D14 Help

The 4th pin is used for PWM (fan speed control via BIOS). If it's not connected you won't get automatic fan control. The fan will run at full speed all the time. Nothing wrong with this, the fans with the NH-D14 are still quiet at full speed. If you want them to run slower, Noctua does include adapters.
If you connect the fans without the UNLA connectors the fans will run as fast as they can at all times. Problem solved.
Some motherboards do have a shutdown temp you can set in the BIOS.

If you have an Asus mobo you can do it using the Asus AI suite II that comes on the Driver disk but it's best to download the latest version from the driver downloads section for your motherboard on the Asus website.
In the Asus AI Suite II there is a tool called FanExpert, as long as the fans for your noctua are in the CPU fan header, the one to the left of it or the one near the back of your case you can control them using profiles, I use the silent profile on mine and I can hardly hear my D14 over my case fans.

Well it definitely works on my motherboard, I don't think I can change the speeds in the BIOS but I know using the AI Suite works because it's what i'm using.
ok I'm back... works geat, with prime running it did not went over 47 °C (with U.N.L.A.)
@SieB: I'm sorry for you but it does NOT conrtol anything!!! I can even see the proof in your screenshot, if at the numbers for rpm you can see that they do change just a bit... and random not going up by incresing more foltage. So sad face for you but your D14 is running the same speed and noise all the time

It works for me, I can hear the difference from setting the profile to Turbo and then setting it to Silent. It's not working properly if it's not changing speed for you.
You won't notice the difference if you are doing it while prime is running because the fans will be set higher because the temps are high.

^^ of cause you here the difference... you have pluged it into a chassis Fannot the cpu one... so if you pluged it into the cpu 4 pin header and than change the speed of the case fans it makes a difference... but not for the d14
I don't have my case fans plugged into the motherboard I have them on molexes strait from the PSU at 12v, only the fans on my D14 is connected to the motherboard. So the only thing that FanXpert is controlling is my D14, thats how I know it works.
If I set the profile to Turbo I can hear the fans speed up and get louder, if I set it to Silent I can hear the fans slow down and get quieter.
