In this review, PC case fans from established manufacturers are subjected to various tests and evaluated based on the results.

\[ \begin{aligned} KL(\hat{y} || y) &= \sum_{c=1}^{M}\hat{y}_c \log{\frac{\hat{y}_c}{y_c}} \\ JS(\hat{y} || y) &= \frac{1}{2}(KL(y||\frac{y+\hat{y}}{2}) + KL(\hat{y}||\frac{y+\hat{y}}{2})) \end{aligned} \]

This is an inline \(a^*=x-b^*\) equation.

These are block equations:

\[a^*=x-b^*\]\[ a^*=x-b^* \]\[ a^*=x-b^* \]

These are also block equations:

$$a^*=x-b^*$$$$ a^*=x-b^* $$$$ a^*=x-b^* $$
