Even though I have listed all of the temperatures of each one of the cores of the Intel Core i7 3820 CPU, I will be taking the average of each one of the tested thermal paste/compounds, this is achieved by adding each one of the individual cores of that specific thermal paste/compound then dividing that by four.
Now looking at the average CPU temperatures from all of the tested thermal paste/compounds, the Gelid GC-Extreme gave us the best average CPU temperature of 28°C; which, I will use as my base line CPU temperature. Being, followed by the Antec Formula 7 compound which comes in at 29.25°C which is a 1.25°C increase. With the PK3 thermal paste/compound it comes in third place with an average CPU temperature of 30.25°C which is an increase of 2.25°C when we compare it to the GC Extreme. And finally, the PK2 thermal paste/compound average CPU temperature of 31.25°C which is an increase of 3.25°C when comparing it to the GC Extreme, putting this compound in last place.
While knowing what the CPU idle temperature is, and important to know, it is not a true test of how our thermal paste/compounds perform. It is the full load testing of the CPU that will make or break our cooling efficiency of our computers. So let’s move on to the full load testing results and see how the Prolimatech’s PK2 and PK3 thermal paste/compounds compare.
Let’s get the average of all of the tested thermal paste/compounds and see how things compare then. Like what I did during the idle load testing, I will be using the Gelid GC Extreme as my base line CPU temperature. The average temperature of the GC Extreme is 65.5°C. Averaging up the CPU temperatures of the Antec Formula 7 we get 65.25°C which is a decrease of 0.25°C when we compare it to the GC Extreme temperature. When we compare the PK3 average CPU temperature of 68°C to the GC Extreme average temperature of 65.5 we get an increase of 2.5°C. And finally looking at the average CPU temperature of the PK2 thermal paste/compound we have 69.25°C which is an increase of 3.75°C when compared to the average CPU temperature of 65.5 with the GC Extreme.
