How to set-up a good Fan Hystersis in Bios?

[simon_leuener]

Hello Everyone

What is the best way to set-up a good Fan Hysteresis in Bios.
Normlly u can set 0.5-2.0 Sec, so the Fans dont go up in speed as soon u open
a program or browser due to a lil peak in power.

I didnt find a button in Bios for it.

Im not good in programming own Fan-curves. Aka idk how.

Maybe someone have an idea how to do it or how they done it.

Thank u and have a good Saturday community 😮

Haven't done fans in my Bios for a year and can't remember specifics. Sure that'd depend on the board too. I started using an app to do my fans 4-5 months ago. Link to the DL and a Youtube tutorial that should help if you want to try it out

The software recommended by Drayco31 is supposed to be very good. I've never tried it myself but have seen it mentioned many times.

There is a difference between the rate at which fans change their speed and hysteresis.

So for example, if I set a fan to turn on at 55C with hysteresis at 10C, then the fan would turn off at 45C. MSI Afterburner provides that feature and I find it useful to stop the GPU fan turning on and off so often. I also use Afterburner to reduce GPU power to just 25% when I'm using the desktop. That means that the fans rarely turn on and if they do, they cool it back to 45C which means they have to gradually climb all the way back to 55C before turning on again.

My BIOS does not offer hysteresis, but many software fan controls do. Armoury Crate offers fan rate controls, but again, not hysteresis.

Fairly certain AquaSuite software from Aquacomputer can serve the purpose you're seeking, if you are looking for a time delay or thermal delay and if you want to spend some time learning the software to that depth.

Yet it only works with Aquacomputer hardware, like the Aquaero 6, and Quadro fan/system controllers.

Aquacomputer forum in German or English can help you out. 🙂
