If you have a converter that's NOT a WFCO, it may not function like the above. If it's a WFCO, it's a variable speed fan. If your fan is "annoyingly loud" you might want to dig into the converter and clean the fan. If you've got pets (or if Keystone didn't clean out the sawdust) you may have some debris on the fan blades causing them to "wobble" which makes them far too loud to ignore.....
