Hi all! I've recently moved to b550 f gaming and I see the option Q Fan. And I was wondering should I just leave this option as it is as default settings or should I go into q Fan tab and click optimise all and then save the settings ?

Does clicking on 'optomise all' make any difference in performance ?

Which option is better ?

I just found a awesome feature that my ASUS motherboard has!, I find that when watching youtube videos my cpu and extra fans seem to fluctuate rpms making them produce this annoying jet engine start up and its really noticeable on youtube videos that only has the person speaking, I originally planned on setting the fans to a lower rpm as to not annoy me when watching videos, so I rebooted into the uefi and go to fan control, I notice there is a optimize button and thought "hmm why not give it a go cant hurt the system" I tried it and let it do its tests and I was mind blown the fans are so quiet its CRAZY! the temps on my cpu are only 2 - 3 C higher but thats a sacrifice Im willing to take for SILENCE!, so Guys and Girls check if your motherboard has this option and it could fix the annoying jet engine sounds!

Hey Everyone,

Finished a new build, curious but are we supposed to use ASUS Q-Fan control and hit "Optimize" in the BIOS or is it better to ignore as the board has AI that will handle it? Or should I leave it alone and use a trusted fan control app if needed?

The board is the ASUS B850-F and a Ryzen 9950x3d w/ a Noctua DH-15 G2 cooler in a ASUS ProArt PA602 case.

Some threads said you should so the system can understand the max speed the fans can hit - is this true?

Sorry its been 9 years since I built a new pc - unsure atm :/
Also - is it better to do fan optimization in the morning after the pc has been off for the night to get a better read or does it not matter?

So I was tweaking fan curves when I decided to use the "optimize all" option the bios had available, I did this twice (because after the first time I tweaked the "manual" setting without knowing that the optimized fan curve was implanted there) which caused almost all my fans to fully stop for several seconds, and then spin back up to reach 40 c idle for cpu both times.

I didn't really like these settings, and while it was more quiet, I would rather not have higher temps so I put it back to where I had it before.

However, I noticed that even when playing cpu bound games, the gpu usage would be considerably higher than what it normally was before the optimization process, and so was the temp, which stayed at a consistent 50 c on old games like tf2, 10 degrees higher than what it normally was before.

Thing is, the cpu temps stayed pretty much exactly the same.

TLDR: all I want to know is if I've damaged my gpu by using the fan optimization in bios which stopped my fans for almost a couple seconds twice in a row.

cpu: ryzen 5 5600x

mb: rog strix b550-f gaming

gpu: sapphire nitro+ amd radeon rx6700 xt

case: lian li lancool 2

It's a pre-built gaming PC so not sure if the company had set certain fan speeds/curves before delivering.

Hi all,

I'm using 6 120mm xspc rgb fans connected through a 12v xspc 4-pin pwm hub. The hub then connects to chassis 2 fan header on an asus z390-e motherboard. The fans are rated for 800-2200 rpm. When I set the fan curve to the very minimum speed (20% i think), for some reason the fans start at 1240 rpm... I was confused at how it started at this speed but after some guessing I figured its 800rpm+(20% of 2200) which comes to 1240 rpm. Is there a way to set the minimum speed at 800?

Thank you so much and please let me know if I need to clarify on anything!

So I posted here a few days ago asking some basic overclocking questions as I was worried with the stock cooler I was working with for my new i7-9700K. I recently installed the Noctua NH-D15s onto the CPU, which gave me a cooler score of 175 or so I believe, but I was very confused to see that I was getting a CPU Fan Error...The fan was spinning and my temps were super low so it was obviously working and functioning properly.

Come to find out, I had plugged it into the wrong slot. I plugged it into the Maximus Hero XI (Wi-Fi) Board's AIO Pump power slot and not the one for the CPU fan. Keep in mind I had ran Cinebench several times with it being plugged into the AIO Pump and ran ASUS' 5-Way-Optimization and AI overclocking which gave me the aforementioned cooler score and a suggested overclock of 5.1 ghz. I was happy! The cooler was worth it and I got the overclock I needed. Temps were low, everything was fine.

But, I still wanted to monitor my CPU fan usage, RPM, etc. and was confused as to why it wasn't showing up. So I checked the mobo and, as I said, it was plugged into the wrong slot. So I switched it and expected even better results. This is where it gets weird. I ran Cinebench, 5-Way optimization, and AI overclocking yet again and not only had my cooler score dropped by 20 points, but, subsequently, my overclock was limited to 5.0ghz! Trying to do things on my own led to a 5.2ghz overclock but with my computer restarting itself whenever I ran any game for more than 5 minutes.

Why is this happening? Why is it that if I plug my CPU fan into the AIO Pump power that I can achieve a much higher cooler score and therefore a higher overclock, but when it's plugged into the proper slot, it gets worse?

I am using a TUF X570 PLUS with a H115i and the damn bios won't let me set the pump fan speed at less than 60%. It is a standard 3 pin header (which means it is DC?). If it were a PWM, the minimum would be a much reasonable 20%. Setting it to either with manual mode doesn't make a difference anyhow. Can I edit those default minimum values?

EDIT:

thank you u/-UserRemoved- and u/coololly. I understand now that Q-fan control is useless here. But for some reason it seems like iCUE undereports the RPM speed. When I check with HWMonitor, I observe a much higher number which seems more accurate to the noise level coming from the PC (4400 vs 2300 RPM). Is this buggy software from Corsair or maybe a pump issue?

Hi all. Hoping someone can help me out with a motherboard issue. I have an ASUS Z97-PRO (Wi-Fi ac) with a Corsair H100i cooler.

For 5 years there haven’t been any problems (since the initial setup), but suddenly last night my motherboard has decided to enable Q-Fan control in the BIOS. As my cooler is a closed-loop liquid cooler, there is no “CPU fan” so upon booting, I get a CPU fan error.

Once I go into the BIOS and disable Q-Fan control, everything works as normal. Trouble is, despite me “saving” this setting when exiting the BIOS screen, if I fully power down my PC (I usually switch off the mains power at night) the motherboard decides to switch Q-Fan control back to “auto” and I get the CPU fan error again the next time I boot up.

Is there a reason why the setting isn’t being saved? Am I doing something dumb? Does anyone know why this just started happening? Why do I have so many questions?

Thanks in advance!

So while messing in BIOS due to my pc overheating and my case fan not working I saw I can tune the speed of my CPU fan: standard, silent, turbo, full speed and manual. Do any of these help with an overheating CPU? Is it smart to change it from standard to something else?

Is PWM or DC better for Gaming and also what are the optimal bios settings for highest Performance (ASUS UEFI BIOS)

All my life I've only ever built and put together middle of the road computers that are usually two generations behind on their CPU and GPU. As a result I never really needed to worry much about temperatures and never picked up much knowledge in regard to cooling. After a lot of saving and financially responsible decisions, I hit a point where I felt safe going all in on a machine just this once for the fun of it, and so I've just built a new computer with specs that actually mean I want to pay attention to temperatures. I'm affectionately referring to it as my mid-life crisis computer.

So my question is, in regard to the longevity of parts, what's my best bet for fan settings among the following using Fan Control v157? I don't really care about noise since I'm using a decent set of noise cancelling headphones, my entire concern is the long term health of the components.

1. Just flat, 50 or 75% fan speed around the clock

2. Flat plateaus (ex: 33% power between 0 and 45C, 66% power between 46 and 60C, 100% power at 75C and above)

3. A straight line "curve from 0 to 100% with a single minimum and max temp

4. An actual curve.

The computer: I've got a i9-13900k, 4090RTX FE, 64gb of RAM, and 6tb of NVME.2 4th gen. My cooling setup is a 360mm AIO positioned to exhaust out the top, three 140mm intake fans, four 120mm intake fans, and a single 140mm exhaust fan. The case is a Corsair Airflow 7000D.

Side note in case it matters: I've power limited the CPU to 200 watts so it maxes out at 77C under load (it was shooting up to 100c instantly under load tests at stock settings, hot tamale). The GPU is running stock settings since the FE seems pretty well optimized out the box and I'm not doing anything other than gaming with it.

Basically title. I want to use fan control software so I can have smoother fan curves. Would I need to disable bios fan control completely or will the software fan control just "take over" once I'm logged into windows?

Thanks!

I'm having a hard time understanding how to optimize the fan curves in fan control, any recommendations? Noise is secondary but i dont want jet fans either lol.

I have a lian li 217 case with 5 built-in fans and a thermalright PS 120 Evo. Also with the current build, all case fans are controlled together through the case fan hub, i should probably divide the connectors if i want more individual control if that's more optimal.

Hi All,

I have a ROG Strix B550-I with the latest BIOS, on which I have connected an NZXT M22 AiO. The AiO has a 3pin header and is connect to the mobo's AIO_PUMP.

My goal is to control the pump speed from inside the BIOS and without the need of any software, but apparently I'm missing something...

When I set to the Pump to PWM mode, it will continuously run to 100% no matter the curve I set on Q-Fan, and when I set it to DC Mode I can reduce to 60%, which is still quite noisy for my standards. From what I've read, both of the above are expected. The behavior is the same even if I connect the AiO to the mobo's CPU_FAN or CHA_FAN headers.

What surprises me though is that if I install ASUS AI Suite 3, I can adjust the pump's speed to whatever curve I want with minimal performance losses, but impressive noise reduction.

I know that adjusting the pump's speed can impact its estimated life, but I'm willing to take that risk. Am I missing indeed any BIOS settings, or is setting a curve for your 3pin AiO possible only via software?
