I think it allows you to create your own fan curve so you can determine how fast the fan spins as the temps increase over time, rather than letting AWCC do it automatically.  This works for the 2 internal fans (one intake at the bottom and the outtake at the top).  You can't control the GPU fan with AWCC, for that you need a separate software fan controller (like MSI Afterburner or there are others as well).  Or you can just let the GPU Bios manage the GPU fan automatically as it comes from the factory.

Ah okay so it manual adjusts the speed of the fans. Why I asked is because I would like my Top fan to manual run at like about 75% because this R11 as noted by many having the wrong radiator really get warm when running a 5.0 overclock. I think it would help running it manual instead of it throttling. 

Thanks for your input as I lack the experience and knowledge about the gaming world and machines and it’s hardware but have always wanted an Alienware machines,but I just want to learn how this  all works. I just started late as I’m in my mid 50’s.

thx

The AWCC custom fan solution is poorly implemented.

It's overly cumbersome for something as simple as a fan curve.

All they had to do is make it like Afterburner, or several similar utilities out there.

Instead they made these strange options called "offset" and "smooth line"

The smooth line is annoying to work with, so I used the offset option instead. From my own experiences with it it keeps the original auto curve, but offsets the requested fan speed across the curve with +%. That's what I found out when playing around with it.

Also, if you use Afterburner on an RTX 30 card you can now set 2 different fan curves, one for each fan on the video card. In the past it would be 1 curve for all fans. I played around with that option and run fan #1 9% slower than fan #2, as that provided the best balance between noise and tjunction temperatures on my 3080.

Yeah I did notice the 2 fan options for my 3090 in the new msi/af. I also played around with AWCC thermal offset too and like the Top fan running alittle higher then the front by at least 10%. Knowing now that the intel-10900K voltage delivery is not accurate @5.1-5.3 ghz. I settled at 4.9 ghz and running the thermal offset fans and it ran quit well and very good thermals. I don’t play AAA games so I really don’t need a big overclock the factory setting is okay. Also running this R11 on Balanced Thermals and High Performance mode does very well too with the offset. I’m always late on the screen so doing more research on this intel i9 10900k processor and watching  the big dogs testing and results when it first came out. I think once you find the right voltage and overclock it well run cooler and these fans won’t roar trying to hold 5.1ghz. A lot of people are undervolting it. Thanks for the info.

65 at 65c works for me
