AGX thermal design guide question

On page 14 of the design guide, specifically section 3.1.2 figure 3-2, I’m trying to understand where the mating connector (on the back side) is in relation to this 75mm x 73mm key contact area. I’m designing a heat pipe cooler for an application in a very tight space, and for a few reasons, it would help if the flat pipe was only as long as necessary. I understand that best practice is to cover the entire plate, but because that may not possible, I simply need to know a reference feature for the key contact area. Thanks!

Hi, we don’t have suggestion than that in TDG. As said in the doc, “Full contact with the entire top surface of the TTP is suggested for maximum cooling”.
