Video entitled "How to Install Thermal Pad Mod on EVGA GTX 1080 & 1070" on Gamers Nexus channel.
Just wondering what anyone makes of these comments made by someone named 'acnfanmanin':
"THATS NOT WHERE YOU PUT THE FRONT THERMAL PAD. You should put it on the HOTTEST part which is ON the baseplate itself. Those things you put on top of are CHOKES which doesnt get hot and dont mind being hot. You want the baseplate to be cold so it can cool the mosfets."
"No you're not supposed to put it on top of the chokes is what I'm saying. those things don't need cooling (look at motherboards and watercooling blocks they're never cooled) so you're wasting thermal pad contact area putting it there. You're better off putting it on the baseplate area on the right of the chokes because the mosfets which do get VERY hot are located under there connected to the baseplate."
"if EVGA told them to put it on the chokes...wt*...you're basically trying to cool a piece of copper...why"
He's actually correct. Majority of the heat is produced via the mosfets (not what everyone is calling the VRM). So without any testing that would be the most logical place to put the thermal pad. Chokes/Inductors don't really get hot at all and I would have thought covering them as EVGA advises would create a small pocket of air which would then be heated by the mosfets and unable to escape.
In saying that I think EVGA have just gone with a wider pad and the attitude "it all gets hot around that area so just cover 90% of it" whilst using the chokes/inductors as heatsinks.
With a different GPU as an example, according to this photo, the VRM is the entire section of this GPU,

whereas the mosfets are displayed as,

So regardless of whether people are calling the mosfets mosfets or vrm is unimportant as they still understand which of the underlying components are creating the thermal issue. As most are just mistaking mosfets as VRM's (when they are just a portion of the area) though they still understand the component in question and its location.
And while the user may be correct in placement above the midplate for the mosfets, the width of the pad like you said is covering that section in EVGA's pads correct? If so, then I don't understand why the user commented to begin with other than to maybe say the pad is wider than necessary which functionally is irrelevant?
