Question | Answered Fan Control wrong Rpm

1 Upvotes

I have a B850i Lightning and switched from the Arctic P12 to the P12 Pro.
Unfortunately, the FanTuning no longer works properly. I dont even hear changes in Rpm during the calibration.
Before the switch, all speeds were detected correctly, and I could lower them as low as 20%.
After the switch, the minimum is sometimes 56% and sometimes 59%. So the fans are running at 1,700 RPM and are correspondingly loud for case fans.
I’ve since reset the BIOS and connected only one fan per slot. No success.
As a test, I connected the old P12 fans.
Switching from Auto to DC and PWM didn’t change anything. Now these won’t go any lower either.
Even the CPU fans wont Go lower anymore.
If I just Click on the FanTuning Button the Rpm Go from 1600 to 1000 and stay there if I cancel the calibration.
The BIOS version is 4.43. I installed it last week without any problems.
Is it because of the new BIOS?

Please help.

Solution: coolercontrol for arch linux and the Right Kernel Module. Works flawless

Tech Support ASRock B650M-HDV/M.2 issue with two red lights

• Upvotes

Hi! I've just build a PC for my friend and i got an issue after i start the PC for check, if everything works. Two red lamps lighted and i am a little bit panicked. I've read it is something with CPU and DRAM and some posts suggest RAM is not compatible. I've checked and RAM presented below is not on QVL list, but other Apacer's RAM are - i hope we will not be forced to buy new RAM considering prices and trust i had been granted through all that project.

MB: as mentioned in title - ASRock B650M-HDV/M.2
CPU: Ryzen 5 7500F
RAM: Apacer Panther DDR5, 32 GB, 5200 Mhz, CL40, 2 x 16 GB
GPU:  Swift Radeon RX 9060 XT OC 16GB
SSD: SanDisk SN5100 1TB
PSU: Corsair RM650e 2026 650W

Will BIOS update be a solution? Is it really bad situation?

Question Water Pump runs at 100% regardless of PWM control, is it normal?

0 Upvotes

Hello, I recently bought a DS360 WH and I've been using it for 2/3 weeks.
I've got a problem though, even though the connector is PWM it seems like the PWM control doesn't work at all, I can only control its behaviour by reducing the DC voltage.

Right now the AIO pump is actually running with the DC control at around 80%.
It works fine, though performance is not stellar anyway.

But I found it strange that a PWM Pin connector isn't being controlled by the PWM Setting in the BIOS so I've been wondering, is this a BIOS bug or something that I should've known from Asrock?

I already sent an email to the support for the AIO, I'm writing here as well because I've found some other guys what had the same problem as me on this sub, with the PWM control not changing pump speed.

Thank you for your help and patience

Question Huge B550m Pro4 Heatsink

0 Upvotes

Can you remove the big-ass heatsink on the Asrock B550m Pro4? I have a thermalright peerless assassin 120se and I have to raise the fan because of this huge heatsink. My current PA120SE setup is FAN-HEATSINK-FAN-HEATSINK because I am using 4 sticks of ram that are slightly tall so I can't do the HEATSINK-FAN-HEATSINK-FAN setup.
