A few days ago, I saw an advertisement claiming that skewed fin can increase heat dissipation by about 20% compared to straight fin. Today, I conducted a simulation to compare the two under identical external conditions of heat generation, power consumption, heat sink size and volume, and tooth spacing. Let's take a look at the analysis below.

 

Firstly, let's take a look at the results of the straight teeth, which had a power consumption of 9W.
