MAG X870 Tomahawk WIFI - Very loud fan spin-up (100%) for 8-10 seconds before BIOS POST + no GPU temp source in Fan Control

[fatik911turbo15c102df]

Привет,

У меня материнская плата MSI MAG X870 Tomahawk WIFI с последней версией BIOS 7E51v1A82.

Задача 1:
При включении ПК все вентиляторы корпуса (Arctic P14 Pro Reverse) вращаются на максимальной скорости (~2650 об/мин, более 60 дБ) в течение примерно 10 секунд, пока не завершится процедура POST BIOS. После этого они снижают скорость до нормального уровня. Это очень шумно.

Задача 2:
В BIOS Hardware Monitor нет возможности использовать температуру видеокарты в качестве источника данных для кривых работы вентилятора. Доступны только температура процессора, системы, MOS и т.д.

Это ожидаемое поведение? Планируется ли улучшить поведение вентилятора при запуске или добавить поддержку измерения температуры графического процессора в будущих версиях BIOS?

Моя конфигурация:
- 5x Arctic P14 Pro Reverse
- Arctic Liquid Freezer 420 AIO
- и т. д.

Спасибо.

Hello,

I have MSI MAG X870 Tomahawk WIFI with latest BIOS 7E51v1A82.

Problem 1:
When powering on the PC, all chassis fans (Arctic P14 Pro Reverse) spin up to maximum speed (~2650 RPM, over 60 dB) for about 10 seconds until BIOS POST finishes. After that they go down to normal speeds. This is very loud.

Problem 2:
In BIOS Hardware Monitor there is no option to use GPU temperature as source for fan curves. Only CPU, System, MOS etc.

Is this expected behavior? Are there any plans to improve fan start-up behavior or add GPU temp support in future BIOS versions?

My configuration:
- 5x Arctic P14 Pro Reverse
- Arctic Liquid Freezer 420 AIO
- etc.

Thank you.

Most modern gpu's have their fans stop below 50 or 60°C. So that wouldn't be wise to use as a system fan curve. Then it's quite normal for a system to go 100% for a brief period when you power it on. On this board it depends on the fans you use. My noctua fans don't do that when posting, they are in fact very silent. But I have an old system where the 2000rpm blade masters go full speed when powering on.

Is there multiple fan connecting to a single header via splitter? Can you try connect only one and see if this happen? Also, try make some change in the BIOS > Hardware monitor section for the fan curve, ensure it's at PWM mode rather than DC mode.

This is expected behavior, the motherboard wouldn't know how to detect the GPU temperature from BIOS level. On some high end motherboard, they do offer thermistor option and you can place it anywhere and use it as fan curve source, but you wouldn't stick the sensor into GPU whatsoever.

If you have some high end MSI graphics card, you can prob try AI Frozr cooling which is buried in MSI Center > Cooling wizard.

I guess it checks GPU, CPU temperature in real time and adjust system fan based on the result.
I personally don't use it as I don't need more software checking my system status all the time and CPU temperature is a good enough reference for my fan.
