>I'm curious to see what the performance of that heatsink would be with a suitably-sized squirrel cage fan inserted into it. Surprisingly poor. A large conventional heatsink like the Noctua NH-D15 has far greater surface area. The densely packed fins of a conventional heatsink perform poorly if you're relying on convection, but they will dissipate a lot of heat with even modest airflow.
