After like 2 months of trying to get the right thermal pads pot my gpu, my next not-so-expensive alternative is this
(this is a work in progress, I know is missing some heat resistant tape and the thermal paste and clean very well the copper sheets)
Edit: for extra context this card specificaly uses a very specific thermal pad thickness and hardness, it uses 0.75mm thick thermal pads or 1mm wit a hardness of 25~30 shore OOO, and the softest ones i could get were the arctic tp-3 with a hardness of 50~60 shore OO, it's way too hard for the card, and actually bends the pcb
