Thermal Paste Application Methods - Which one is best? - The Workshop

The Workshop presents a hands on comparison of several thermal paste application methods to determine which yields the best CPU temperatures. The host begins by outlining the methods to be tested: the classic pea dot (P) method, a simple line, an X pattern, a spiral, and variations involving spreading through different techniques including using a plastic bag to smooth the paste. Each method is evaluated under similar conditions using an ambient room temperature reading and a CPU stability test to track how the paste application affects thermal performance. Early in the test, the dot method is applied and the system is allowed to reach a steady state, with ambient temperatures around 16 to 17 degrees Celsius and CPU readings hovering around the mid to high 40s Celsius when IDA64 runs at load. The host observes that several of the traditional, visually distinct application styles produce nearly identical CPU temperatures in the same environment, suggesting that the exact pattern may be less critical than ensuring even coverage without excess or deficiency. The second method tested is the line, which is purposefully kept thin to avoid overhangs while covering the necessary contact area under the IHS. The host notes the line effectively mirrors the circle created by the dot method due to pressure dynamics, and the observed CPU and ambient temperatures remain essentially the same as the dot method, reinforcing the idea that surface coverage consistency is more important than the exact geometric shape. Moving on to the X pattern, the host admits unfamiliarity with the technique and proceeds with caution, again reporting temperatures that align with the prior methods, indicating that the X approach does not yield a noticeably different thermal result in this setup. A spiral application is then attempted, described as awkward, with results similar to the other methods, further supporting the trend that the method choice has minimal impact on performance under these test conditions. After exploring several standard techniques, the host experiments with extremes by testing too little and too much paste. The too little scenario produces a noticeably higher CPU temperature, while the too much scenario also fails to significantly exceed the higher end of prior results due to excessive paste not necessarily translating into better cooling. The overall takeaway from these tests is that while excessive paste around the edges should be avoided and conductivity considerations matter, the practical range of common methods yields comparable thermal outcomes. In conclusion, the simplest approach, such as the line or pea method, is recommended for its ease and reliability, with the note that the exact method is less critical than achieving even, adequate coverage without shorting or spreading paste beyond the CPU die.
