Good aerodynamics. Heatsinks 70-284 must be designed in a way that air can easily and quickly float through the cooler, and reach all cooling fins. Especially heatsinks having a very large amount of fine fins, with small distances between the fins may not allow good air flow. A compromise between high surface (many fins with small gaps between them) and good aerodynamics must be found. This also depends on the fan the heatsink is used with: A powerful fan 70-291 can force air even through a heatsink with lots of fine fins with only small gaps for air flow - whereas on a passive heatsink, there should be fewer cooling fins with more space between them. Therefore, simply adding a fan to a large heatsink designed for fanless usage doesn’t necessarily result in a good cooler.
Good thermal transfer within the heatsink. Large cooling fins are pointless if the heat can’t reach them, so the heatsink must 70-293 be designed to allow good thermal transfer from the heat source to the fins. Thicker fins have better thermal conductivity;
