Simon Bridges 0 Posted August 8, 2015 I am currently having issues with my Cosmos II if I use the standard case fans that are pre built onto case the fans are nice and quiet but the second I plug 3 additional Cooler Master SickleFlow Fan's onto the cosmos 2 fan controller the additional fans will make a very loud rattling noise if the fans on low speed or medium speed, so I was wondering if there is a way to stop them making this noise ?
