g'day and welcome to the forums. 
does the Y720 use thermal paste?
according to the hardware maintenance manual, it comes with paste rather than pads (page 47).
do you want to change from paste to pads for cooling the processor?

they grey stuff is thermal paste and that's the stuff you can clean and replace.
the 'whiteish' stuff look like thermal pads and are fine to leave as is.
if you are replacing the paste, get the good stuff, it's not much more than the cheap stuff and will give better heat transfer.
the bottom heatsink shown has the correct amount, just a blob in the middle, or smear a very thin layer all over the copper heatsink.
the one shown in the pic at the top used way to much and it has flowed over everything. not sure how much is over the other hardware that those two parts sit on!

the sheets of thermal gap pads come in many thicknesses.
get one of the pads that have been taken off and measure the part that hasn't been compressed.
from the pic, I'm guessing maybe 1.5mm - 2mm you'll be after.
or measure the compressed bit and double it would be a good indicator.

let's see if others have any thoughts.

why was this removed in the first place?
the pads are there as spacers between the boards and the heat sink to prevent wobble and possible short circuits.

I would not take too much notice of face book.
if all your pads measure the same height, then replace with the same thickness.
The only other way is to run something like a rule across the cpu to the chip and measure the height difference between each chip.
Where are you now on this and have you tried the information that was posted on your other threads that you have posted on?
