I got 5 new Cooler Master Jetflo fans installed in my pc yesterday which is all well and good but the thing sounds like a jet engine when it's running now. I tried installing speedfan to check what rpm they were running at to maybe turn them down, but they aren't even getting detected by it. I know there were only 2 connectors on my mobo (Asus Prime B250M-A) so not sure if the guy split the connection on plugged directly into psu... Thoughts/ideas?
