Hello,

I have an Octo with 4 Noctua fans (2x NF-A14 iPPC-2000 PWM + 2x NF-F12 iPPCF 2000 PWM), a Swiftech PWM DDC pump, and water temperature sensor probe

I have set in Aquasuite a custom curve for the NF-A14s and NF-F12s to increase speed based off of water temp. After a certain water temp, I have the controller signal 100% power output. However, the 140mm (NF-A14) fans only get up to ~1650 RPM with this curve set, even at 100% output. If I choose "Power preset" and do 100%, the RPM is ~1860.

I would like the fans to basically spin at max RPM when the curve is past a certain water temp but the 140s do not ramp up all the way with the custom curve. The 120s are fine.

Can anyone help me understand why even at 100% power output under the "Curve controller" the 140s do not spin up all the way?

Thanks!

This fans are not compliant with the Intel PWM Control standards, try other fans or contact noctua.
This is a fan issue.

Thank you for the info! Not a huge deal I suppose. I'll just set up automatic and manual profiles for times when I want to have the fans run at max speed, which can be done by just choosing "Power preset" and setting that to 100%
