Break in period
Though it's not mentioned in the manual Carlos has spoken of a break in period. I assumed the break in should be done at lower speeds but it seems I was wrong. Carlos says the break in should be done at a minimum of 40%. I've been running mine at 30% and it was pretty much silent. When I run it at 40% or higher I get a high pitched whine. I'll run it at 40-50% for a few weeks and hope that whine goes away. Anyway, run it at least 40% to break it in properly.
