Hi guys,

I've just bought a set of be quiet! Pure Wings 2 PWM fans and I've already set custom curves for them, but since Ryzen CPUs tend to have 10+ °C temp spikes every couple of minutes, I've been having all my fans speed up for ~5 seconds and then slow back down, which is really annoying. I have an MSI B450 Tomahawk MAX motherboard with the latest stable BIOS, and the only fan speed up delay options are 0.1s, 0.2s, 0.3s and 0.7s. Is there any option or workaround to set these delays around 2-3-5 seconds instead of these fractions?

Thanks!

I use this when BIOS has no fan curve options.


You can set fan curves, response times and hysteresis etc. tho I think you should disable fan curve in the BIOS if you use this software, temporarily at least, just so the settings do not interfere with each other.

Can you set the hysteresis in the BIOS higher?

Thanks, I'll give it a try.

There's no such option unfortunately.
