If the card is defective and only a month old, you have an RMA option.
This is the answer from German Gigabyte support:
Dear Sir/Madam,
There is no warranty claim which was agreed that the card would be replaced. We do not replace any products for first RMA only repair. If you want a refund, please contact your original supplier of the graphic card. The test result claim that the sound of the water pump is on a normal noise level and not considered as defective.
Mit freundlichen Grüßen/Best regards,
RMA -Team
They sent me the card without any explanation, they only replied when I asked for an e-mail and kicked me out of the chat and closed the chat.
THIS COMPANY IS ONE GREAT JOKE, I WILL NOT BUY ANY MORE FROM THIS COMPANY.
