May 2, 2013 - On my P8Z77-V Pro, Q-Fan can control 3-pin and 4-pin PWM fans on all chassis fan headers. You have to use a 4-pin PWM fan for the CPU fan(s) only; if you use 3-pin on the CPU headers, they'll run at 100% all the time. To answer the last part of OP's question, if your fans are plugged into a hardware fan controller, Q-Fan will have no effect.

May 2, 2013 - Hi everybody, I just build a new rig. The motherboard I chose was the Asus P9X79 Deluxe and I was digging in the UEFI/BIOS and came across Chassis Q-Fan Control option. Now.. there is also a CPU Q-Fan Control and I know what does that do - it regulates the Fan of the CPU. I had mine...

Enables the Chassis Q-Fan control feature.

April 9, 2012 - BIOS (see pages 3-28~3-29): CPU Q-Fan Control -> Enabled ; Disable IF you have a 'pump' i.e. Corsair Hydro series connected CPU Fan Profile -> Silent ; not the best IF OC'ing the CPU; IF OC use Standard or Turbo CPU Upper Temperature -> 60C/140F ; try different temperature thresholds. Chassis Q-Fan Control -> Enabled Chassis Fan Profile -> Silent Keep in mind as the load and subsequent temps go up so will the fan speeds.

February 25, 2023 - Hi. I'm using TUF GAMING H770-PRO WIFI MB, and UEFI Q-Fan Control doesn't show an option to stop chassis fans in PWM mode but allows me to do this in DC mode. Is this restriction intended or a bug? Fan Xpert4 within the Armoury Crate allows to enable "Auto-Fan Stop", but only when "Extreme Quiet Mode" is enabled.

December 4, 2014 - That lets you control it with speedfan-- provided speedfan has those PWM modes set to "Software Control" -------- I found a solution-- You can't get around the CPU fan header requiring PWM, but who says you have to plug a noisy fan that actually cools the CPU into the CPU fan header? Since it runs at 100% I plugged in my quietest fan to the CPU fan header, but it's actually just a case fan. The rest of the Chassis fans are on the same voltage plane, but they can be software controlled via IT8721F's PWM3, so I just plugged my actual CPU fan (still 3-pin) into one of those; the rest are chassis fans behind and above the CPU.

March 6, 2024 - In the UEFI there are some controls that I am currently trying to setup because I got some new 4-pin case fans and I want to utilize the PWM that these fans can do. But one option in the section of fans is "Chassis Fan 1-4 Q-Fan Source", there are many options (default is CPU) and reading the ...

November 28, 2021 - When I enter to the Q-Fan control screen in the BIOS, I see the Stop Fan checkbox, but it is disabled. The fan is working, and the BIOS seems to be detect it and its RPM. The fan has 3 pin connector, which is connected to the mobo' 4 pin connector. ... Check with ASUS Supports. The fastest way to kill a CPU / GPU is to turn the fan off. ASUS may force it to stay on. ... I agree, although it is the chassis fan, not the CPU fan.

May 13, 2012 - You may enable all the items since your cpu supports them. Q-fan should keep the cpu fan noise down if you don't like the setting now. I use the "quiet" setting after calibrating the fan.

The Q-Fan control allows you to set a fan profile or manually configure the operating speed of your CPU and chassis fans

This item appears only when you enable the Chassis Q-Fan Control feature and allows you to set the appropriate performance level of the chassis fan.

January 24, 2023 - Hello everyone! My chassis fan 1 minimum duty cycle is at 60% while chassis fan 2 is 20. I would like to make my pc quieter by creating a new fan curve but I can't go under 60%. I have tried optimizing all and that didn't help.

August 15, 2020 - Click to expand... would you say the rpm for the case fans are normal? And the cpu heatsink is pretty screwed in ... Your temperatures are OK. The fluctuations are normal, because some apps are running in background ( virus checker, rgb-controlling software like razor synapse, corsair iCue etc. - depends on your components - you can check it in task manager). My CPU- and chassis-fan-settings are manual ....

March 6, 2024 - How come ASUS motherboards don't allow manual DC Chassis Q-Fan Control to be set below 60%? I notice this was also true with the Hero Z170, but I was able to work around this in the advanced monitor settings (and as long as I didn't ever go back and change anything in Q-Fan Control).
