4 pin fan connecting to 3 pin socket

[VanillaM123]

I recently bought the Noctua Nf-f12 industrial PPC fan but my motherboard (asus m5a78l-m/usb3) only has one 4 pin fan connector (for the CPU cooler).

I know it's possible to connect a 4 pin fan to a 3 pin socket, but the speed will not be controllable. The problem is that the fan running at full speed is incredibly loud.

Is there some sort of adapter that would allow me to control the fan speed, or will be speed be controllable using a program such as speed fan, even though the 4th pin is not connected,

thanks in advance

You will receive satisfactory results going with this adapter. Installation is simple by connecting it to your motherboard fan header and then plugging all your fans to the splitter/hub. This would be a step above going with a low voltage adapter or going with a molex adapter where in either which case the speed is fixed(high or low).

You're next step would be to go into BIOS and set your fan profiles for you CPU fan or the chassis fan header.

Why do you say the fan speed will not be controlled? Have you tried it? My understanding is that the backwards compatibility of 4-pin fan design means it WILL run when plugged into a 3-pin fan port in Voltage Control Mode, AND its speed WILL be under mobo control.

It's the other way around - 3-pin fan on 4-pin PWM port - that always runs full speed with no control.
