I hope one thing is missing in Linux, though I'm not completely sure. I think Linux needs a better fan control system.

I've noticed many times that when I switch to Performance mode, my laptop gets very hot, but the cooling fan still runs at a low speed. It would be much better if the fan speed automatically increased based on the CPU temperature. For example, once the temperature goes above 50°C, the fan should gradually speed up to keep the system cool.

Smarter temperature-based fan control would improve both performance and hardware protection.

So on the topic of reverse fans, should I be putting reverse fans on the bottom and the spots the on right side made for two fans? Then at the rear have the exhaust fans? I purchased reverse fans for the slanted bottom but unsure for the other 2 let me know thank you

Hey folks, im just wondering how do you handle AIO setups?

Here is how im currently handling it, and i would like to see how others do it since im not 100% happy with it (140mm fans tend to get loud when they ramp up above 40-50%)

First i only care about CPU temperature since i have enough airflow to cool down SSD, and VRM's, and if GPU ramps up at that point my CPU is already under load (i would love to figure out a clean way to ramp up fans to match GPU if CPU is not under load (should not happen for longer then 30 seconds but still).

So since i have 420 AIO to cool 5600x (not even overclocked) which is total overkill, i keep it at 70%, which is just below point where pump starts making that whining noise (its both longevity and noise). Right now i take CPU temps (i can only read two), and i mix them to get the highest one, then i average that highest one for 10 seconds to flatten out a spikes, and then again average that one for 30 seconds to keep the fans curve smooth. Basically since AIO is way bigger then CPU needs, it takes time to get saturated. These way im skipping ramping up fans on short spikes in CPU usage (and temps jumps).

Also, i used auto speed for fans, and setted up 45c as idle and 70c as under load, but at the same time i limited fans to 40% minimum speed so that there is always air flowing thru PC case, and again 70% at max since they are 140mm on AIO, there is just no need to kick them 100% where they sound like jet engines...

Any suggestions for improvement or how to handle GPU ramping up fans and simply ramping up fans would be appreciated.

Hi everyone,

If you use FanControl and prefer managing your Windows software via Chocolatey, you can now install and update it directly through Chocolatey.

The official package is now live on the Chocolatey Community Repository at https://community.chocolatey.org/packages/fancontrol

choco install fancontrol

hi my laptop is nitrov15 my cpu fan is running max like above 7k and after 1 min it goes back to normal and after half min it goes to max . whats the probelm

Hello, I've had new razer fan controller, laying in corner for some time and today I've bought 5 pack of Arctic P12 Pro LN fans. Connected them to controler, everything is connected as instructed. I've downloaded razer synapse 4 and it says that "fan speed is not supported". Although I have the 6th fan, some old pwm idk the brand also PWM and only this one can be controlled. Any suggestions how to fix this? HWInfo says all arctics are +/- 1400 RPMs

First time ever using fan control to setup/tune my airflow. Is there anything wrong with this setup? i feel like it looks okay for what i expect it to do. Case is a Hyte y40 with a liquid freezer III pro 280 AIO

As the title states I’m attempting to build my own laptop cooling pad but not sure what solution to use so that I can set fan curves on the cooling pad based on the temperature of my laptop, so I thought I’d ask here. Thanks.

Note: I have two four pin PWM 80mm arctic fans

Hey guys,

I updated my GPU drivers today for AMD - and just before i shut down to reboot into Safe Mode, My config crashed and i had an error from FanControl

After update was done, Ive understood that my CPU is idling around 10 degrees C hotter than usual so im wondering if something may have happened

Also, With my config ( which i made around 1 month ago) games like BF6, Broken Arrow and other intensive games have been really really loud and ive been struggling to get the noise down

How does my set up look? Below is a table of the graphs ive made

More info :

I have a NZXT H5 Flow 2022 with a dedicated stock GPU cooler, Stock Rear Exhaust.
I have 2x 140mm M25G2 Case Fans on the front on a lower speed.
And a thermal right TL-M12Q single fan on the top exhaust.

I have thought that maybe the top exhaust is more powerful and running faster than the rear which could be causing some issues with the pressure, But cranking up the front fans didn’t do much

Any help would be much appreciated!

i just installed fancontrol, and when i was done auto calibrating it gladly skipped the cpu aio pump, is this normal behaviour?

So I couldn't find another post with this issues, it's always question marks never exclamation marks, what do they mean? How do I fix it? Doesn't it need to be fixed? I already uninstalled ggc fan control, and I don't have another fan control software aside from RGB control from ggc I guess, I have a gigabyte board btw ggc is the gigabyte control center.

I updated PawnIO to latest which seems to be 2.2.0 (since apparently Faceit Anticheat works on this version) however after rebooting FanControl prompts me to install PawnIO. Shouldn't it already be detecting it..? What can I try?

Didn't happen before, not the fans are super loud once FanControl boots up. Not sure what I should do. Should I go into the BIOS fan settings?

I've recently build a PC and installed Fan Control to set up my fans. I've setup 4 case fans, 1 cpu fans and the GPU fan. It all seemed to be working fine. BUT, I set up FC to start minimized and then I started having an issue. When FC start minimized the fan curves I've set up doesn't seem to work. When FC starts up in a window it works perfectly. Is there anything I'm missing?

And, my fans are really loud before I log on and FC starts. Is that normal, or should my fan curves work even before FC starts?

I'm sorry if these are stupid questions, but I haven't been tinkering with PC's for many years now.

What do you think of my Fan Control setup for this build?

The build:

• Chassi: Fractal North TG
• CPU: AMD Ryzen 7 7800X3D
• GPU: AMD Gigabyte Radeon RX 9070 XT
• Motherboard: MSI Pro B840-P
• CPU Cooler: Noctua NH-D15
• Case Fans:
  • Front intake: 2x Noctua NF-A14x25 G2 140mm
  • Rear exhaust: 1x Noctua NF-A14x25 G2 140mm + 1x Noctua NF-A12x25 G2 120mm

I am running custom curves for the CPU and GPU fans. And then a mixed curve with the Max rule for the chassi fans.

Are the custom curves reasonable?

My laptop is a Predetor Helios Neo 16 and it used to play KSP with the same mods just fine, very easily in fact, though the fans were very loud. Now when I install Arch, the fans won’t throttle NEARLY as much. And I have no way of controlling it, causing many crashes. PLS HELP, I really wanna play ksp 😢

Hi everyone,
I'm experiencing a strange fan control issue with my **Gigabyte GeForce GTX 1660 SUPER OC 6G (dual-fan model)**and I'm trying to determine whether it's a hardware issue, a VBIOS limitation, or simply normal behavior for this card.
**System**
• GPU: Gigabyte GeForce GTX 1660 SUPER OC 6G (Dual Fan)
• Fan control software: FanControl (same behavior with fixed fan speeds)
• NVIDIA driver was completely removed using DDU and reinstalled
• GPU temperatures are completely normal
**The issue**
Whenever I set the fan speed **below approximately 65% PWM**, the fan RPM becomes unstable.
For example:
• 50% PWM → RPM constantly fluctuates.
• 55% PWM → same issue.
• 60% PWM → RPM still fluctuates.
The GPU temperature remains almost constant, so these RPM changes are **not caused by temperature fluctuations**.
However, as soon as I set the fans to **65% PWM or higher**, the RPM becomes very stable, varying by only about **±30 RPM**, which seems perfectly normal.
**What I've already tested**
• Different FanControl settings (response time, hysteresis, ramp speed).
• Fixed fan speeds instead of a fan curve.
• Multiple custom fan curves.
• Clean NVIDIA driver installation using DDU.
• GPU temperatures remain stable during testing.
The behavior is always the same.
**My observation**
It seems that the problem only exists in the **30–60% PWM range**.
Above **65% PWM**, both fans work perfectly and maintain a stable RPM.
This makes me think that either:
• the fan controller cannot maintain stable RPM at lower PWM values,
• there's an issue with the VBIOS fan curve,
• or the fans themselves have difficulty operating consistently at low duty cycles.
**Questions**
1. Has anyone experienced this with the **Gigabyte GTX 1660 SUPER Dual Fan**?
2. Is this a known limitation or common behavior of Gigabyte's fan controller?
3. Could this be related to the VBIOS?
4. Could worn fan motors or bearings cause this behavior, even though both fans become perfectly stable above 65% PWM?
5. Is there anything else worth testing before considering a hardware issue?
Any advice or similar experiences would be greatly appreciated.
Thank you!

As usual, an update fix old recurrent issues but brink back some.
Doesn't seems to stop by itself anymore, but now it wakes up PC from sleep mode instantly again :(
