Hello forum !!! ^_^

I have build a new system and put 4 pwm raijintek fans in there to get a good airflow!
My problem is that is seems there is no real control over the chassis fans, i have installed them of course on the pwm motherboard headers,
and i tried from the uefi bios to make a nice curve with them being idle at start and start spinning after cpu reaches 60C but that wont happen
fans spin all the time and their speed from HWmonitor :
---Fan 1 boreas 140m pc idle speed (should be 0) 390 rpm,
rpm range from Raijintek webstite 600~1000 R.P.M. [PWM controlled]
---Fan 2 Aeolus 140m pc idle speed (should be 0) 770 rpm,
rpm range from Raijintek webstite 650~1400 R.P.M. [PWM controlled]
---Fan 3 Aeulos 120m pc idle speed (should be 0) 390 rpm,
rpm range from Raijintek webstite 400~1400 R.P.M. [PWM controlled]
---Fan 4 boreas 140m pc idle speed (should be 0) 500 rpm,
rpm range from Raijintek webstite 600~1000 R.P.M. [PWM controlled]
Also cpu fan is a Boreas 140m , which also spins constantly, starting at 470 rpm, besides having him start only when cpu is above 60c (like a gpu)
Cpu temps are really low sitting at 30-40 degrees at idle and 60C under prime stress test! that's when all the fans are spinning at the rpm range shown above.
I've tried 3 methods to work this out,
- first making fan curves at uefi bios Fantastic setup, didnt not work at all.... all fans are spinning
- second i tried the F-stream tuning utility , which is like uefi bios , but on windows... and did absolutely nothing at all..
- third option was speedfan which i know how to setup from previous pc , but somehow wasnt supported by the asrock h170 perfomance fatal1ty hyper motherboard that i've got. Speedfan could not give me acces to pwm headers and didnt have that option "software controlled" neither the "manual" option worked since even when i was tuning fans to 0% spin , nothing would change , except! the gpu fans... :/ which i already control through gpu software...
I dont want to use an external pwm controller, since i want the fans to speed up automatically when temperature is rising! having the fans stop at idle whould make the pc so much quieter, basically silent! , gpu and psu have that mode and at idle their fans dont turn at all, but all the pwm headers of the motherboard make my fans spin all the time ! making the pc non silent , i wish there is another way to control fans and make them stop! since my cpu G3900 can be passively cooled at idle with the enormously huge Raijintek Tisis cooler....

Hope you have some ideas so i can try to make fans turn off!!! thanks for reading !!!
