I personally dock my laptop open, with some method of providing additional space below for added airflow. At home, that’s a 3D printed stand I modified to keep the monitor height even with the bottom of my second monitor (~6 in of air below the laptop). When traveling, it’s whatever I can stick under the back “foot” of the laptop (~0.5in of air).
