Nvidia ConnectX-6 User Manual page 44

The thermal pad should be applied on the coldplate from its tacky (wet) side. The pad should
be applied with its non-tacky side facing up.
2. Ensure the thermal pad is in place and intact.
3. Once the thermal pad is applied to the ASIC interposer, the non-tacky side should be visible
on the card's faceplate.
4. Gently peel the liner of the pad's non-tacky side visible on the card's faceplate. Failure to do
so may degrade the thermal performance of the product.
Install the adapter into the riser and attach the card to the PCIe x16 slot.
