If its a 3pin its a DC and if its a 4pin its a pwm? How do I tell if my board can automatic vary DC fans per load like pwm, or does no board poses that ability? Are DC all manually adjusted via bios and or controller? Do spliters allow dc to pwm?
Idk if you seen the review from 2012 on TH
Looks like the cooljag R121425SL is quite the beast, rather noisy at full tilt, 33db/110cfm @ 1500, but Im wondering what the specs are @ 900-1k. Not sure what variable DC fans have, what I understand is you adj the voltage, which are usually in increments of 3 (low/med/high), are the voltage increments adjustable? It'd be sweet if my board can adj DC fans like pwm fans. My board is an AsRock Z77 OC formula btw.Edited by MoPar Kid - 8/4/13 at 6:16am
