Hello Javier,
thank you for contacting our support.
We will gladly inform you below the info, you need.
Unfortunately, we are not able to provide any thermal pads, which can solve the problem.
However, here are the Infos, where you can get the thermal pads from the right retailer.
The thickness of the Thermal Pads are 1.25mm and
we recommend to a solution, which provides 1.2W/mK thermal conductivity and more.
If you have any further question, please contact us again.

I guess I have to spend 10-15€ to buy them... I really though evga would send me them as its a manufacturing defect.
