I have an IO XT and I use it for editing with Avid and Final Cut.
After a while the XT starts spinning up it's fans and they don't slow down until I turn off the iMac.
When I start editing again it will spin up again after a while.
The first XT I had got extremely loud and I changed it for another XT.
This one is not that loud but it is still very distracting.
Is this normal or do others have XTs that don't spin up their fans all the time?
