Q：Hi, my Octominer fan just died and I only need 1, is there a way I could get one without buying 10 Willing to pay extra since it#39s only 1
A：Hello, the cooling fan is a vulnerable part in the mining process. After the miner has been running for a long time, the fan will age or wear out, affecting the heat dissipation efficiency. It is recommended to keep it in stock. You can contact our sales manager via WhatsApp (+8618623251355) and email ([email protected]) for more help.
