Review on Geekworm Raspberry Compatible Expansion Extension by Johnny Santana

Like other reviewers, they noted that the bottom of the heatsink, which sits over the USB-C and HDMI ports, makes contact with those components before the heatsink support legs meet the circuit board come into contact. .020" heatsink in the area of the USB-C and HDMI ports, but it was still not enough that the heatsink's support legs made contact with the board, causing the board to warp slightly in that area. To solve this problem , make a 0.050" indentation on the bottom of the heatsink where the USB-C and HDMI ports are located. Otherwise, the heatsink does the job it was designed to do.
