I only have a Ryzen 3600 in right now but once I upgrade to 5900x (hopefully if I can get one) then I will probably have to bump that max CPU fan value a little bit, but even at 70-80% it's not very loud relative to ambient sound and the rest of the system.Īnyway, everyone's specifics will be different, but I was just so happy to get a software option for controlling fans based on GPU temp. I've got my AIO (Arctic Liquid Freezer 2 240mm) at flat 30% up to 60C (idle temps are 35-40C), and then curves up to 50% at about 70C, where it tops out at max temperature under load with Prime95 torture test. I also use Argus Monitor to control CPU fan curve, and again it's super useful to manually test different PWM values to see what sound level you accept for the temperatures you want to hit. I am using a Lian Li Lancool 2 Mesh Case.
GPU idles at about 41-45C in this setup, and max temp is about 70C under full gaming load at 400w board power draw. This let me set my 3 onboard GPU fans with the EVGA Precision X1 Software to remain off, until GPU hits 50C, then that fan curve goes up to only 40% at 70C I keep my case intake and exhaust fans at a flat 40% (I have six be Quiet! 120mm PWM high-speed fans) until GPU temp hits 50C, then those case fans curve up to 50% when GPU is at 70C. You can also manually set PWM % on a slider to test how high you want to push your fans to stay quiet with your desired temperatures. It even has options for averaging temp from a source over time (like a 10 second average of GPU temp or CPU temp) to prevent frequent ramp up/down and other advanced customizations. I have to assume this is not a unique thing for my specific card. If anyone has more info on that let me know please.īut anyway that's a moot point because Argus Monitor can have a custom fan curve based on basically any temperature sensor it has access to in your system, including GPU temperatures, at least with my GPU. Again, I think it's this "load" sensing issue, and I don't know why the GPU PWM headers are set up that way compared to mobo PWM headers. Motherboard PWM headers work fine with the hubs. I even tried a splitter with the main PWM fan "master" connection being a single fan, and the "slave" connection being the fan hub connector, but it still did not send PWM info to the hub - unfortunately the hub fans ran at full speed while the single PWM fan powered by GPU PWM header was being read and controlled correctly. But a PWM hub does not draw power from the GPU header, it has an external power source (SATA or Molex connector). Plugging in a single PWM fan or two PWM fans on a "Y" splitter cable work fine, since they are both being powered by the header. I don't understand it completely, but apparently the GPU PWN fan header requires sensing a power "load" to send correct PWM information to the fans. Unfortunately, PWM hubs don't work on the GPU fan header. So it makes sense for case fans to be tied to GPU temp more than anything else. I currently pull 400watts GPU board power draw with it OC'd. Since my CPU has an AIO radiator that is cooled by fresh air intake, the inside of my case temps really mainly affect my GPU once that ramps up under gaming load. I didn't think controlling GPU temp was possible outside of GPU-specific software, and I bought a 3080 FTW3 Ultra with hopes of using its PWM fan header connected to a PWM fan hub to control most of my intake/exhaust fans based on GPU temperature.
I paid $10 for the personal use license after finding that it did exactly what I wanted it to. It does a lot of other things but this is why I tried it.
