Guide: DFI NF4 Ultra-D to SLI-D modhardnrg -
Reaching The Contact PointNote: If you can't figure out how to remove the chipset fan, just give up now and buy an SLI-D/SLI-DR. This is also a perfect opportunity to switch out the stock DFI chipset fan for the much better Evercool VC-RE chipset fan!
This is the thing that most people are probably talking about when they say it's not possible on newer boards, it's just a covering over two points that you need to connect.
I just used a craft knife to scratch over the epoxy in all directions, being careful to not hit the nearby surface mounted component (I guess a resistor)
...and after some more scratching and a little clean up with IPA (using cotton buds / q-tips), you can see the exposed contacts!
