So I have built a new PC with this motherboard and the first time I turn it on my fans went on very loud I have installed Armoury Crate and then change it to standard mode which seems to solve the problem for the time I am being on my PC, but the real problem is now that I have to switch to standard fan speed mode every time I start up my PC, I have tried and change fan speeds in BIOS but it didn't change anything for me. Anyone had this problem and would like to help me out ?

Hi, just built my system and have encountered a problem i didnt know existed and was wondering if anyone else with the ROG STRIX x570-i motherboard has the constant loud PCH fan noise. The fan starts off at like 1k rpm on boot but goes up to around 6k and is extremely noisy!

I have latest bios, drivers and temps on everything are good. I do have a m.2 ssd in the back of the motherboard which i was concerned about but the temps on bot m.2 hover around 59 at idle - havent checked adt load yet.

I know there are methods like modding the bios but i dont feel confident in myself doing that and feel i would mess it up. So if anyone has any other solutions to this I would really appreciate your info and help as everything else in my pc is silent except that fan!

Just bought a 5950x + ROG Strix X570-F Gaming and I tried using Armoury Crate - but I just cant find a way to control the fans.... I want to build special fan curves because the sounds drives me crazy !

please help

The PCH_FAN header looks like a 4 pin header so should be controlled via PWM. Anybody able to confirm? Thanks!

I am a complete noob in building a PC. This one is my 1st ever proper pc build. I have 3700x as my CPU and right now, my CPU sits at around 35-50C idle.

I have an NZXT H500 with their Kraken x63 AIO. When setting up the build, I literally plugged in fan connectors in whichever ones I found closer. Now my fan curves are all messed up. Some fans run like crazy and some just sit there quietly. Also, I am unable to control some in software/bios due to them being plugged in a connector that doesn't support full control.

I have a 1x 140mm Fan on the top (exhaust)

1x 120mm on the back (exhaust)

2x 140mm fans on the front for the AIO (intake)

The AIO pump connected in a random fan connector

Now, where do I plug the connectors for every particular fan based on my motherboard so I am able to control them appropriately in the Asus' AI Suite? Also what could be my optimal fan curves based on every fan.

i tried updates and new installations of AI Suite and Armory Crate.

But there is no Fan XPert or anything similar.

I can adjust settings in BIOS but that is not working very well. I set all Fans to minimum Speed iin BIOS when below 50°C but when Windows is booting, Fanspeeds go up. In Armory Crate i can set Fans to "silent" and the Fans spin slower. But then when i game, the system gets too hot.

I need a working Fan Control for Windows. AI Suite is without Fan XPert or similar. Armory Crate also has nothing like this in it. what am i missing?

Asus ROG Strix X570-I Gaming, AMD X570 mini-ITX Gaming motherboard:

My M.2 is mounted on the rear, since my heatsink was impossible to remove without stripping the screws. The PCH Fan that cools the empty front-side M.2 slot randomly decided to crap out last night waking me up around 3AM. It was stuck running around 5K RPM and there was no way to easily disable the fan.

Here's how I solved the issue:

• Power cycle - No improvement

• Dust Everything - No improvement

• Remove Heatsinks - No improvement

• Install Bios Update - No improvement

• LibreHardwareMonitor - No Fan Control options for the PCH fan

• Open Hardware Monitor - No Fan Control options for the PCH fan

• Bios Hex Editing - Not worth bricking the board or risking warranty

• Disconnect PCH Fan connector - Silence at last!

  1. Shut down the system

  2. Remove the GPU

  3. Locate the PCH Fan Connector between the M.2 Heatsink and bottom left mounting hole

  4. Disconnect the connector from the motherboard

Hey Guys,

I'm confused.

I just build my new PC with a friend and everything runs smooth except the fans.

I went into the BIOS settings and there my misery started. We installed an AIO so I disabled the "CPU Q-Fan Control" - because according to my understandig there is no classic "CPU-Fan" in my system.

So far so good. In my case (SilentiumPC Signum SG7V EVO TG ARGB) are 4 x 120mm fans preinstalled. These fans are plugged into the PVM ARGB Splitter.

When I turn on my PC and I open Armoury Crate and set the Fan speed to "Standart", the temps and fan speeds in desktop are fine.

Until I turn on a game. Then the fans start to go full speed and then again low speed at very short intervals.

I went into BIOS again and set the Seetings to "DC-Mode" (3 Pin fans) - doesn´t solve the problem. I tried to manually adjust the fan curve but he doesn´t allow me to go lower then 60% usage.

HWMonitor shows 4 fans on my Mainboard: AUXFANIN0 (same RPM as Chassis #2 according to HWMonitor) AUXFANI2 (same RPM as Chassis #4 according to HWMonitor) Chassis #2 Chassis #4

The fact that the Motherboard shows 4 fans confused me even more. Shouldn´t it show 7? 4 Case fans + 3 AIO fans.

My questions are:

1. Is disabling the CPU fan the correct way?

2. Why does my PC goes against the settings given by Armoury Crate?

3. How can I set those fans that there is a steady and constant amount of cooling to minimize the turn up and down thing?

CPU temps are fine. Never above 80 degree.

Thank you in advance & have an awesome weekend!

Cheers.

Warning: These instructions offer a solution to a long standing problem but it involves BIOS modification. Before proceeding, exercise caution and be fully aware of the risk of bricking your motherboard.

ASUS ROG Strix X570-I motherboard (and others) have had an annoyance: The PCH fan which is audible at 3.5k rpm and becomes a loud high pitch mosquito whine at higher speeds (which can reach higher than 6.5k rpm) (see here for instance). The fan curve makes it climb to these high rpms even when temperatures are not very high (e.g., ~6.4k rpm @ 75 degrees). Many solutions have been tried, including modding the BIOS to enable editing the fan curve. This worked great until before BIOS version 3406 (AGESA 1.2.0.0) at which ASUS enforced only non-modded flashing for X570-I (X570-E and -F are not blocked yet). See related post by modder (in German).

A recent post offered a way for editing a BIOS setting that helps prevent the chipset from getting too hot in the first place by enabling something called ASPM. This seems to help as some have reported. But did not keep the fan quiet enough for others, like me. But the method itself that was used was a great source of inspiration because it makes your brain pop this question: “Would it be possible to directly edit the PCH fan curve hidden in the bowels of the BIOS?” I embarked on a journey yesterday to answer it.

Like many BIOS fan curve settings that use lower-middle-upper specification points, the default PCH curve is specified by (55°,0%),(60°,40%),(93°,100%). A much quieter curve would need just one value changed (PCH Fan Middle Temperature: 60 -> 80):

The following is how I did this change on my X570-I with BIOS version 3603 (that I recently upgraded to). And it worked!! The main caveat that needs attention is that the variable offset at which this setting needs to be written may vary depending on the BIOS version. So it is important to get the correct offset.

Phase 1: Getting the correct variable offset for your BIOS

Tools:

1. UEFITool: UEFITool_NE_A58_win32.zip from https://github.com/LongSoft/UEFITool/releases

2. Universal IFR Extractor: https://github.com/donovan6000/Universal-IFR-Extractor

Steps:

• 1. Locate your BIOS CAP file (or download it from ASUS)

• 2. Load CAP file into UEFITool

• 3. Ctrl-F to search and type “pch” in the Text tab:

• 4. Export the found results to file Section_PE32_image_Setup.sct

• 5. Load Section_PE32_image_Setup.sct into Universal IFR Extractor and click Extract to save the result to a text file:

• 6. Search for “PCH Fan Middle Temperature” in the test file and write down the variable offset (0x3A in this example):

• Note it is a single byte value and it has a value of 0x3C (=60 decimal, the 60 degrees middle temperature value)

Phase 2: Modifying the PCH curve in the BIOS

Tools:

1. The efi file (modGRUBShell.efi) from release 1.3+ from https://github.com/datasone/grub-mod-setup_var/releases

Steps:

• 1. Format a USB drive (small is OK since we only need 3MB), making sure the file system is FAT32.

• 2. On the USB drive,

• a. Create directory EFI at the top

• b. Create directory BOOT under EFI

• c. Copy modGRUBShell.efi under EFI\BOOT and rename it to: bootx64.efi

• 3. Reboot and enter BIOS, and from the Boot menu, boot using the USB drive. Selecting the USB drive under Boot Override (“UEFI: SanDisk, Partitions 1” in this example will do that):

• 4. This should take you to grub> prompt. Once, there, type: (Warning: Your BIOS may need a different value than 0x3a*, depending on what was found in Phase 1)*
  setup_var_cv QFan 0x3a
  This does not change any setting; it just lets you see what is currently stored. You should see “offset 0x3a is: 0x3c” (0x3c being the current value, which is 60 in decimal indicating the middle temperature setting). If you don’t see this, something is not right and you may want to stop here.

• 5. We are now ready to make the change. To do this, type: (Warning: Your BIOS may need a different value than 0x3a*, depending on what was found in Phase 1)*
  setup_var_cv QFan 0x3a 0x01 0x50
  which means change variable 0x3a within the QFan Varstore to value 0x50 (80 in decimal). The 0x01 means it is a one byte change. Steps 4 and 5 should look like this screenshot:

• 6. The change is now made. But for it to take effect, you must hard boot. Hold the power key until the computer shuts down then power it back up.

• 7. Enjoy the quiet.

Hey everyone, as you may have expected, it's the pch fan that I'm asking.

How do you guys get rid of that high pitch 24/7 5000rpm?

I tried LibreHardwareMonitor but the pch fan won't change no matter how I adjust #3,4,6,7. and they all showed 0rpm.

I tried replacing the thermal pad under the heatsink but no improvement so far, it's still ramping up to 5000rpm idling.

a few posts mentioned modding the bios but some also suggested that it won't work with newer bios.

I'm thinking of replacing that fan with noctua's a4x10, not sure if it'll fit.

do you guys have any solutions?

Edit: update!

https://www.reddit.com/r/FormD/comments/ktt4wr/dropping_your_strix_x570i_board_chipset_temp/?utm_medium=android_app&utm_source=share

As the title says, am I be able to control PCH fan somehow, reducing volts, purely change the speed or any other tricks? Sound of that fan sounds like a dentist drill and making it a really annoying when you can hear it too easily.

So I've just about had it with the fan noise from the X570-I, and while I realize it's necessary, it's not so bad until the really warms up and starts going at like 7k RPM.

My goal would be to keep it lower, which I'm hoping I could accomplish with just better airflow over the heatsink on the board to just try and move some of that heat off, and thusly slow the fan. Right now it will get up to 75 or so and maintain that, but with a 7k RPM 30mm fan just howling like a monster, and the heat just saturates the heatsink and won't come down. Once it gets to that 75, it just stays there - even hours after the load has come off.

Anyone happen to have the same board (or in general struggles with X570 active cooling, because I know it's a generational thing) and have some advice for how they arranged cooling? Right now I'm just running dual exhaust on the front through a 240 AIO rad, but I'm thinking of switching to double intake and taking the easy route by adding a 92mm noctua to the top just to get some cooler air moving past the chipset maybe. This was going to be my first step before moving to a printed tophat, or some other cooling method, but if anyone else has tips or a config with good results, let me know.

Hello everyone

i just got my asus rog strix x570-i mini itx and was wondering if a PCH fan at around 5000-6000 RPM is normal? it has tons of air flow and the temp of the CPU are rather good ~45 degrees. I have the lastest bios version 1405, AMD chipset driver 19.10.22 and so on. All is up-to-date.

my build is:

MB: Asus Rog Strix x570-i gaming mini itx

CPU: AMD 3700X

CPU cooler: NZXT kraken x53

RAM: Corsair Vengeance LPX DDR4-3200 C16 BK DC - 16GB

PSU: Corsair SFX series SF600 Strømforsyning - 600 Watt

GPU: ASUS Rog RTX 2060 OC

cabinet: NZXT 440 (i know its a ATX case but my Ncase m1 v6.1 was cancelled because of corona :()

Also where is the PCH fan located? top left corner where there is a small fan i can see connected to the HS fan and is running around 1200 RPM (cant hear it)

thanks in advanced

Hi everyone,

I am running into a weird issue. I normally have the following setup in Q-fan :
CPU Fan : Disabled (running an AiO that controls its own fans : Fractal Design Celsius+)

Case Fan 1 : DC control in Q-fan

Case Fan 2 : DC control in Q-fan

AiO : disabled in Q-fan

M.2 fan : DC control in Q-fan

In this original configuration, everything works smooth, I can set manual curves etc. Note : all my fans are DC control fans, not PWM. Only my AiO is PWM capable, but it runs its own control loop at present.

If I try to set my AiO to PWM control in Q-fan, it works perfectly, but I lose actual control of the M.2 fan header : the latter just jumps to 12V/100%, whichever control mode I set (Disabled, Auto, PWM, DC...). This happens in both Fan Xpert and if I'm playing with it from the BIOS (latest installed 3405). If I set the AiO control back to Disabled, everything works again. Case fans 1 and 2 seem to be completely unaffected by this.

Is there a bug in the header controls in the BIOS ?
