HI @Rem0o With the addition of the subtract custom sensor, I would like to create a curve/graph based on Delta T (Water Temp - Ambient), however the lowest temperature available for the graph is 20°C - Might you be able to consider reducing that to 0°C in your next update? I would be looking to create a curve between 0°C and 15°C, for example. I was going to try this whilst I wait for the minimum temp on the Auto (Beta) option to be looked at - in fact this might be better/safer for me in any case. Once again, thanks again for your awesome efforts. It is quite amazing how this has grown from when you first started - it is absolutely unmatched, as far as I am concerned! Happy New Year to you!

The UI will let you set it, but even after saving, after restart it defaults to 70C when you go back it to check it. Idle temp 'sticks', but load temp does not.

HI @Rem0o - I have just downloaded your V99 Beta. The Auto (Beta) Curve looks very interesting indeed, and might just meet a use case I have been seeking for ages! I have set up a curve to monitor what it does in comparison to my existing curves I have set up, before 'pressing the button' and applying it to control a fan. Only thing is, I wanted to use it for Water Temperature Delta - I have set up a Custom Sensor that is (Water Temp - Ambient temp), and wanted to use that sensor as the source. Currently, it will not allow a load temp of less than 70°C - Is there any chance you could allow a lower load temp? Being a Delta between water and Ambient, I would like to set it at absolute max of 15°C, maybe even 12°C. Thanks.

This is great, thanks Remi. HWInfo plugin support has allowed me to give this a go, and potentially ditch another software package. Quick question - what is the best way to create a Fan curve based on a Delta Temp? E.g. Water Temp - Minus Ambient temp? I see you have recently added a mix sensor with Max/Min/Avg - could you add 'diff' to this, or is there a better way of doing it? Just about to click through the thread page by page to get up to speed - but any hints from anyone that knows this off the top of their head would be appreciated! (I think in reality, where I want to get to is a fan curve based on the difference between ambient and water temp, but mix it with a max curve on the water temp so if the water temp gets to a certain temp, that takes precedence over Delta T - but I'll work that out once I work out the Delta T control :-))

Ohh interesting. Could this ultimately be used with the Redistributable HWInfo Plugin and Shared memory function, to inject HWInfo sensor values into FanControl? I use that to display HWInfo sensor information in RainMeter and finally being able to use Fan Control instead of ArgusMonitor to control my fans (using the HW Monitor sensor inputs) would be great!

More information than the comprehensive setup videos contained in the massive first post you helpfully quoted?

Oooh. Could this be used for the Delta T scenario? Use the file to create a virtual sensor that equals Water Temp - Ambient Temp? Not sure how I would do that , but seems like a step in the right direction?

Yes, that's correct

Thanks for the reply - very much appreciated! Yes - exactly that, a curve based on Delta T°C between water and air. I hadn't really thought about the second question - my intiial thoughts are, yes, I would want the curve to react exactly the same. Reason being: I'm in the UK, so once I set a 'reference' the likelihood is that the ambient temperature isn't going to increase significantly enough that it becomes a real consideration. The capacity of my loop won't change significantly, only the relative performance/water temp in relation to the ambient temperature. If my loop can effectively dissipate xxxW of power, that won't change massively with an ambient temp change (not one I am likely to see anyway) so if I set my loop up properly, consider noise etc. and at 20°C ambient I am only able to maintain a Delta T of 15°C (so water temp of 35°C) at full load, if the ambient temp increases to 30°C it doesn't matter how much my fans are tearing away, the radiators aren't magic and will only ever be able to achieve a Delta T of 15°C, so it would be appropriate that max fan speed is tied to the delta still. Of course, the only time that may not be true is if the fan speed is setup as a compromise and I decide I can live with a 15°C Delta T under normal circumstances with quieter fans that still have further capacity. In this case I can see that if the ambient temp increased a sufficiently high amount I might tolerate a faster fan speed to reduce the Delta T for all the reasons you suggested. I would hope that is an outside case, and everything is a compormise right? In those circumstances I could setup a different profile so one for ambient <25C and one for >30C and select the appropriate one, or could I not use the recently added function to use a separate ambient curve to add an offset once a desired ambient is reached? That's a shame - I'll see if I can find out more. I think it is an extra sensor on the board - HWinfo64, Argus Monitor etc. see a number of temp sensors / fans under Nuvtron NCT6798D, and a further 6 or so (VRM, PCH, Aux Temp sensors) under a device called ASUS EC. I'm not running any extra Asus software, but you are right as far as I can see your software/the library does not see them

Looks great. What kind of temps do you get with that setup? Do you find the rear exhaust fan scavenges air from the top rad/fans affecting performance?

Hi there @Rem0o - great effort! Like many, I have been led here after finding that Speedfan does not work on my new machine, and other software such as Argus Monitor aren't quite there. I have read all the posts, and watched your videos, but I cannot work out if I can do what I want. With the mixed curves etc, it seems like there should be a way - but I just can't get my head around it! In essence, I would like to create a fan curve based on the difference between two sensors (ambient temp and water temp) - how would I do that? As an aside, I have an ASUS z390 Mobo with a NCT6798D. There are additional sensors that show up on other monitoring software from 'ASUS EC' - would these be exposed in your software? Thanks, Jason.
