IS ANY CHANCE TO MOD FIRMWARE ON Z9 MINI TO ACCEPT ANOTHER COOLING FANS?
one of my z 9 mini cooling fan stopped working, i have Delta electronics same spec fan but my mini wont accept this fan and boards not start hashing. anything can do?
p.s. if put fan simulator on 1st fan connector and add as second fan then asic start but cant get full speed on fan only 4000(fan is 6000 rpm)

You may need to check the RPM wire and make sure it is on the 2nd pin from the left when the miner power connector is closest to you. The PWM and RPM are sometimes switched on other fans. If you leave it on there like that too long you may burn out the RPM signal line. Learned that from experience.

no fan pin outs are identical rpm are same, just z 9 mini wont accept another brand fan as original one is SF fan not Delta electronic,for sure these fans are used in antminers but another models not z9 mini problem 100% are on firmware have seen on youtube same problem when ppl try to change original fan to another better or similar
