Makes sense, thanks to all.or a volcano 9 with its own speed control for $20.
i know i'm late. but this is my favorite method.Originally posted by Zedric
2. Connect the fan between 5V and 12V giving it 7V. Close enough?
Really? That's got to be some really cheap fans!Originally posted by LeeJend
A decent voltage regulator with heatsinking will cost as much as a new fan with a built in speed adjuster.
the positive lead for the fan goes to the 12v... and the negative lead goes to the 5v... 12 - 5 = 7 volts.Originally posted by XP Abuser
lol
im just trying to think how does that 12v and 5v make 7v **** work
No offence intened!Originally posted by XP Abuser
rub it in then zedric
sure, it still moves air. you can feel it. a fan at 7v runs roughly 60% the speed of 12v. if you want something between 12v and 7v, then i think you're only choice is a regulator or resistor (not sure what the difference is).Originally posted by LeeJend
Doesn't dropping the voltage to 7 Vdc make the fan turn too slow to get enough airflow? My 6800 @ 12Vdc is at 5200 @ 9.5 Vdc.
Anybody got any speed numbers for the 5-12Vdc conenction?
