Does the 2020 or 2018 Razer Blade (Base) Heatsink fit on my 2019?

Hello dear Razer-Fans! Sadly i made a mistake and tried to plan down the heatsink surface because of certain hotspots i have on my cpu die. i tried to fix it but will bite the apple (get it?) and buy a used heatsink over ebay. https://www.ebay.de/itm/384158427140?ul_noapp=true this one looks exactly like mine from my 2019 base, but apparently is supposed to fit a 2020. Could anyone confirm if the heatsink got important changes in those years and couldnt fit? Thanks in advance! Greetings from germany, Kevin
