I have 3 Akasa ambers but 2 of them seems to be broken and giving out loud noises :( Thought all the ambers were like that until I found out one of the three is dead quiet at full thrust (unlike the other 2 which is noisier than the good one even at 5V)
Will need to upgrade 3 fans so need something cheap... No non-uk ebay please.
Cheers
Arthur
