Due to the large number of requests and misinformation posted in various locations, we're going to add all the information about the pads and locations to put thermal pads, if you'd like to try this yourself.  This will not be a comprehensive walkthrough.  I'll probably add links to the various installation guides when I can make them available.  Remember, this is optional, and this post is only for people who want to purchase pads themselves.  If you are wary over getting the wrong pads, then simply go to our Thermal Mod page and request a Thermal Mod Kit, or request a RMA for EVGA to do this for you.
 
Again, if you don't have a card on the Thermal Mod list, do not attempt this.  There are many reasons for this, such as your card will not benefit from this (e.g. blower models), you have a different brand of card (can't imagine what could go wrong there...), or you could potentially damage a card not designed for this mod.
 
GTX 1060s are excluded from this list, since the Thermal Mod kit for these models includes a baseplate, which does not come stock with the GTX 1060, and would render your attempt to improve the 1060 futile. 
 
I will not post links to manufacturers of thermal pads, because we won't suggest brands to use.  Members may certainly suggest options in the comments, however.
 
Due to the similarity of PCB designs, there are only four real differences between these models, so I will list the models that apply to each, rather than sort by GTX 1080, GTX 1070, etc.  It's also important to note that different sets of cards may use a different thickness for the baseplate pads.  Please read carefully before purchasing any pads.  EVGA will not be responsible for your mistake in purchasing pads, considering EVGA is offering Themal Pad Mods free of charge.
 
DO NOT STACK PADS.  THIS CAN GREATLY DIMINISH COOLING PERFORMANCE.  If you cannot find pads long enough or wide enough, however, it's perfectly acceptable to simply place them next to each other end-to-end or side-by-side.  If you choose to purchase new pads, however, make sure all pads are the correct thickness first.
 
All of these cards now use different memory pads, or are modified with the Thermal Mod kit, so this information will apply to all models below:
 
Memory Thermal Pads:
1x Small, two memory chip pad:     15mm x 33mm x 1.5mm  +/- 0.1mm
2x Larger, three memory chip pad:  15mm x 50mm x 1.5mm  +/- 0.1mm
Here's a location guide for any of these baseplates.  You may also place the thermal pads directly on the memory instead, but you may find it easier using the baseplate:

 
Now, to card specific thermal pads:
 
GTX 1080 Classified
08G-P4-6386
08G-P4-6384
 
The Classified Mod requires the addition of four thermal pads.  At this time, I don't have an alternate suggestion for the pads.  All four pads are required.  Note that the Classified is the only card on this list that does not place a thermal pad between the baseplate and heatsink/fan.  However, the Classified is also the only card adding a larger thermal pad on the PCB side between the baseplate and PCB.
 
Baseplate pads:
1x  17mm x 95mm x 1.5mm +/- 0.1mm
1x  11mm x 32mm x 1.5mm +/- 0.1mm
Backplate pads:
1x  19mm x 95mm x 2mm +/- 0.1mm
1x  19mm x 55mm x 2mm +/- 0.1mm
 
For the Baseplate:  This is the PCB side of the baseplate facing you.  Note the circled pads.  The longer of the two pads requires you to remove the old, skinny thermal pad on the PCB before applying the new one.  Likewise, the shorter thermal pad should be placed on the narrow strip underneath the red thermal pad in the image:

 
For the Backplate:  For this image, ignore the blue sections as they aren't thermal pads; instead, it's simply the reflective sticker on the backplate.  The circled images are locations are rubber standoffs that need to be removed prior to adding the new thermal pads (i.e. the big red rectangle and smaller red rectangle):

 
Next up, the FTW cards.  We've found two different thermal pad configurations that work similarly, so I'll give you both the standard Thermal Mod kit sizes, and also the alternate choice in pads, which might be easier to locate:
 
GTX 1080 FTW and FTW DT:
08G-P4-6286
08G-P4-6284
GTX 1070 FTW and FTW DT:
08G-P4-6276
08G-P4-6274
 
As noted earlier, these cards share the same PCB, and thus share the same instructions.  Here are the pads:
 
Regular Thermal Mod Pads:
Baseplate (Narrow): 1x  26mm x 110mm x 1mm   +/- 0.1mm
Backplate (Wide):    1x  58mm x 110mm x 2mm   +/- 0.1mm
 
Regular Baseplate:

Regular Backplate (make sure to remove any rubber standoffs under the shaded section):

 
Alternate Thermal Mod Pads:
Alternate Baseplate (Really narrow): 1x  8.5mm x 110mm x 1mm +/- 0.1mm
Alternate Backplate (Narrower):
1x  19mm x 110mm x 2mm   +/- 0.1mm
1x  19mm x 55mm x 2mm     +/- 0.1mm
 
Alternate Baseplate Pad:

 
Alternate Backplate Pads (make sure to remove rubber standoffs in the same area you would for the regular Thermal Mod pad):

 
So, let me explain.  You may mix and match baseplate and backplate choices.  If you choose the alternate backplate, however, you must use both pads.  There will be no cooling performance difference, so long as you properly install the pads.
 
GTX 1080 and 1070 ACX 3.0 and ACX 3.0 SC cards:
 
GTX 1080 ACX 3.0 and ACX 3.0 SC:
08G-P4-6183 - EVGA GeForce GTX 1080 SC ACX 3.0 - Primary BIOS (86.04.3b.00.82)
08G-P4-6181 - EVGA GeForce GTX 1080 ACX 3.0 - Primary BIOS (86.04.3b.00.82)
GTX 1070 ACX 3.0 and ACX 3.0 SC:
08G-P4-6173 -  EVGA GeForce GTX 1070 SC ACX 3.0 - Primary BIOS (86.04.50.00.72)
08G-P4-6171 -  EVGA GeForce GTX 1070 ACX 3.0 - Primary BIOS (86.04.50.00.72)
 
Similar to the FTW cards, there is both a Regular Thermal Mod set of pads and an alternate.  However, the ACX 3.0 and ACX 3.0 SC only have a single backplate pad used as an alternate:
 
Regular Thermal Mod Pads:
Baseplate (Narrow):  26mm x 93.4mm x 1.5mm +/- 0.1mm
Backplate (Wide):     58mm x 93.4mm x 2mm +/- 0.1mm
 
Regular Baseplate:

Regular Backplate (remove any rubber standoffs underneath the shaded area):

 
Again, the alternates look slightly different, but maintain the same cooling performance.  Also, unlike the FTW cards, there is only a single backplate pad:
 
Alternate Thermal Mod Pads:
Alternate Baseplate (Really narrow): 1x   8.5mm x 93.4mm x 1.5mm  +/- 0.1mm
Alternate Backplate (Narrower):       1x   19mm x 93.4mm x 2mm      +/- 0.1mm
 
Alternate Baseplate (Review the FTW Alternate Baseplate picture above if you want to see exactly where this goes.  Same concept, just different size pad):

Alternate Backplate (remove any rubber standoffs located in the area shaded by the original backplate pad above):

 
Lastly, we get to the GTX 1070 Black Edition cards, which do not feature a backplate.  As such, there's only two options for baseplates.
 
GTX 1070 Black Edition and Black Edition SC:
08G-P4-5173
08G-P4-5171
 
Baseplate (Narrow):                          1x  26mm x 93.4mm x 1.5mm   +/- 0.1mm
Baseplate Alternate (Really narrow):   1x  8.5mm x 93.4mm x 1.5mm  +/- 0.1mm
 
Regular Baseplate Pad (yes, same as above for 1080 and 1070 ACX 3.0 and ACX 3.0 SC):

 
Alternate Baseplate Pad (yes, same as above for 1080 and 1070 ACX 3.0 and ACX 3.0 SC):

 
 
As noted above, this is not designed to be an installation guide, but a reference for those willing to do this themselves.  I'll keep an eye on the comments if something needs clarification.  Otherwise, this is a DIY project.
 
Edit:  I'll put the VBIOS links on this page, as well.  No new updates on that front, compared to Jacob's thread.  Just adding it for people who want to make sure they've done everything.  Incomplete as of 11/22.
 
Edit2: Re-added the images, as they seem to have disappeared.

    I asked Jacob, and he said the W/mK doesn't make much of a difference, so there's no recommendation on minimum W/mK.  
     
    Think of it like thermal paste.  You can purchase higher-end thermal paste, and it will lower the temperatures more, of course, but it's more important that the thermal paste is applied properly and the heatsink makes good contact.  In other words, whichever pads you purchase, just make sure they are the correct size and make contact.

    No minimum W/mK to recommend, generally.  As above, make sure you have the right-sized pads.  


    If you're adding an additional pad on top of the MOSFETs, I'd need to know which card you have.  Only the 1080 Classified is suggested to have a new pad replace the current one in that region.  Otherwise, I could only offer an educated guess.

    First of all thanks a lot for the information.
     
    For the VRAM
    Does it matter if I use a couple of rectangular pads covering 2 or more memory chips as shown above
    vs
    having 8 separate square pads (as it was originally shipped with)

    No. It's easier if you stick them directly onto the base plate in one rectangular piece. It's up to you.

    Thats strange. There are pads 1w/mk and 12w/mk. I think there is a difference. :) But nevermind.

    I have 1070 FTW 08G-P4-6276-KR and i want to replace original mosfet pad because it doesnt have contact with two mosfets for VRAM VRM. (they have a little bit less height than rest). I think that original pad is 1.5mm. If i use 2mm would that be ok?

    Given that the Classified uses a 1.5mm pad for the same area, I would still probably recommend 1.5mm.  As far as 2mm goes, it may make the baseplate a little harder to screw back down, but nothing inherently wrong with the idea.  However, after first screwing the baseplate back on, I'd suggest checking the three memory pads on the opposite side of the PWM area relative to the MOSFETS to make sure they're making good contact, since the memory pads should be 1.5mm thick.

    Some names of the high end stuff, can get very expensive.
     
    Some stores, use at your own risk
    I'm getting two high end thermal pads (7 to 11 W/mK) for the VRAM and VRM. And 5 W/mK ones for the wide and narrow pads.

    5 W/mK is probably what you get from EVGA. Wich is fine.
    I fear people see all these numbers and now they are worried that low is bad.
    I regularly apply alu or copper shims and sinks to chips. The silicon to "glue" it is only 1 W/mK lol.

    But 1.5mm still leaves these two mosfets with no contact. Ill try 2mm, it should compress enough to not interfere with VRAM pad.
    Thanks!

    I use 1070 FTW. I'm expecting a thermal pad to be in for 4 weeks. Sorry, but if you do not send in the near future, it will be filled with burned cards. What are you still waiting for? Let's open the RMA and return the card. We have been patient for over a month. Now hold your Evga hand quickly and start submissions.
     
    We will disassemble the cards and install them again.
     
     
    Thank you!

    As EVGA has repeatedly tried to point out... the fitting of these extra pads is "optional".
     
    Try reading this article that totally debunks the mass hysteria that appears to have arisen over this issue.
     
    http://www.gamersnexus.net/guides/2691-final-evga-vrm-thermal-torture-test-and-analysis
     
    A couple of quotes from the conclusion of the above article:

    How Many EVGA Cards Have Failed?

    "In speaking with EVGA, it sounds like they're at about a 200 DPPM (Defective Products Per Million) rate for their cards. This means that, for every one million cards shipped, about 200 are defects. We're told that this number is fairly consistent with previous generations, it's just that the defects are more noticeable this time because of the way the internet works."
     
    "It's clear to us, at this point, that there's no thermal issue with EVGA's cards. Any defects we're seeing are being caused by other factors, like workmanship or manufacturing defects."
     
    PS. Maybe worth pointing out, that the guy that wrote the above article (IE. Steve Burke of GamersNexus.net) is very well respected in his field. And totally independent.

    For the Baseplate:  This is the PCB side of the baseplate facing you.  Note the circled pads.  The longer of the two pads requires you to remove the old, skinny thermal pad on the PCB before applying the new one.  Likewise, the shorter thermal pad should be placed on the narrow strip underneath the red thermal pad in the image:


    I have reviewed a 1080 classified and bring new bios and all thermal pads installed except the shoorter thermal pad placed on the narrow strip..... Have yoy decided to modify the mod in the factory or is it a mistake and have forgotten to install it?
    What are the final and correct instructions to install the thermal pad in the 1080 classified?

    TomsHardware has a page about the EVGA GTX 1060 SC within this new Roundup :  
     
     Nvidia GeForce GTX 1060 Graphics Card Roundup.   March 21, 2017 .  by Igor Walossek
     
    The author talks about The Cooler and VRMs heating to 120C . INCLUDING INFRARED THERMAL IMAGES
    He suggests a simple mod : add thermal heat pass to  the "leg" of the HeatPipe just 2.5mm above the row of VRMs. 
     
    I am thinking of carving a Copper block instead of the Thermal Pads he used, which reduced VRMs Temp by ~8C ! . 
    A Copper heatsink would definitely be better
    Than I was wondering if I could create block/s for the memory chips ..
     
    •  Does the Stock card use any Thermal Pads - to worry about replacements ( location ? sizes ? )
    •  Would heating the Pipe at its heat expelling end hinder its performance with regard to the GPU ? I think it needs external Temperature difference. 
    •  What are the measurements of the Heatpipe pipe ? Width x Height , and maybe the Length for the VRMs row ?  
     
    I chose this thread as the original poster is an official man "in the know", though his answer would not be regarded official EVGA's.   
     
    Thanks in advance

    #1 The review was using the default fan curve shipped with the card. A higher fan curve will reduce temps significantly.
    #2 The VRM's actually reached 119.4C in the review. Good thing the VRM's are rated at 125C.

    Yeah , well , I did NOT try to say anything negative, and neither did he .
     
    btw "Our stress test gets them up to 246°F (119°C). Although that sounds bad, it's not out of spec for the built-in MOSFETs, which are rated at up to 302°F (150°C).
     
    But if I can easily improve , and I have been making and experimenting my own watercooling ever since OC started ( actualy with the Original TomHardware , the german doctor talking about jumpers from 66 to 100 ).  WHY NOT. I already checked and i do have 1mm x 16mm copper strip (leded though ) I can fold , thermal glue and sand to fit. 
     
    I need knowledgable info / advice  , and  is the best I know.  Its the basic engineering principles that i need here
