I thought you needed to leave these as PWM, so that AI Suite 'knows' that these are PWM fans. I found a way to disable QFAN by disabling each FAN in the BIOS. Yes, BIOS is up to date and I am using the latest versions of the software, as I just downloaded them. When I had AISuite unintalled, it was not happening. I think QFan is interfering but I am not sure.ĭoes anyone have any suggestions on how I can disable QFan? Or what may be causing the fans to spin up. The fans some times ramp up for no reason, and clicking on 'Standard' on the Fan Xpert screen controller sets it back.

However, I still find that QFan and Fan XPert are conflicting. Was careful not to run the 5-way optimizer.

It did a better job of controlling the fans, and even shuts them off, when the temps are cool enough. I then tried Fan xPert 4, which is part of ASUS AISuite 3 package. I first tried controlling the fans with QFan in the BIOS, but I was unable to set the speeds low enough. The ASUS motherboard (X99a-II) has quite a few features, but I am having trouble getting it right. However, I am having trouble getting the control right. I have a SilentLoop 280 mm as well, which are also PWM BeQuiet fans.

The goal was to make the system quieter, which it is now with the new fans. I have a define R5 case and replaced the DC case fans with Silent Wings 3 PWM fans.
