Thermal Paste Roundup 2015 – 47 products tested with air-cooling and liquid nitrogen (LN2)
Thermal Paste Test Requirements and Basics
Following the test from 2013 a lot of thermal pastes are very close together taking a look at the performance. Differences of only 0.1 °C are very common and this is also the interesting and challenging point of thermal paste reviews.
A lot of websites just use CoreTemp and measure the differences in the CPU core temperature. The issue is that a temperature change of 1 °C, which is the smallest step, is already crashing the whole test. Also a varying room temperature of only 0.5 °C can easily ruin your results.
In the past I always measure the delta temperature between the CPU-Heatspreader and the base of the CPU-Cooler using K-Type thermal probes. However these temperature probes are quite inaccurate with sometimes up to 1 °C temperature differences depending on the quality of your probe and the thermometer.
Measuring the delta temperature eliminates the measuring errors of the changing room temperature. However the K-Type probes are still not accurate.
