I did this and it work for me, increased my Tx Power without burning the chip

Does the WR-1043nd v3 have such a heatsink preinstalled? I could get 23 dBm on it even with the factory firmware(by setting country to US), and it doesn't get hot. The max txpower it supports is 24 dBm.

according to the Video opening 1043ND V2 there is no heatsink

double sided tape? for a heatsink? are you kiddin?

and it doesn't get hot

ahaha, sure, cuz tape succesfully shielding heatsink from a chip surface smile

after a few time your heatsink will come off due to glue thermal degradation and can short some board contacts if your router mounted vertically.

its much better to mix a bit of cyanocrylate adhesive with thermal grease paste if you don't have thermal glue
but i prefer to mask corners with tape before applying thermal grease and put 4 dots of cyanocrylate on clean corners after removing a tape
