Fan control software with separate curves per sensor?

My CPU is on a custom loop and doesn't need much in the way of fan speed to stay cool, even under load. Using Asus Armoury Crate I have the water temp as input, all fans set to idle at 32c and 100% at 40c. Regular desktop use doesn't see the fans really kick in, and even under full-core benchmarking I haven't seen water temp over 37c or fans over ~70%.

Day job is 3D modelling and rendering, for which this is a perfect setup. However, it's is a bit of a problem for gaming because if the CPU doesn't heat the water significantly the fans don't kick in and the GPU is stuck in a case full of increasingly hot air.

What I'm after is something that will allow me to define separate profiles for the water temp and GPU temp, where the fan speed is dictated by the highest. Armoury Crate will let me set both as input sources, but using the above profile would make the fans run at a constant 100% because the GPU is always over 40c.

Anyone know if such a thing exists?

Here's a mockup of what I'd expect Armoury Crate to look like with this sort of thing. T sensor (water) currently highest, but if the GPU were put to use that would quickly pass it and increase the fan speed accordingly.

Maybe I should send it to Asus?

Thanks. Hadn't considered the system temp option but will look into that. Have a feeling it will lag behind the more direct sensors though.

Guess my other option is to have the water temp control the radiator fans and the GPU as the source for the others. There's intake and exhaust for each so both should get air moving through.

You could also use physical sensor to measure air temperature inside case as one control source.

Definitely looks like it would do the trick and then some. Don't have any qualms about spending the cash, but not very keen on anything that requires a molex adapter in 2022 FFS.

Thanks for the suggestions all. Definitely looks like Argus would do it, and Fan Control seems worth checking out also.

At the moment I've got it configured as I suggested up thread. Radiator fans (in front, out top) controlled by water temp and the other chassis fans (in bottom, out back) via GPU temp. Seems to have been working fine like that, although I've just checked Armoury Crate and it's reset my curves for some reason. Justification for ditching it right there.
