Asus ROG Zephyrus 16 GA605WI BIOS Fan curve profiles is too loud

[BMan]

Hello Asus Team

Asus Zephyrus 16 GA605WI BIOS could use some love with Fan curves tweaking.

- When laptop is plugged in, In Silent mode it's running most of the time.
The CPU fan is 1800-2200RPM. The middle system fan is usually running at high 2000 - 4000 RPM. GPU Fan is off.

- When laptop is plugged in, In Balanced/Performance mode is even worse behaviour and fans even ramp up more speed.
The CPU fan is 2600RPM. The middle system fan is usually running at high 4000 - 6000 RPM. GPU Fan is off.

Laptop is quite is not running intensive tasks, CPU is around 7 - 8 Watts and CPU temperature is around 54 Celsius. Nvidia GPU is 52 Celsius and using 17 Watts of power.

The Fans have a bit of high pitched whistly sound, so it's important to tune it down a bit than it's right now.
I can understand that you would refer me to Armoury Crate or G-Helper to tweak fan curves.
But the BIOS still have the final say over the actual minimum Fan curves regardless of the user tweaking.

I understand that Fans tweaking is a trade-off of Thermals and Noise. In my case as a user, I want more control to favour more silent experience and let the laptop run hotter, but I can't achieve that because BIOS would always run the fans specially the middle fan at louder noisy RPM.

Actually notebookcheckreviews also have highlighted in the testing the fan as a complaints in their review

And in their written review here: https://www.notebookcheck.net/Asus-ROG-Zephyrus-G16-2024-review-The-slim-gaming-laptop-now-with-AMD-...

My feedback is not one off, but something that affects both Intel and AMD variants. So, Hopefully it can get more attention from Asus Tech Team and BIOS developers

Hi @BMan ,

Due to the need for your personal information.
I have sent you a message, please check✉. Thank you

Thanks for sharing and bringing to their attention. Not sure why personal information is required from the support rep, other than to try take the conversation away from a public discussion?

The fans on this system are noisy and distracting in a way which feels completely unnecessary. The bios seems tuned far too aggressively on the fans, particularly the middle fan. The other 2 fans are reasonable, but that middle fan starts to crank up and down constantly during medium - high usage.

Glad to hear it's not just me, there's not much information out there regarding this particular model. My numbers are pretty much identical to yours quoted (temps, rpms)

Agree regarding silent mode also. Can we just get more tolerance here on the BIOS to allow this to be more manually tuned, or alternatively just refine this better for acoustics - particularly the mid-fan.

Hi @ctyldsley ,

Thank you for your feedback. Could you please provide the following information via private message? I will forward it to the internal team for evaluation and reference. Thank you!

To add more public information of my testing so far on trying to get silence experience:I have tested setting the iGPU or Eco Mode and setting the fans as low as possible while being plugged in to charger.
It did help with being 0dB with fans are completely off, laptop is raised on stand above the desk.

It seems the highest temp limit before bios forces the fans to kick in is 70 degree Celsius, and having Nvidia GPU running pushes the passive cooling beyond this temp limit.
RTX 4070 consumes 14-15 watts at Idle-light tasks.

Turning off the 4070, seems to maintains temps around 52 in Balanced mode, and fans are off.

My current problems right now, and I will open a new thread regarding it is that Nvidia RTX 4070 seems to be hardwired to HDMI port, so I can't use HDMI with my external monitor with iGPU.

iGPU USB-C works well at 4K 60HZ, but iGPU USB-C doesn't seem to want to output 4K 120Hz.
I'm not sure why yet.
I have LG C3 as external monitor.

When dGPU enabled in Balanced mode, seems when fans kick in, that minimum RPM the go for is 1800 and they accelerate to 4000 RPM range.

The whistling or high pitch noise is because sudden static pressure is built up.

My suggestion is to attempt lower RPMs 500 or so to contain the heat first, if it failed it can attempt another step and see if heat can be contained.
Instead of just rushing to 4000 RPM level.

I recommend that the fans or acoustic engineering team uses the laptop for a week and work on improving the acoustics experience.
It's easy to make a laptop to win benchmarks without thermal throttling, but takes a small extra effort to win the consumers with small tweaks to acoustic experiences like this.
