I tore off my gpu fan connector...

So I was trying to repaste my gpu for the first time and I mistakenly tore off the whole 4 pin fan connector on the gpu. I know I can attach fans to the heatsink and connect them to my motherboard, but I was wondering if its possible to desolder the remaining bits of the pins in the gpu and solder a replacement connector to it. I tried looking on amazon and aliexpress and I couldn't find it, does anyone know what they're called and if I can buy them? Luckily I didn't make the same mistake with the rgb connector and I saw that there was an unused connector next to it but I dont know what the extra connector does. This is a gigabyte windforce rtx 2070 super, and it says j604 above the unused connector. Could I desolder it and replace the fan connector with it?

Tldr:

1. Where can I buy a replacement 4pin gpu fan connector to solder on

2. If I can't buy it, can I desolder the unused connector and replace the fan connector with it?
