GPU Fan Running at Full Speed Constantly on ASUS ROG Strix Scar 17 (G733ZW)

[EinArlyn]

Hello,

I am experiencing an issue with my ASUS ROG Strix Scar 17 (G733ZW, 2022) laptop. The GPU fan consistently runs at full speed (approximately 7900 RPM) regardless of the GPU temperature, which remains below 50°C even under light load or idle conditions.

What's unusual is that:

1. Occasionally, the GPU fan will completely stop or significantly slow down for a short time, only to ramp up to full speed again shortly after.
2. During gaming or heavy GPU load, the fan can also randomly stop running at full speed and behave more normally for a while, before ramping back up.

Here’s what I’ve tried so far:

1. Updated all drivers (GPU and chipset) using official sources.
2. Reinstalled Windows and avoided installing Armoury Crate initially.
3. Updated and even downgraded the BIOS firmware (currently at 324).
4. Monitored temperatures and fan speeds using Armoury Crate and other tools (e.g., GPU Tweak III). All tools show the same temperatures and fan speeds.
5. Disabled Armoury Crate services and ensured no other ASUS software is interfering.

Despite all these efforts, the issue persists. Has anyone else encountered a similar issue with this model? Could it be a VBIOS issue, hardware sensor malfunction, or something else?

I would greatly appreciate any advice or suggestions, including possible next steps for troubleshooting.

Thank you in advance!

Best regards,
EinArlyn

Hi eXplode,

Thank you for your response and suggestion! I've installed GHelper and tested the options provided, but unfortunately, the issue persists. Despite setting the fan curve to turn off the GPU fan at low temperatures, it continues to run at full speed (around 7900 RPM) even when the GPU temperature is below 50°C. I’ve also tried resetting the BIOS as described, both with and without the charger connected, but it didn’t resolve the problem.

Additionally, I reviewed the thread you linked, but the solutions mentioned there didn’t apply to my case or didn’t work. If you have any further suggestions or insights, I’d greatly appreciate it!

Thanks again for your help!

Best regards,
EinArlyn

"I think you should look for a way to reset the BIOS of your laptop. If you manage to reset the BIOS and it doesn't fix the issue with your laptop, you should send it in for service."

"Before resetting the BIOS, you can download HWinfo64 and check the GPU memory temperature and hotspot temperature.

For my RTX 4080 laptop GPU, under load, the memory temperature is around 80°C, and the GPU hotspot is around 85°C. In idle, these temperatures should be around 50-60°C.

If your temperatures for the GPU hotspot and GPU memory are high, this could also be causing the problem. In that case, you might need to repaste the laptop. For example, in my RTX 4080 laptop, liquid metal is used for the GPU core, while thermal paste is used for the memory chips. The thermal paste is very cheap and dries out after about 6 months."

Thank you for your suggestions. I’ve already checked the GPU temperatures using multiple monitoring applications (including Armoury Crate and others), and the readings are consistent across all of them. The GPU temperature is always below 50°C, and the air from the GPU exhaust feels cool to the touch.

Additionally, I’ve already reset the BIOS settings multiple times, but unfortunately, that did not resolve the issue.

Regarding the thermal paste or liquid metal, I believe this might not be the case, as the temperatures seem to be within acceptable ranges for both idle and light workloads.

For now, I’ve submitted a service request form to ASUS support with all the details of the issue. I’ll be waiting for their response, as all the potential solutions I’ve tried so far have not worked.

Thank you again for your advice, and I’ll update here if I find a resolution.
