fan What should my fan curves be?

iPlay_G · May 23, 2020

I have an i5-9600k and an RTX 2070 ROG Strix.
What should my fan curves be for my computer?
I have 3 Corsair LL120's on the front of my case, and a Hydro Series H75 for my CPU cooler (i know it's liquid but this is about fans)

I noticed this post talking about it, but it's also a few years old and for a 3 gen older CPU (air cooled) and 2-3 gen older GPU.

Thanks.

EDIT: This is what I have it at - think this is good?

it is entirely personal preference based on noise and how comfortable you are with the temps under load

I'm a fan of always running my fans at the fastest my ears will tolerate. So if you can tolerate 1500 RPM constantly then I'd run that.

I can tolerate some noise, but silent is better. Looks like my PC idles at 40C (i have ~10 tabs open, discord, and a few mobo/gpu configs open)

Only way to find what works is to test it. Some like linear curves, other use logaritmic. Or you could use steps. Its really personal. In short:

Linear = Straigth line starting from idle temp and lowest speed possible to highest speed you like and cut-off point where CPU is usually under load (for example 75C).
Logarithmic = Same start and end points, but curve steepens at the higher temp side. You picture is of logarithmic.
Steppes = Can be good if you have 3pin fans. Static fan speed until certain temp is reached and them speed jumps to next level.

I personally use linear and steppes at the moment. I just posted these in another thread:
