GPU, CPU, and Case Fan settings in Fan Control: Better to set them at a series of flat limits or curve?

reddit.com › r › buildapc › comments › 13ngohy › gpu_cpu_and_case_fan_settings_in_fan_control

Cooler usually means longer performance life. I’d set fans to an aggressive curve as they are much cheaper to replace than other parts. I normally do somewhere around 30% all the time, going on a straight curve to 100% at 75. Also that’s a lot of intakes for a single out take. IMO the best way to achieve longevity is a backup battery system and ensuring your pc is as dust free as possible, and you definitely have positive air pressure lol.

r/buildapc on Reddit: GPU, CPU, and Case Fan settings in Fan Control: Better to set them at a series of flat limits or curve?

May 21, 2023 -

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.

Just flat, 50 or 75% fan speed around the clock
Flat plateaus (ex: 33% power between 0 and 45C, 66% power between 46 and 60C, 100% power at 75C and above)
A straight line "curve from 0 to 100% with a single minimum and max temp
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.

CPU cooler : Noctua NH-D15
3 x Arctic PWM PST 140mm (daisy-chained) as Front intake
1 x Arctic PWM PST 140mm as Back exhaust
1 x Arctic PWM PST 140mm as Top (back) exhaust
Case : NZXT H5 Flow
CPU : Ryzen 7800x3D

This works like a charm. As you can see, idling in Windows the fans barely spin and the CPU sits at a cool 40°C. No noise!

I set the curves so that the case fans ramp up to max 60%, and the CPU fans to 100%. It does get a little bit more noisy then but still very bearable. CPU temp doesn't go beyond 80°C even when running things like Cinebench, OCCT, etc.

I love this build and I love Fan Control!

Watch this video from Jayztwocents. https://www.youtube.com/watch?v=uDPKVKBMQU8&t=468s You should use "Mix" so you case fans are not just ramping up based on a single sensor. Second thing is, lower your step down percentages from default 8% to something like 3% as Jay says. The reason is it takes time to exhaust heat and if you were to suddenly slow down the fan speeds there is residual heat causing the sensors to think it's hot again and thus making it ramp up unnecessarily. You shouldn't worry about fans being too fast. You should be cooling your components as best as possible to maintain their longevity, everything else doesn't matter. Noise is the only thing if it's always running loud, but that would be due to cpu/gpu maxing out too often and that just means you need an upgrade. Based on your specs, you shouldn't be running hot that often.

So Im new to the whole Fan Control app and I was wondering your guys suggestions on how to set the fans? Right now I have them paired to the CPUs sensor ( case fans and Ram fan ). Fan Control was recently able to control AMD GPUs ( 7900xtx ) and I was wondering how you guys control that.

These are the fans that I have installed.

Rear exhaust fan
Two front intake fans
Ram Fan

Do I need to set multiple points on the graph? Or will it ride the graph upward along that path set by those two points?
Should I have the case fans ramp up based off of another sensor/ the Hot Spot on the GPU? Maybe have the case fans tied directly to the Hot Spot since thats the most internal heat created?
Any other suggestions?

-You only need the 2 points if that's how you want to do it. -I have 2 temp sources, CPU and GPU (I don't usually look at hotspot) As far as suggestions go, I always use a time average on my CPU temp to keep temp spikes from making my fans go crazy for a second or 2 every once in a while. I know the temp can spike high when loading a webpage or something but its not for long so I don't need my fans at like 80% for 2 seconds, lol. I've never used a RAM fan and I've never really cared to monitor my RAM temp, so I don't have any suggestions for that in particular, but I think I would make my RAM fan the same as my CPU fan speed. Case fans are a different story. I make a graph for CPU temp, one for GPU temp and a card (I forgot the name of it, Mix?) that allows you to pick the max from those other 2 graphs and set my case fans to that, so no matter which component is hot, the fan speeds will ramp accordingly. Jay has a nice video over how he does it: (kind of an old video, I'm sure there are newer/better ones out there now, but this was the first one I saw that showcased this software) https://www.youtube.com/watch?v=uDPKVKBMQU8 And the FanControl manual is nice because it's a quick reference to what you can do with the software: https://getfancontrol.com/docs/

slow enough that the noise doesn't bother you and fast enough that the system doesn't over heat

The higher the RPM, the louder a fan is going to get. Set the intake and exhaust fans at a static %, or assign a curve that ramps up if temperatures hit a specific level. For example, my case fan curves are: 60 deg 45%, 80 deg 100%, i.e. the fans run at 45% until 60 degrees is reached, then it will increase. The only fan that should be scaling off CPU temperatures would be the radiator / cooler fan. Otherwise, you'll have multiple fans ramping up, ramping down, creating turbulence in your case.

r/Noctua on Reddit: What is your favorite way to setup fan control? (Intake vs Exhaust, etc)

August 6, 2025 -

First time building my own PC - I'm going to run 3 x intake and 1 x exhaust (140mm G2's), as well as a D15 G2 CPU cooler.

Any tips on where to connect all the PWM fans, and how to control the 3 x intake and 1 x exhaust fans?

I'm thinking:

3 x intake = control these under it's own curve (CHA_FAN1, CHA_FAN2, CHA_FAN3)
1 x exhaust = control under it's own curve (CHA_FAN4)
D15 G2 fans (2) = control under it's own curve (CPU_FAN, CPU_OPT)

Run with Fan Control program? (Not sure which is best in 2025).

Here's what I'm working with:

2 x NF-A14x25 G2 PWM SX2-PP
1 x NH-D15 G2
1 x Fractal Define 7 XL Case (comes with Nexus+ 2 Fan Hub = 3 x PWM fan hubs, 6 x 3-pin fan hubs)
1 x Asus ProArt X870E Creator Wifi Motherboard (8 x PWM fan hubs)
1 x Gigabyte GeForce 5060 Ti 16GB Gaming
1 x SeaSonic GX-1000 PSU

Goals:

Quietest performance at idle / low loads
I'm OK with it being louder under higher loads (video editing / AI tasks / etc)

Thank you in advance for any help

3 x intake = control these under it's own curve (CHA_FAN1, CHA_FAN2, CHA_FAN3) Just use a splitter cable and connect the 3 fans to the same header. I use FanControl to adjust the fan curves, much better than using BIOS imo, you have a lot more control and don't lose your curves when BIOS is updated. My fan curve looks like this for quietest operation:

I've the Fractal Define 7 with the same Noctua fans as you but the Fractal Define fans are used as inlets for the front fans to reduce turbulence noise at higher RPM, as you know from earlier posts. The three fronts Nocuta fans are on the same fan header, the two rear exhaust are on their own, and the two CPU fans on the same fan header as well. By having fans on the same header you take advantage the RPM offsets for your fans. Just check your motherboard manual to see if the fan headers have enough output (my Asrock X870E Nova have). The fan curves is setup using the Asrock motherboard utility for ease but when finished I use BIOS only for controlling the fans. I don't want a running utility for that. https://www.reddit.com/r/FractalDesign/comments/1kositm/fractal_design_define_7_with_fan_inlets/

I personally prefer stepped graphs as its the ramping of the fans that's more noticeable than static humming. I have set steps for my CPU where idle step is 0-50c -->20%, typical gaming load 50-80C--> 40% and finally ramp up from 80C for very high load cases. You can adjust the steps for your preference in temperature/noise.

I used Gemini. Gave it as much info as possible, fan mfg/model, fan orientation, cpu cooler, mother board, cpu, GPU mfg model, case. I gave it the config file (it can read it) and told it what fans were what. I told it what my noise vs performance preference is. Then provided it with a couple thermal results from cpu-z or something similar where I could start a log file, and ran some cpu and GPU intensive tests, indicating which test result was which. It will usually provide some tweaks, then I would run my tests again and provide it with those result. I ended up with a really nice fan curve profile which keeps it cool but quiet.

So i want to create a fancurve for my cpu. My cpu cooler and case fans are too loud and it annoys me. I have a ryzen 7 5700x3d and a Thermalright Phantom Spirit 120 SE ARGB cooler.

First off, i don''t know what speeds i should put at what temperatures. I want my cpu to be cool but not that the fans are so hot. Also, what do case fans use as the temperature source? Should i just use my cpu temps as a reference? Lastly, what do these two features in the picture do and what is the best settings for therm? Thank you in advance!

My 9800x3d doesn't really ever drop below 40C, so I set the minimum fan speed at 35% for 40C. 35% on my fan is around 550rpm, which is mostly silent. Here's what my fan curve looks like ( https://imgur.com/a/lcLlt4t ). I like to keep the fan spinning slowly as long as possible and ramp up as needed if it's getting hot, which I consider to be above 60C. 40C = 35% 50C = 40% 60C = 50% 70C = 75% 80C = 100% Start with something similar to what I have above, and adjust it from there to your preferences. Keep in mind my CPU fan spins at 1500 rpm when at 100%. If your fan is faster or slower, you may need to adjust.

I'll point you to a previous post here: https://www.reddit.com/r/FanControl/comments/1iqjjxr/comment/mdsa9ww/?context=3 How you configure your fans is going to entirely depend on your hardware, your coolers and fans, your case, your ambient temperature, and what noise:performance you are comfortable with. What speeds to use at what temperatures really relies on all of the above info, but there's a few things to keep in mind that might get you started: Set the 100% speed of your fan curve to the highest temperature that you are comfortable with your CPU hitting. Set the 0% speed of your fan curve to a few degrees below whatever your normal idle is. Understand that, in most cases, you'll want to induce positive air pressure in your case to prevent dust buildup. After that, it's just a matter of testing under typical loads that you'll experience. While testing and watching your temperatures, if you feel like your CPU is running cool enough and you'd instead prefer your fans to be quieter, adjust the curves down for that given temperature. If you feel your temperatures are too high for a given noise level, adjust the curves up. Rinse and repeat. And since nobody answered your question about the two settings you circled... they have to deal with hysteresis, which is the delay in which an output is realized from a given input. When it comes to fans, hysteresis is all about avoiding sudden changes in fan speed (which cause more noticeable and unpleasant fan noise) due to transient temperature spikes which are not uncommon. The Hysteresis setting determines the degree (temp) change required before your fan curve will take effect and change your fan speed. The Response Time setting determines the time over which the Hysteresis degree change must exceed before your fan curve will take effect and change your fan speed. For example, assuming you're monitoring your CPU temperature, with the default of 2H and 2RT, your fan curve will not change at all if your CPU temperature goes from 40-41. Nor will it change it your CPU temperature goes from 40-45 for 1 second, then goes back down to 40 afterwards. If you change your settings to 5H and 1RT, your fan curve will not change at all if your CPU temperature goes from 40-44. However, if your CPU temperature goes from 40-45 for 1 second, it will change (to whatever your curve is set to). If your change your settings to 1H and 10RT, your fan curve will not change until your CPU temperature exceeds 1 degree change for over 10 seconds. Most of my curves are set to the default 2H and 2RT, but my rear and bottom exhaust fans are set to 2H and 5RT in order to delay any fan changes as a result of transient temperature swings.
