What fan curve should I use?

[Bandooka]

Not necessarily a new build as I have had the PC for a while, but it always sounds like a jet in game

 

I was wondering if anyone had any suggestions for what fan curve to use

 

my current specs are:

i7-13700K

4070Ti

ASUS TUF Z790-PLUS WIFI

5000D Airflow

10 x iCUE link fans (three front and three side are intake, top three and back one are exhaust)

iCUE link H150i

(mounted at the top of my case with my fans blowing upwards into it)

i set it for as hi as i like it at idle that's the base line if its 40% then start ramping at say 60c say 60% 70c 70% 80c 80% or 100% something like that probably have to set a gpu fan curve in the gpu software.

What temps is the CPU?

I always set my case fans as fast as I can without them being audible, that has worked really well over the years.

For GPU, your GPU might have a quiet BIOS switch that you can enable.  It will give you a bit higher temps but lower noise levels.

 

I did that on my RTX 4080 and I went from 60c to 68c but the noise levels dropped A LOT.

A flat one until the danger zone. Corsair AIO so don't they have water temp sensors built in means the rad fans can trigger off that? Radiator fans are meant to cool the water, not the CPU. Therefore they don't need to be ramping up and down with erratic CPU temperature. The case fans.. I mean. Me personally my whole case is set to a static 40% PWM until the CPU hits 85c which is almost never unless I do something heavily multicore. At that point they ramp to 60% PWM. I don't know where you have everything plugged in and controlled from so that'll be up to you to determine.

 

7800x3D/4090 all air cooled in a Torrent and I can't hear my system in normal operation / gaming over the ambient sound.

CPU temps are around 70°C under load, so temps are fine. I’ve adjusted to iCUE Link quiet curve and it’s on average around 300rpm slower so it’s decreased the volume a bit 

 

Connected to the iCUE link hub, both the PSU and The motherboard

I second that. I use that for my GPU where I let it go up to a flat part that it should never go past and only at the dangerous temps I wramp the fans high. Same for the CPU, which I set to 50% all the way until 90°C, where I send it pretty hard and close to 100°C I send it to 100%. The case fans spin up based on the GPU temperature and they have a very slow wramp-down (0.5%/s) to give everything time to cool down since the GPU jumps up&down by like 15°C when switching between idle and being used. It jumps up 15°C when it's put under load and only climbs another 7-9 degrees, then when the load goes away, it drops 15°C straight away and slowly goes down by the same 7-9°C

Alright, so would you say something like this curve would be safe to use?

Safety isn't part of the equation, and I can't tell you if that's acceptable because I don't know how it works with your parts in your case with your fans and with your ambient temperature. If it works for you, then its good to go.

Yeah, just tried it, PC got *very* hot *very* quick in game, definitely not having the fans that low
