replace fan?

Hi, we’d like to replace the Nvidia TK1 CPU fan with an adequately large heatsink to reduce maintenance and pass mil-spec shock tests. Any info on the current fan’s footprint/style and any available heatsink alternatives would be most welcome. Thank you.
Best,
Pete

You can refer to this topic https://devtalk.nvidia.com/default/topic/926004/tegra-k1-dev-boards-cpu-fan/, just note, the heatsink choosing needs to follow thermal design guide.
