Why are my CPU fans running at 2300 RPM 24/7?

I always thought my PC was a bit loud, but figured it was because I got the Corsair High Performance fans over the quiet fans. However, I downloaded SpeedFan which is reporting that my fans are running at 2,300 RPM. That seems a bit high to me, since I am just browsing the internet. Any clue why this is?

Check your BIOS and see if they are set to always run at full capacity.

How did you setup the fans? are they all plug in the same header with a splitter? Did you set a curve for the fan speed?

Well, my H100i has two fans attached to a header with a splitter (That was included with the H100i). I did not set a curve. I tried looking for a way in the Corsair Link software, but didn't find anything for it.

Check your BIOS first, the default often set the fans at maximum speed. Also, are they PWM fans? Not all motherboards can control non-PWM fans.

These are my fans. They say high performance at 2350 RPM.

I will check BIOS though. I ran an AISuite test where it starts at 0% and makes it's way up to 100%, but noticed no difference in noise or temps.

Potentially this. Although you have a pretty new motherboard.

I had this issue. I eventually just bought a fan controller.
