I was not able to find the actual dimensions of the PTM7958 thermal pads on Framework’s website. The only information is here and is specific to fitting Framework computers.
But what about non-Framework devices?
I bought two sizes and documented the dimensions for posterity. If someone wants to add in the dimensions of the other sizes, that would be great. Although it would be better if Framework would document it. Hopefully this will be useful to someone!
Size A: 20mm x 25mm
Size C: 13mm x 21mm
