Dell M6800 Maxwell GPU Heatsink...
Up for sale are a few Dell Heatsinks I managed to secure from a contact. These are the rare versions that allow fixation to the Maxwell GTX 980m and 970m (and probably others) without modification (no dremel required).
THERE ARE ADDITIONAL SOFTWARE STEPS to make these GPU's work in our Dell notebooks.
I will include the link with the instructions to the forum page with purchase (not sure if I can link to another forum here).
The upper copper piece is all in one plane, so that the height difference (with the added module from Maxwell) is no longer an issue.
Below is the link where these were once available a couple years ago.
