\section{Optimization}
\par The heatsink is first taken into consideration and the number of fins on it are optimized in the range of 8 to 20. Fig \ref{fig:all_count_graph} shows a plot between the number of fins and the overall temperature of the hottest components. After running the optimization study it is found that a fin count of 16 is the most efficient at keeping the temperatures lower than the other fin count configuration.

\pagebreak \par The second variable that was chosen to alter was the location of the fans itself. But no improvement was noticed in altering the fan location. The angle of the fans was also considered but it led to very high temperatures on the Bridge so that variable had to be abandoned.
\par After much research and consideration wedges were chosen to allow the air flow to stabilize and reduce the amount of vortexes that were being generated. A variety of wedge shapes were taken into consideration while running the simulations.
\subsection{1st Case}
\par For the first design, a split triangular wedge is chosen for the space in between the fans and half wedges were chosen for the corners. This reduced the extent of vortex formation to some extent but ended up increasing the temperature overall. The design of the wedges require further refinement.

% 2 STEP WEDGE DESIGN ON THE OUTER EDGE
\subsection{2nd Case}
\par It was observed that the air flow was getting trapped inside the gap between the wedges in the first case, so the gap was eliminated by replacing the 2 split wedges with a single broad wedge and the corner wedges were also altered in geometry. This geometry did prevent the air from getting trapped but ended up generating 2 smaller vortexes.

\par The side wedges were removed to prevent the air from suddenly expanding and causing the vortex to form. The middle wedge was also altered to have openings in the Z plane. The size of the vortex became smaller but the max temperature was increased in doing so.

\par By changing the geometry of the side wedges from case 2 the vortexes being formed in the corner are almost eliminated but the right fan is trapping the air flow generated by the left fan. This leads to again having a higher peak temperature.

\subsection{3 Fan Cases}
\par A common issue with 2 fan configurations was that the right was trapping the air from the left fan even when the vortexes were reduced significantly. A rather complicated solution for solving this issue was to use another fan in the middle. This comes with its own set of challenges but it did decrease the temperature while again having the vortexes near the fans even though them may be small.

\par To reduce the amount of the vortexes, prior solutions that were employed in the 2 fan configurations were adapted for the 3 fan configurations. The first case uses four 15mm long wedges that are 20mm in height. This allowed vortexes to form on top of the wedges because the wedges didn't span the entire height of the casing.
\par The wedges were made 5mm longer and lifted up to reduce the space above them. This did reduce the size of the vortexes but not enough for the project to be considered successful.
