[SOLVED] How do you setup a cpu fan curve?

For reference this is the post explaining what’s going on with my cpu & fans.

I’m stumped I looked around in BIOS & the manual

I realize i need to get a non stock cooler soon but in meantime for my own sanity I’d like to fix this.

Edit- I also set the min processor state to 20% is that ok?

i just read your manual and its the same as my MSI fan set up is in hardware monitor options in bios choose PWM control and it should provide you with a graph with degrees c / rpm or % of fan speed

i think the 3600x is a pwm cooler but it also states in manual that control depends on the cooler

You can set Minimum processor state to 0% if you want to, it doesn't really matter if it's under 50%, you loose or gain nothing.
Conversely, Maximum processor state at 99" also limits frequency to CPUs starting frequency without boost. Max frequency falls all the way until 50% and lower than that doesn't drop frequency further.
As for CPU cooler fan curve, it depends on actuall cooler but requires some balancing between speed and temperature as Ryzen's boost is directly dependent on core temperatures and above 70c it severely cuts boost frequency so with lower grade CPU coolers you have to make compromise between performance, temps and noise. Some MBs also have option to retard fan speed for some number of seconds so it cuts down on sudden speed bursts.

You’re right! It’s an PWM, thanks man going to head into bios again & see if I can do it.

Would putting that at 99 hurt anything ? Also thanks for the details, really helps me out!

If you mean max frequency,, it wouldn't hurt anything, quite opposite, it would work at lower voltage and ftemps but only up to base frequency but that also hurts performance. You can always do what I do, I set 2 different power plans, one for full performance (max 100%) and another one with about 50% at which there's enough performance for everyday mundane work like browsing or other less important things while 100% one for serious work or gaming.
AMD Ryzen Balanced for low and 1usmus power plan for high performance settings https://www.techpowerup.com/review/1usmus-custom-power-plan-for-ryzen-3000-zen-2-processors/
