Changing Voltage Of Delta Fan?

[LobazaJ]

so i just added a corsair H60 removed the stock fan and added a Delta AFB1212GHE-CF00 120mm Case cooler.. Very Very Loud Looking to change voltage from 12 to 6 how do i go about this

G.SKILL Ripjaws Series 16GB (4 x 4GB)DDR3
ASUS GeForce GTX 550 Ti (Fermi) 1GB 192-bit
AMD Phenom II X4 965 Black Edition Deneb 3.4GHz
OCZ Fatal1ty 550W Modular Gaming Power Supply
CORSAIR Hydro Series H60 with Delta AFB1212GHE-CF00 120mm
Stock Essentio CM1730 Motherboard

Swap the pins in the 4 pin molex to run 5V or you can swap the -12 with the -5 and make 7V
I ran my delta at 5V

 

[Mussels]

you can run 5v or 7v by changing the wires around, you wont be able to get 6v

You could consider wiring in a pot between +12v and the load.

i just made this is this right?

Wire it up like this diagram.

thanks man works great 10+ degrees difference on idling temps tho big difference between 12v and 7v at least my PC is not gonna take off down the runway now lol

Next time buy one that is PWM compatible and you can use the motherboard to set fan speed

Maybe his motherboard doesn't support it, but mine will let you control fan speed by using just voltage and optionally being able to use PWM if the fan has it. In Windows the software will try everything between 0v and 12v while it records the fan speed for the different voltages. It lets you control the fan speed at certain temperatures based on based that.

Even with my last motherboard which was 4 years old, it would give some at least some static control of the fans, granted they're both ASUS boards. I would find it hard to believe that ASRock doesn't have something like that, even on an older board.

With that Delta fan you would just instantly fry fan headers of your board, that takes 2.45 A while most boards only support up to 1 A

Be careful with server fans, they can draw a lot of amperage. I like to run them straight off molex instead of fan mobo headers. I like undervolted server fans over consumer fans any day.

I've been running this fan off the PWM header on my board for about a year with no problem. However, I have it set so that it almost constantly runs at ~25% and never goes over 40%. The current draw would be slightly over 1A at 40%, but that shouldn't cause an issue since it only occasionally peaks to that.

With a powered pwm splitter you could safely run it at any speed with no risks to your board

I know, I just haven't got around to buying one.
