How to Set Up Custom Fan Curves Using Fan Control v110?

Question

I recently downloaded the Fan Control v110 program and I wish to help augment my computer's cooling systems. How can I use the software to create customized fan curves?

Answer 1

With Fan Control v110, you can create custom curves by determining which temperature source you will use as a reference for the fan speed, for instance, the CPU or GPU. Next, you will draw fan curve graphs in the software by setting up points on the graph for the percentage of fan rotation at a specific temperature. Alternatively, you can also create mixed fan curves which are primarily based on multiple temperature sources and only the target temperature controls the fans. After creating the curves, assign them to the relevant fans in the program. Saving your configuration will ensure that your adjustments are not lost.

Just to clarify in case anyone gets confused. The "max" function on the "mix" curve selects the "max" fan percentage. NOT the max temperature. For example: if the GPU was 40C but you set it to spin fans at 100%... And the CPU was at 80C and you set it to run fans at 30%... The mix set to "max" would favor GPU and spin at 100% even though the GPU is cooler

this is EXACTLY how i want my case fans to act. have a curve for each hot component (gpu/cpu) and just take the highest value of those curves for the case fans. its brilliant!

I just got an used PC with a case fan that was revving up to over 2000 RPM all the time and I was like "why is that?". I followed your instructions and got the fan to run with the PC's temperature at resting rate of just below 1000 RPM. This is the case fan that was making this loud noise so I am so happy I found this software. Thank you and for the creator of the software for this!

Just want to say thanks to Jay for sharing this with us. It is difficult to control case temps with lacing software and this just made my day. Literally busy installing new non-rgb fans into my new case. Thanks dude.

I downloaded and set up the software immediately after watching this, with the explanation it was very quick and easy. I set my intake and exhaust fans to ramp up based on CPU and/or GPU temps, I dropped 5 Celsius off my GPU under 100% load! Very useful but of software, I'm sure with more tweaking I can drop my temps even more, donating $10 for sure, this shit is amazing!

Downloaded. Followed your tips, did a few of my own. Donated a few dollars. Need more devs like this. Seriously. Awesome stuff. My whole computer is now in sync instead of fighting for air.

This program does a great job of addressing the most obvious, yet somehow neglected, need in a gaming PC, ie. is controlling case fan speed based on GPU temp. This is why I have been using this program for about a year now. Almost spent about $75 more for a motherboard with a dedicated temp sensor input just to be able to do this.

You are so right, this guy deserves our support!  2.3M views, now 2 years later.  This was my third viewing.  I saw this before I had all of my parts.   I came back when I got to the stage of setting up fans and carefully followed along while I had the software open.  Now, I've had the PC built for about 2 weeks and went in to put a little more work into my curves.  I'm so happy with the way I was able to tune my fan speeds I just had to share how mine are running.  Originally, if the CPU and GPU were between 30 and 40 degrees, fans were at 50%, with a diagonal line down to 0% if temps dropped below 30.  On the other end, a diagonal line from %50 @40 degrees to 100% @80 degrees.  Today, I have a fan curve that pretty much runs a diagonal from 0% at @0 degrees to 100% @80 degrees on both CPU and GPU curves.  What's happening is actually interesting.  As I respond here looking at my Fan Control display, the CPU is 33 degrees and GPU is 36 degrees with fans at 29%.  Now if I do less than visit YouTube and comment, both CPU and GPU cool off enough to get to about 25% fan speed.  The AIO cooler fans don't shut off, but all the case fans completely stop.  The case fans are cheaper and don't run at such low rpms.  The AIO fans are from MSI and I would assume better quality allowing them to run at lower rpms.  If I sit and watch after my display times out, the fans kick on every 2-5 minutes for maybe 30 seconds.  The AIO pump and GPU fans are running at manufactures default speeds/curves.  So when I walk away, the GPU fans and AIO pump are keeping things cool enough case fans aren't needed.  So the case fans being less capable than the cooler fans is actually a good thing.  I hope I explained this well enough.

Argus Monitor has the same functionality. Studies show constant noise is less distracting than changing noise, even if louder, so make your curve “square” rather than smooth, so the fans step up and STAY at some rpm as temps rise and fall. To cool components after a load (slow ramp down) use ACTUAL temps from those components! Add them to the mix.
