Constantly changing fan speed

[samuel990705]

Hey guys

 

Just finished my PC build not too long ago. Here is the part list: https://pcpartpicker.com/list/T6NY6X

 

However, I am finding something really odd. The fan speed continuously fluctuates, almost like it is pulsing. I have a few hypotheses for why this might be happening.

1. I did not connect the CPU fan's rpm control cable to the CPU_FAN header on the motherboard. Instead I connected it to Corsair Commander Pro, and control it through the Link software instead.

2. I am running multiple fan control software. I have Corsair Link, NZXT Cam, and Asus Ai Suite III. I mainly only use Corsair Link, but could the different software be "fighting" for the fan control?

3. I have not adjusted the fan curves at all.

4. Fan rpm could be dependent on CPU temperature, which is constantly fluctuating.

 

I am unsure which fans are constantly fluctuating. Maybe its only the radiator fans. But I am pretty sure all of them are constantly changing.

 

Any help is appreciated. Thanks very much guys <3

Uhhh, You should really connect the CPU fan to the motherboard

Also, both Corsair Link and Asus Ai Suite III are saying that my CPU fans(MB fans) are running at 3400 rpm. This is kinda odd cause I didn't connect any fan to the CPU_FAN header on the motherboard. 

 

Temperatures seem to be normal. CPU temps are usually below 40.

Your fan curve might not be set up correctly, usually you would get a CPU_FAN error if you don't connect a fan to that header so that's a bit weird as well.
