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. Answer from pagemap1 on reddit.com

A control (fan) can either be set manually, or through a fan curve. To assign a fan curve to a control, use the "curve" dropdown menu on the control card and select the desired curve.

r/FanControl on Reddit: How do i create a good fancurve
March 13, 2025 -
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!

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.
Does anyone know how to use "Fan Control"? Also, I don't know what's killing my PC's gaming performance.

Fan Curve/Setup Suggestions?
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. More on reddit.com

April 19, 2024 - Implementation: I am now trying to find out from which value in % of the maximum speed the fan starts – in FanControl this would be possible with the manual control. I set the first fan to 0% and wait until it stops. It is possible that this standstill does not happen, because there are also fans that do not support the 0RPM mode at all – silent operation would not be possible with these.

Monitor your temperatures with attention, it is very important to understand how temperature works.
Add a linear curve and try these settings:
Don't forget to select your CPU package as a temperature source and select the graph on the CPU temperature. Ensure that "Manual Control" is turned off.
You can add the tray icon on the left menu to help you monitor the temperature.

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.

Question - What fan curves should I set up for this system? | Tom's Hardware Forum
May 19, 2024 - EDIT: Never mind that, The CPU fans are in fact super quiet even at 100%. I used manual fan control to check. For some reason they default to about 20% speed at the lower end of the curve while the case fans all start off at higher speeds. I can change that to 60% speed without it being noisy.
