The fan bracket is used to fix the Whatsminer 14cm cooling fan. It is made of aluminum alloy, which is anti-corrosion and wear-resistant. If the bracket is damaged, the cooling fan will not be able to be fixed, and it will fall off during operation, affecting the miner's regular operation. If the screws of the fan bracket are loose or fall off, it is recommended to replace them immediately to ensure the regular operation of the miner.
