Just replaced my logic board and everything seemed great.. got my Mac out of the dark and running again but fans are at full speed. Tried ssd fan control also with no luck. All connections seem ok. any help greatly appreciated

its all connected as far as I can tell… I literally took it all apart again:( Frustrating cause it’s works great otherwise. i may just have to run the fans with the Mac fans control
Did you put back the HD thermal sensor onto your SSD? Review Step 20 in this guide iMac Intel 24" EMC 2134 and 2211 Hard Drive Replacement Transfer it to your SSD drive and reconnect it that should fix things.
