When applying thermal paste, what is a common mistake to avoid?

In the context of applying thermal paste, it is important to recognize that both applying too little paste and applying an excessive amount can lead to inadequate heat transfer between the CPU and the heatsink.

When too little thermal paste is used, it may not cover the entire surface area of the CPU, which creates air gaps. These gaps can trap heat and prevent efficient heat dissipation, potentially resulting in higher temperatures and reduced performance or lifespan of the CPU.

Conversely, applying an excessive amount of paste can also be detrimental. Excessive paste can ooze out from the sides when the heatsink is placed on top, leading to potential electrical short circuits or contamination of surrounding components. Additionally, too much paste can actually hinder heat transfer rather than enhance it, as it may not provide better coverage compared to a thin, even layer.

Thus, avoiding both the application of too little paste and too much paste is crucial for optimal thermal performance and component longevity, making the answer comprehensive in capturing the key mistakes to avoid when applying thermal paste.
