Question CPU water cooling pump is 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.

pump noise

When you updated BIOS version, CMOS was reset to that BIOS version defaults that apparently has different defaults for fan/pump control. You may need to enter BIOS/UEFI settings and make changes to pump control, adjust its RPM curve and/or set a couple of seconds delay and possibly switch pump's header to PWM mode instead of DC mode, they use different systems for RPM control.
No, full speed is not going to damage pump, they are made to work full speed all the time and most people force them to do so for better cooling at idle. I always set them like that and never lost one. If that doesn't bother you there's nothing you have to do.

Hi Mike, I specifically wrote down the BIOS settings before installing the update. -> I've reset everything to the way it was before. Just to be on the safe side, I also cleared the CMOS yesterday, but unfortunately, I still get a loud pumping noise when booting. (After booting, the pump/fan control works perfectly.)

Unfortunately, I don't have a good understanding of electronics, but is it possible that the pump is being controlled incorrectly during bootup? Perhaps like a fan.

It is a "Fractal Lumen S36" AIO by the way
(I got these settings from another thread)

Here are the full pump and fan bios/uefi settings; maybe I made a mistake:

CPU Fan 1 Setting = Customize
Fan Step Up = 5.0 Sec
Fan Step Down = 5.0 Sec
Temperature 1 = 60
Fan Duty for Temperature 1 (%) = 15
Temperature 2 = 70
Fan Duty for Temperature 2 (%) = 25
Temperature 3 = 75
Fan Duty for Temperature 3 (%) =35
Temperature 4 = 80
Fan Duty for Temperature 4 (%) = 85
Critical Temperature = 85


CPU_FAN2/WP Switch = W_Pump
Water Pump Control Mode = DC Mode
Water Pump Setting = Customize
Water Pump Temp Source = Monitor CPU
Temperature 1 = 60
Fan Duty for Temperature 1 (%) = 60

Fan Duty for Temperature 2 (%) = 70
Temperature 3 = 70
Fan Duty for Temperature 3 (%) = 75
Temperature 4 = 75
Fan Duty for Temperature 4 (%) = 80
Critical Temperature = 85

CHA_Fan1/ WP Switch = CHA_FAN1
Chassis Fan 1 Control Mode = Auto
Chassis Fan 1 Setting = SIlent Mode
Chassis Fan 1 Temp Source = Monitor CPU
Fan Step Up = 0 Sec
Fan Step Down = 0 Sec

CHA_Fan2/ WP Switch = CHA_FAN2
Chassis Fan 2 Control Mode = Auto
Chassis Fan 2 Setting = SIlent Mode
Chassis Fan 2 Temp Source = Monitor CPU
Fan Step Up = 12 Sec
Fan Step Down = 12 Sec

CHA_Fan3/ WP Switch = CHA_FAN3
Chassis Fan 3 Control Mode = Auto
Chassis Fan 3 Setting = SIlent Mode
Chassis Fan 3 Temp Source = Monitor M/B
Fan Step Up = 0 Sec
Fan Step Down = 0 Sec

CHA_Fan4/ WP Switch = CHA_FAN4
Chassis Fan 4 Control Mode = Auto
Chassis Fan 4 Setting = SIlent Mode
Chassis Fan 4 Temp Source = Monitor M/B
Fan Step Up = 0 Sec
Fan Step Down = 0 Sec
Should I try a PWN mode setup? What would be a suitable setup for this?
Thanks for your support. I've been a console gamer for years... but it just annoys me that consoles are so slow 😀 That's why I switched to PC... Well, at least you didn't have to deal with so many settings on consoles... I guess that's the flip side of the coin.

Can you show a photo of your system with side panel removed?

Note - pump is integrated into radiator. Radiator can not be placed at top position of pc case.

Pump is connected with 3pin fan connector. Correct?
Then it can be regulated in DC mode only. PWM mode is not compatible with it.

Hi SkyNetRising, thank you for your help and support,

connected with 3pin fan connecter, exactly.

"Note - pump is integrated into radiator. Radiator can not be placed at top position of pc case."
->radiator is on top, damn. But I can't use it any other way. then I would need a new case:/ because at the front/bottom is the radiator from the 4090 suprim

By the way, the radiator has been attached like this since January 2024 and there have never been any problems before, only since the BIOS update 3.20.

*see pictures

Huh!? Everything I've read suggests mounting the rads on top is one of the preferred ways to mount.

Is that not correct? My AIO has run perfectly with zero issues. This is my current orientation. I thought of turning the CPU block a quarter so the tubes are starting downward, but this puts it right on top of my primary ssd. So I left it as is.

What are the options for Water Pump Temp Source?

These Fan Duty for Temperature settings seem high, if I understand them correctly.
I understand it as FDT1 to run at 60% speed of the pump when the temp reaches 60C.
Then at 65C is runs at 70% pump speed
Then at 70C it runs at 75% pump speed
Then at 75C it runs at 80% pump speed

I would adjust these temps and percentages to be more in line with what your readings are during normal use.

Hey sup dingo,

copied this setup from another thread, but so far everything has been/is working fine. However, I'd be willing to make a few adjustments here and there. For now, I'm waiting for Skynet's response.

That is an option only, if pump is integrated into cpu block.

If pump is integrated into radiator, then radiator can not be placed in highest point of the loop (top position of pc case).
You get air bubble accumulation in pump. That prevents proper liquid flow causes weird noises and eventually kills the pump.

Oh, right. Thanks for explaining that. I didn't realise some incorporate it in the CPU block and others don't. I thought they'd mostly be the same findemantal design.

SkyNetRising forgot a "if" in his comment, which induced a lot of confusion. Most AIO have the pump in the CPU block. Some older models (especially from MSI) had the pump in the radiator but almost nobody does that anymore since it's too easy to install it wrong, while it's almost impossible to do a mistake when the the pump is in the CPU block (as long as the top of the radiator is higher than the pump you are fine).

Cheers. Thanks for that. Makes sense and confirms my understanding.

Hey SkyNet,
you asked for pictures, I posted some. Did you notice anything unusual?
The problem must be fixed. 😀
