. Tcase + 5 makes the corresponding Core temperature 72C.

The relationship between Core temperature and CPU temperature is not in the Thermal Specifications; it's only found in a few engineering documents. ... "

Also called "Tcase", this is the temperature shown in Intel's Thermal Specification - http://ark.intel.com/ ...

... 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.

... 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. ... "

viniciusrodsilva,

I believe that your CPU temperatures are too low by as much as 15C, which comes as no surprise, so I recommend that you ignore AI Suite II. However, this is not your real problem, which is indicated by your Core temperatures.

If you've been running your rig for 2 years or so, it's possible that your thermal compound has dried out and needs to be replaced. Regardless, what is most likely, is that one of your cooler's push pins in at least one corner has popped loose. Have you moved your computer recently?

You can check the push pins by running a load while pressing down firmly on each corner of the cooler for about 30 seconds. If your Core temperatures drop significantly, then you've found the unseated push pin.
