CPU Fan full speed

[george93b]

Greetings to all.

I made the new configuration:
- CPU: i7 8700k
- motherboard: Aorus Gaming 3
- ram: Corsair cl15 2x8gb
- ssd: Corsair LE 250
- source: Corsair CX 750w
- Cooler: Noctua NH-D14

The problem is :  I've assembled the components well and nicely. I press the power button and prepare for the first set-up. From the first use, since I started it, the processor fan stays in full speed. After installing the windows, at some point it came back to normal until the next morning, when, after installing chrome, the problem has returning. The idle processor temperature is 30-35 degrees but the fan is still full speed. He has moments when he comes back to normality but not for a long time. I mention that in bios, the temperature indicated is 30 degrees, and as long as it stays in bios everything goes normal, when the windows start fan stays in full speed.

How can I solve it?

half way down on the manual site https://noctua.at/en/products/discontinued-products/nh-d14/faq
as for weather your motherboard has these features I would not know.
Can I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller? You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.

tweek the fancurve it might have been left untweeked forgotten

I have a Gigabyte motherboard just above yours but it is the same BIOS. Go into the BIOS and into Classic Mode, not Easy mode. Then click on the M.I.T tab at the top and you should see your SMART FAN 5 tsettings. Hit this to enter the smart fan panel. Change the CPU fan speed profile to 'normal' or 'quiet' and if it is a 3 pin fan connector then change the fan control from 'auto' to 'voltage' otherwise to 'PWM'. This should sort things out fingers crossed.

I should also mention that you can download the Gigabyte APP Centre for your motherboard and then add SIV to the APP Centre and this will allow you fan control from Windows.
