Hey all.
Quick question about fan control on the B450 boards. When using Tctl as temperature source, won't the fans annoyingly keep ramping up/down rapidly to match spiking Tctl temperatures? Or is there a hysteresis or step up/down feature I'm just not seeing?

i think all asrock boards (am4) use the same fan controlls? the ramp up is very noticeable, i try to set the temps beyond the spikes. but this is still a compromise. and still very noticeable with the quick fan speed changes. i think we only can set the curve. no step up hor hysteresis. i wonder whats up with the sensor in the socket. why is it disabled on almost all asrock boards? is it broken fom the factory? or maybe its just the core temp + smoothing?

My B450M Pro4 has many issues: - Fan control does not work with MB sensor. - Fan speed changes rapidly when using CPU sensor. - Strange counts of the other sensors (VRM Mos and VSoC very high and do not vary). - Coil whine of the MB while heavy load on GPU. I read the sensors with HW-Info (latest version). This is very annoying. I replaced a Gigabyte GA-AB350, because I wanted to control 5 fans separately. The Gigabyte MB had only 3 fan headers, but the fan control worked very nice. Again, very annoying. Miepel PS: Please excuse my poor English. |

TCtl seems to be the only value, that works with the fan control. So I've connected all fans to TCtl.
There is an option for temperature hysteresis (AMD CBS/MBIO/Fan control). It is possible to set it between 0 and 255, but I didn't recognized any difference. |

ASRock B450 Pro 4 here.
Same Problem. Very glad to find this thread. Was ready to send the Board to RMA and buy anoter one. I think there are many users who regognize these problems and than try another Manufacturer. Asrock should fix it. Monitor CPU has no effect. tried Bios 1.4 and 1.5. till today I cant confirm that monitor MB works. |
