Pears0,
Back side of the back block... meaning there are two blocks. The front block (for the front of the video card) has the #Rotor area. The back block (for the back of the video card) has a simple clear path with a pad for contact on the BACK SIDE of the GPU.
So the pattern I posted is for the FRONT of the FRONT BLOCK (faces away from the front of the video card)
and this pattern is the BACK of the BACK BLOCK (faces the back of the video card).
Hope that somewhat clarifies it... :shrug:
