Fans too loud

[ajitesh1500]

I've just installed my new Noctua NH-C14 and noticed that its running very loud. I checked it using HW Monitor and saw the fans are running at a constant 1170rpm at both 0% load and 100% load. The fans are not PWM which I guess could be the reason but I've heard that fan control is also possible on 3 pin fans. I looked in the bios but didn't find any useful fan adjustment settings. All it could to do was adjust the max and min threshold (min by default set to 250rpm but still running at 1170rpm). I have an Intel DZ75ML-45K motherboard. If someone could tell me the steps to adjust DC fan control on my mobo that'd be great. I prefer to set a custom fan curve if possible
Thanks in advance

There should be a low noise adapter included!

Yes but i want it to perform good at high temps. With LNAs too it is stuck at 800rpm and wont vary with increase in temps

You can use 3rd party software called Speedfan.
