illuminarti 16 Posted June 11, 2014 in new um2 fan problem No, it's fairly normal for these fans to resist starting at lower speeds. The firmware should do a better job of kickstarting them. Usually if you just get them started by hand they will spin up ok. But to be honest, you really only need to run them at full speed for most things. Share this post Link to post Share on other sites
