Some fans are not recognised and do not work.  Some fans work but trigger the "fan isnt working properly alarm on the QNAP"

NAS Fans can stay powered on constantly for years.  You should purchase the original fan that went in the machine if your fan has failed

built to last

check the part number to make sure this is the right fan for your machine
