Blaxtreme

Hi, I purchased the Pacific V-RTX 2080Ti Plus for the Asus Strix and I have a question. After installing the block following the online instructions I noticed on some videos on YouTube that people are applying additional Thermal Pads to the areas highlighted in the pictures (I think VRMs) Please advise if I should dismantle and install thermal pads in those locations or not. Also are any thermal pads required on the back? My last question is it possible to retain the Asus back plate or do I have to install the TT one? Thanks.
