Question CPU water cooling pump extremely loud during Windows startup (100%)/boot after updating BIOS ?

[dnbrules]

Motherboard: ASRock X670E Pro RS

Hi guys, i need help pls :/ after updating to BIOS version 3.20, the water cooling pump on my cpu (AMD Ryzen 7 7800X3D + Fractal Lumen S36 AOI) is activated extremely agressively/loud during Windows startup, for about 2-3 seconds. After that, everything runs normal... but think this could damage the pump permanently after some time... i need to fix this somehow. -any ideas?

Is it possible that the pump is receiving too much voltage and is therefore pulling so hard when starting?
The problem didn't occur with my previous BIOS version. Everything seems a bit strange.


The mainboard has no direct connector for the pump. I built the PC with a friend and he said the pump would have to be connected to cpu_fan2/WP Switch.
Here are the current settings in Bios:
CPU_FAN2/WP Switch = W_Pump
Water Pump Control Mode = DC Mode
Water Pump Setting = Customize
Water Pump Temp Source = Monitor CPU

Unfortunately, I'm not very familiar with the whole topic yet and need some help 🙁
Thank you very much in advance (also, sorry for my poor English 😀)

Welcome to the forums, newcomer!

The problem didn't occur with my previous BIOS version.
If I were you, I'd revert to the older BIOS that you were on, if it was 3.10. Though out of curiosity, did you update the chipset drivers prior to flashing the BIOS to 3.20? Also, did you clear the CMOS after verifying your BIOS was flashed successfully?

Is it possible that the pump is receiving too much voltage and is therefore pulling so hard when starting?
Voltage? No. Perhaps a delayed signal from your CPU fan header? Yes.

Regardless, your pump shouldn't be damaged.

Hello Lutfij Thank you for your help.

I still had a old BIOS version from 2023 (2.02). Since I'm not that familiar with it, I wasn't aware that it was important to upgrade my BIOS version. That means I updated from 2.02 to 3.02... (I read that 3.02 includes all previous changes/improvements and that you don't have to update one after the other in chronological order). I didn't update the chipset drivers beforehand. Damn 🙁 Should I install the chipset drivers now? You probably mean AMD chipset driver version: 7.01.08.129.


"Also, did you clear the CMOS after verifying your BIOS was flashed successfully?"

-I'm sorry that I have no idea😀 could you tell me what exactly cmos means and how I can clear it?

Kind regards ~dnbrules

I'm informed now. So, this is how I understand it: -CMOS reset/clear resets all manually configured BIOS settings to default, but the current BIOS flash version remains. After I updated the BIOS from 2.02 to 3.02, the settings were already reset to default. Should I still reset it manually again?

Not if you verified it's updated indeed, you should see it on first page in BIOS. CMOS holds in memory powered by CMOS battery when MB is not powered by mains. It holds not just changes made in BIOS but its copied from it. When you reset CMOS iit reads in whole of BIOS and everything actually works from it. When BIOS is flashed with any version it's retained in it's EEPROM (Electrically Erasable/Programmable Read Only Memory) chip which is intermediate between all MB elements and OS. It also contains programs for it's self check and future flashing etc.
As for you noise problem. Does it happen to stop when OS starts loading ? If it does, it's most probable that cooling is controlled by software in OS which doesn't start until drivers are loaded.

Hey CountMike,
thanks for your support and thanks for the info.

No, as I said, the pump's extreme startup noise only started after the BIOS update 3.20. It only occurs during startup/boot and always sounds the same. After the unusual pump noise, a normal startup noise follows, as before. Then Windows starts normally, and the pump runs. I'm only concerned about this loud noise at the beginning... I wonder what the cause is... Lutfij said that the pump can't actually be damaged by it. But it shouldn't stay that way.I've added a short video link here where you can hear the noise. Please listen with headphones; unfortunately, it was recorded a bit too quietly. 1. You can hear the loud noise. Next step: 2. The pump is activated normally (suction noise).

Kind regards ~dnbrules


-Or was it possibly intentionally caused by the BIOS update to ensure the pump was controlled? As described, I previously had a very old BIOS version from 2023... Unfortunately, I haven't found anything in the changelogs regarding pumps/control that would suggest this... although only basic updates/changes are listed on the ASRock website. Complete logs are unfortunately missing.
