Hi,

B450 PRO4 doesn't have fan step up and down option in fan control section. I have latest bios 3.90.

It is a good feature for keeping case fans RPM's constant when cpu temp spikes. Board has Nuvoton NCT6779 chip so i think it can be added to bios ?

Does other B450 Asrock boards have this option in bios ?

Thanks.

Hi,

hmm I never heard of this feature but it sounds good.

My case fans always ramp up and then down, just browsing and doing basic tasks. Sure, I can set up the case fans to monitor motherboard temperature, but the motherboard temperature like never changes, so it's always constant and doesn't ramp up when CPU gets hotter.

Thanks for reply,

My goal is to make fans faster when cpu gets hot so better air flow inside the case ,when gaming for example.

Also i want to make them quiet when browsing or etc.. But ryzen temp can suddenly make a peak for about 0.5 -1 second. If we had this step-up-down option in bios it could be very useful.

Hope forum admins from ASRock can reply.

Was just curious because I have got a Raven Bridge CPU and was wondering about updating the BIOS to 3.90 after ASRock advise not to do so. You're fine with a Matisse.

Not sure about your issue though. Mine seems to work as it should with stock settings, although the ramp down does take a while, but not so long as to be a concern or annoying.

I have Ryzen 5 2400G, so maybe the APU is the difference?

I have Ryzen 5 2600, mine idles at 45°C, when doing basic things it's 49°C-51°C, but when opening a program for example, the CPU temp spikes shortly to 60°C, so I hear case fans spike too.

Hmm... maybe I could set up the case fans to run faster when cpu hits 65°C or 70°C.

That seems quite high.

I'm currently at 28.5°C whilst transferring large amounts of data to a backup drive - APU at 27.5

Idling - looking at 25°C

Wow 25 in idle? Where you live? A tent in Alaska? :-)

I own a 3600 and it idles around 40. The moment I only start a program, it's movin' up to between 50 and 60 depending on the prog.

It's aircooled with a BeQuiet DarkRock which is running on idle around 370 upm, case fan at 800 upm.

Alaska! Close...Manchester, UK

Just have stock cooler, two case fans. Case is a full ATX though which may allow for more airflow.

I don't know.
