Thank you

One and a half years later and this issue is still not solved. I just installed EVGA Flow Control for the first time to create a custom fan curve for the EVGA water cooler I have bought and I ran into this issue within the first 10 seconds. The custom fan curve in EVGA Flow Control is pretty much useless because of this bug. Is this the typical level of support EVGA provides for its products? 

Not typical but this one is having this specific software issue.  I reckon there aren't many users who care or run workloads that lead to high temperatures for long runs.

I've sent support another query in-relation to this.
A new literally told them, EVGA Flow Control software is like legacy BIOS compared to NXZT and Corsairs CLC software. EVGA need to lift their game. Have been a long time advocate of EVGA. If nothing changes, I will be taking my money elsewhere.
 
My new 3800X build temps at stock, fluctuates between 28c-44c due to POA and Auto OC. The RPM on the fans have spaz attacks, ramping up and down constantly.
The limit needs to be adjustable upto 80c.

3 Years later, we still have to deal with this BS. When are you going to fix this EVGA?

The more and more I try to work with this cooler the more I'm disappointed. Wish Lian Li Galahad 360 White would come in stock, cause I'd really like to move on from this cooler. It's so loud!

I just discovered this issue myself. There is absolutely no reason to disallow control of the 100% fan speed curve target. The bottom one is also locked, which actually makes sense (to prevent overheating of the CPU).

Unrelated to this issue, I already had to majorly jump through hoops due to this software (regarding starting Flow Control with windows without the UAC yes / no prompt every time). So it's not just this bug (extremely myopic feature?) that is significantly problematic.

The overall UI and functionality of the software reminds me of software from the early 2000's. Clearly EVGA Flow Control is abandonware. 

Have a look this post #10 

so I guess the issue still persist in 2021? wow

Was fighting with this for a while today before I decided to read the actual text inside the curve windows... In case anyone looks this thread up. When you open the curve button two windows pop up - one with a check box for FAN CURVE FOR CPU and the other with FAN CURVE for Coolant... Make sure you're using the checkbox for the coolant curve. There's no reason to ever peg your fans to the CPU temp, since that will just make the fans bounce around since they don't cool the CPU directly they cool the coolant.
 
If you think about this it makes perfect sense... running the fans at 100% when the CPU is at 95C won't increase cooling at the CPU/cooler interface one tiny bit... it will increase airflow over the coolant, but since the coolant is typically much closer to room temperature and changes rather slowly over time because of the heat capacitance of water, your fans will be bouncing up and down based on CPU activity while your coolant is probably not even changing temps. If your coolant is only a little bit above room temperature running the fans at 100% does basically nothing, so realistically there's no reason to ever peg the fans to the CPU temp, and instead they need to be pegged to the coolant temp. If you're running your pump at 100% flow... which it pretty much defaults to... then there's no additional CPU cooling available no matter how fast the fans run unless the coolant is substantially above room temperature.
 
So while it's stupid that the fan control curve from the CPU is limited to 60C it doesn't really matter... since the fan control should basically never be dictated by CPU temp... and your coolant should basically never hit 60C so it is an appropriate max fan speed step in the context of coolant temp.
 
Tl;Dr set the check box in FAN Control for Coolant, and ignore the FAN CURVE for CPU window, and everything makes sense.
