Really loud fan with low temperature

I have a Corsair H100 240mm liquid cooler but my fans are really loud, I've gone into the bios and the CPU temperture is 24°C and the Motherboard temperature is 23°C, the CPU fan is reading at around 5500 RPM and the CHA fan at around 1250 RPM both of which are on silent mode. My CPU is an Intel I7 6700K and GPU is Nvidia GTX 1060. Is there a fix to this fan speed or is this normal?

Do you have them plugged into CPU pump block? If so, your motherboard BIOS control means nothing as it is controlled by the pump. It sends that high speed signal to your motherboard so it doesn't freak out thinking there is no fan.

Can you control it with the corsair link software? I got the H115i and found that the fan curve was far too aggressive and based on the wrong thing. It was using the fan profile for CPU temp. It makes sense that it would do that but what is important is the water temp reading. Once I switched it to that it worked better.

That being said, I personally recommend you plug the fans into the motherboard directly and use the BIOS to create a more reasonable fan profile if possible. I removed the corsair PWM fans...

That being said, I personally recommend you plug the fans into the motherboard directly and use the BIOS to create a more reasonable fan profile if possible. I removed the corsair PWM fans (which are extremely loud as you know) and used some fractal design ones that are nearly silent at full speed and just set the fans to always be 100%. I am sure it compromises cooling some but I haven't had any problems out of it yet.
