I am asking for help, what thickness are the thermal pads in the lenovo legion y720 laptop?

[Bruce]

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 problem is that the thermal pads “white” have unfortunately already been removed at the instigation of a friend and I am looking for information about the thickness of these thermal pads

[Bruce]

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.

[Kostka]

from the information I got. 1mm and 1.5mm were used. but I can’t tell where it is 1.5mm and where it is 1mm. I’ve tried it a couple of times and I don’t see any difference

[Bruce]

let’s see if others have any thoughts.

Since yo have removed the pads can you post a new pic.
Do you still have all the old pads?

[Kostka]

yes i have all old pads. Should I take a photo from above or from the side?

So if you measure the bumps (non compressed parts) do you get 2 different sizes?

[Kostka]

I don’t see the difference, it should be

[PeterOz]

Not really
Where did you get the 1 and 1.5 from?
