adjusting a fan curve for fractal torrent compact

[CitizenBane]

hello i have a new pc and the default fan curve i got with my motherboard felt like i have a helicopter base at home, i've manually tinkered it and seen some improvments but i belive it's most likely not optimal (see picture attached)

 

case is fractal torrent compact as mentioned in the title

cpu cooler is thermalright phantom spirit 120

cpu is ryzen 7800x3d

 

at the current fan curve i'm at mid-high sixties when playing the finals on max (runs on unreal engine 5). there is audible noise but not too much. i should mention that it's mostly the case that causes noise and not the cpu cooler the cpu cooler makes some minor noise at high levels the case however is insanely loud to the point i might regret purchasing it

 

appreciate any help

instead of trying to micro manage your curves make them smooth/gradual or just a straight diagonal line. it doesn't work like you obviously think it does... make it something simple like this

 

 

 

note: i have 5800x3D and my fans never do this fast rev up/down thing

 

 

ps: this in particular is the worst thing you can do to any fancurve

 

 

its the opposite of smooth or gradual basically you're forcing your fans to go as erratic as possible,  they may never rest  lol

Your fan curve is too linear. keep your fans running below %30 until your case ambient temperature is 40-50c then ram it up agressively. I personally have mines ramp up to max at 65c and my tmax inside the case is 55c.

the part you mentioned in my fan curve never gets put into use anyways my cpu temp is never that low even when idle, as for your fan curve my case fans get very very loud after 75% capacity which is the core issue

i can change the fans to 30% at 40-50 but as mentioned above the problem is when case fans go above 75%

Cases don't make noise. Fans and pumps can. I guess that's what you mean since you're asking for fan curve advice...?

 

My guess is that the original curves were optimized for top performance,  which means the fans are noisy. If it's too loud for you, then the goal you should have is to keep the noise to an acceptable level until the CPU is approaching thermal overload. Since the PS120 is such a good cooler, that should be enough for your CPU.

 

If you want it to stay quiet for as long a possible, just do a flat line till shortly before the throttling temp, then shoot it up fast.

 

If you want the fans to try to keep up but the noise to not seem as noticeable then have a gradually increasing curve instead.

yeah i meant the fan cases, after 75% usage they're loud

 

as for the curves you suggested, i'd appreciate an image of a good curve so i can repeat it in my program. i had the default gigabyte profiles and they were all horrible including the silent one. mostly because it applies the same curve to all fans meaning the case fans have the same curve as the cpu fan

A fan curve is a personal thing. Me, I use Turbo preset, and that won't work for you. What curve you use is determined by performance balanced with noise. Noise at the level you are experiencing is a non-issue for me, which is why I gave you the suggestions that I did. The other problem is that noise you hear is dependent on the case, the build, the fans, where you place the case, etc. So, really, you have to play with it. Either a flat line, a gradual slope, or a hybrid. Sorry.

the pc is under my table close to me

as mentioned the cpu cooler doesn't make too much noise even on max

case fans are loud over 75% capacity

during gaming in the finals im at 65-70 with the curve i posted in the first post and low level of noise

i'm asking if i can improve performance, sound level or reduce the material wear of the fans with a better curve

Yes, yes and yes.
Undervolt the CPU, which will cool it off, but at a slight performance cost, so you can also up the clockspeed a bit.

Or, use more aggressive fan curves for the case and cooler, which will force the temperature down, resulting in better performance.

The former will allow you to have your fans last longer. Really, though, unless you're buying really crappy fans, they should last a few years and you should be more concerned with temperatures than fans.

is 65~70 not good enough for a game such as the finals? again i can make the curve more aggressive but then there's sound in my room

It is fine, of course. You were asking how to decrease the noise, so I've given you options to consider. I hope that helps.
