even tho 3pin is for DC, i can set it to pwm in the bios , but it's louder than the DC so no use for it,and in the DC settings
i tried that in the curve but the curve doesn't want to go lower than 60% , that is 60% of 1700rpm. so they stay at around 1000rpm i can modify the curve at higher rpm but not lower than 60%. and for me they are really LOUD because i was used to a quiet case. i have an silentiumpc fera 3 120mm cpu fan that 99% of the time run between 600-1000 rpm and it's really quiet even in gaming. but these arctic p14 are advertised at 0.3 sone (22.5-24.5 db) at 1700 rpm ! that's defenetily a lie. they are really noticeble even at 1000rpm. they run at 12v most likely.
