Remember that the GTX10xx series was released and launched in August 2016, that´s almost 5 years ago. It´s successor RTX20xx came in 2018 and another 2 years later RTX30xx. 5 years in IT and technology is really a long time. How many different versions of spare parts should they have in stock?
Better disassemble the GPU and check the pads. Have a look in your favorite stores and buy a suitable set of pads.
Good luck and stay safe and healthy
