    Dear

    Could you advise if the hashrate is normal or not ? you can also send us the new full kernel log after the miner running 15mins to double check and send the miner status screenshot together

    Hello, the hash rate is normal, with the old or the new fan, it's the same, as soon as it's hot enough, it goes up to 30,000 .. currently it is 6000/7000 , the image below . Thank u

    Dear

    If the hashrate is affected, we suggest you replace it with an official fan

    Hello, what does an official fan mean? the problem certainly does not come from the fan, with the one before the problem was the same.. thank u !

    Dear

    We checked your hash rate is normal now ,you can ignore this temporarily, if your Fan speed will effect your hash rate in the future , you can buy an official Fan in the bitmain's website to replace this Fan ,

    Dear

    Could you send us full kernel log after the miner running 20-30 mins , after double checked with technical engineer we will advise you the solutions and advice.

    Kernel log will always show the real reason issue for the antminer.
