Hi guys
i have an msi GTX 1660ti armor and got some extra thermal pads that i don't use, so i would like to add them in the backplate to optimize temperatures. At the moment I put them rear the chip die (like forming a square) and RAM, but I'm afraid I have done something wrong, pads fit good and touch well the backplate, I would like advice on positioning, like a draw would be nice, thanks in advance

This is the gaming X but should be the same.

Anyway, usually "Metal" backplates have a protective plastic cover, to actually make good contact and transfer heat, you should cut that cover with something then putting the pad on top.

Agreed on removing the plastic film.

However, there are a couple of pad placement changes/additions I'd recommend. I don't believe the top row of GDDR is installed on this PCB, so putting a pad there is redundant. However, core and memory VRM cooling could be helped.
