So I posted this in the software forum but got no response so I'll try over here... Is there a way to change the upper limit for cpu temperature in flow control? I don't need my fans at maximum when the processor is at 60c. An overclocked 9th gen processor is over 60c all the time... The "coolant temp" fan curve is useless... I don't even know why they bothered with that.  Any help would be appreciated...

Welcome to the Forums

I'm not sure why your software settings are not working
 
You could plug the fans in to the MB directly - use the MB / CPU Temp to control them
 
What OS - with details ?
 
Which version of the software ?
 
We need & like Rig details

I thought about the motherboard route but that would require a splitter I'd need to pick up and tearing apart the top of my build (mini-ITX it's tight in there). The software is working fine, I believe, but I can't grab the upper limit "dot" on the fan curve at 60c. 
 
Flow Control Version 2.09
Windows 10 64bit
i5-9600K 4.9Ghz @ 1.34v (lost the silicon lottery)
Asus Z390i
G.Skill Trident RGB 2x8 3200mhz @ cl14
970 Evo Plus 500GB
CLC 240 w/ Noctua iPPC 3000 fans
EVGA RTX 2080 Blower
Seasonic Prime Ultra 750
WD Black 4TB
Cougar Vortex RGB Case Fans
NZXT H200i

Marked the dot with an arrow...

mini-ITX - that makes it tight for sure
 
Is the CLC Intake
 
What other fans are in the case ?  Blowing In or Out

Yes CLC is setup as intake with Cougar Fans and blower card setup as exhaust.  See pic.

lower right side of software "Fan Icon" word "Curve" is below it - click on it to open & set Custom Fan Curve

Yeah that's where the image came from.  The "custom fan curve" is locked at 60c to 100% fans. None of the points will allow me to set a fan speed lower than 100% past 60c.

I'm running ver 2.08 on my AIO Folding Rig in my signature
 
Did you try double clicking said marker ?
 
You Must make all lower changes, from left to right --> (you can not go below the previous set point)
(if I remember correctly - been months since I changed mine)
 
Might want to try 2.08
 
I do not see the picture in Post #4

I've tried everything to no avail.  Are you able to change the last set point in 2.08?
