Hello & thank you for you review. I understand how frustrating it can be for a miners hashboard to break so quickly. We hate to see things like this happen, your miner should be covered under Bitmain warranty. If you need assistance in figuring out how to open a repair ticket with Bitmain, please message our support team and they would be happy to direct you. Altairtech.io

Shipped very fast. Clean packaging, they actually thought it through. Whoever can shrink wrap 4 fans at once is a wizard. Very good customer service without high pressure sales. Thank you!
