@Mikeywith, you might want to slow down and re-read the post.
Unlike the majority of members on this forum , I do read every single detail related to the person who is seeking help, I helped a dozen of people here , you telling me this is like implying I simply rush to answer which is never the case.
reading the OP only ( as many people do) is WRONG , there is a newer post in which he states the following.
i cant access the UI i mean it dosent show up on modem router ,
even when i replaced the original fan it is same,
I am not sure if you ever owned a miner, but the control board must get an IP address and show up even without a fan , he must fix this problem first , there is a good chance that there is nothing wrong with the fan, and the only way to know this is to get to see the miner UI.
I am not saying Bitmaxz is wrong and that the fan problem ( if there is any) shouldn't be fixed , but use your common sense, your car won't start and your first priority is to fix the radio, good 'effing luck

While we're on the subject of common sense...
To use your own analogy, if I work on my car and change something and now my car won't start common sense say you go back and check what you did. In this person's case they cut the FAN plug, not the patch cable as you incorrectly ASSumed and even went on to say
So again slow down.
Oh and BTW if you actually read posts here you'd see plenty from me and know that yes, I do own miners.
