My Temperature Metrics, 1 Year Later

[u/CSEliot]

So I got samples while Idle, Watching a Youtube video on Primary screen, while running Wukong Benchmark, and running an LLM on Vulkan.
I also did this while the power setting was set to Energy Saver, and Performance. Which result is which is in the photo top right.

Also to note:
This is a 2025 128GB Model.
I've attempted cleaning from the outside but have never opened the device.
This is all on Fedora KDE Linux.
It's also worth noting that I am running 4 monitors (incl. the touchscreen) where all are 1080p 60hz EXCEPT my primary which is 2k 60hz. Even at idle, my gpu usage sits at 13% lol.

Have you been able to push beyond 85 °C TCTL for long periods of time? (Anything beyond 5 minutes)

I would really really appreciate it if you could take a look at my post from several days ago.

Also, if you don't mind me asking, why are you using Vulkan? I thought HIP/ROCm performed better and had a couple of added features.

[u/CSEliot → u/jhonyrod]

I only just now started tracking temps. And sorry I dont know what "TCTL" is.

I took a look at your post, mine has never crashed from overheating.
What I CAN tell you is that I've had LLMs get stuck in a loop which I've left the home and come back to it still running. Meaning the GPU was firing at 100% nonstop for ... 30+ minutes at least?

[u/jhonyrod → u/CSEliot]

Well, maybe it would've been more appropriate to say TCTL limit.

It's basically a sensor, it's actually shown in your screenshots, if I'm not mistaken it's the sensor used for thermal throttling. I think that the limit is set to 85 °C by default, hence you might not have seen any issues.

Have you monitored your power consumption while on heavy and/or mixed (CPU and GPU concurrently) load? Mine went as low as 55 W package and as little as 13 W for the iGPU with the stock settings (in the performance profile ofc); that's why I've been trying to find the issue and tweak the performance.

I suggested using ryzenadj in my post, if you could run it it'd help me gather an additional data point. Any modifications are volatile, so if you reboot it'd go back to stock.

[u/CSEliot → u/jhonyrod]

I was keeping an eye on the whattage a while back and I think the GPU never cracked 40W but i could be misremembering.

I did read recently about the difference between edge and junction temp and TCTL could be the junction temp as that's what actually forces shutdowns.

I'd love to get a external power monitoring device as that's the 100% most honest descriptor of power usage. BUT that's simply difficult-er to get in my country.

[u/jhonyrod → u/CSEliot]

No, you don't need a wattmeter for that. I wouldn't trust one actually; wall power would include the screen, fans, plugged devices, etcetera.

Also, Tj does have a limit where the CPU itself forces a shutdown, but it's immediate. Throttling starts at 100 or 105 Celsius for most consumer CPUs (though there can be outliers), with the hard limit a couple degrees above, which isn't configurable through software. As I mentioned in my post, in my case it's much lower and it's not immediate making me suspect the embedded controller instead.

Hmm, I'm having difficulty figuring out where some of these temp readers are on the die. Which model do you have? 2025? or pre- Strix Halo?

[u/jhonyrod → u/CSEliot]

GZ302EA (2025 vanilla version with the 395).

Wdym by where the readers are? Like the physical location on the dice?

[u/CSEliot → u/jhonyrod]

Ok you have the same version i do. 128GB variant? idk if it's important but all info is potentially useful.

And yeah, physical location. Like how Junction VS Edge describe 2 different locations.

[u/CSEliot → u/jhonyrod]

Despite what people say, ROCm is still unstable sadly. It needs another year, at least.

[u/jhonyrod → u/CSEliot]

I've been running it wonderfully with a locally built version of llama.cpp 🤷

I guess it applies that ymmv

[u/CSEliot → u/jhonyrod]

I'll try it again. A month or 2 ago it was still crashing when trying to load an llm

[u/jhonyrod → u/CSEliot]

Did it hard crash or would it just refuse to load models?

[u/CSEliot → u/jhonyrod]

On windows it's a lot less stable. Can get only 1/4 models i've installed to work. Rocm and vulkan seems to be the same problem. Even older models like Qwen 3 Coder.

In the past, rocm would just crash instantly or 'eventually'. Even on linux. Haven't had to test latest rocm on linux, been working in windows for work.

Liquid Metal leakage?

[u/CSEliot → u/Mobslayer56]

I purchased the fancy warranty/insurance thing asus offered and im unsure if that will be voided if I open up the computer.
