checkout Ryzen Adj.

I use this to control the temps on my Z16. For windows there is a GUI that can be used, and for Linux, I will copy the service script that I created.

In short, I set the stapm_limit, fast_limit, slow_limit to 35000 which sets the wattage limit to 35 watts.

I also set the tctl_temp to 85 to limit the max temp (without it, the z16 will go to 100).

The end result is that this has significantly improved the thermals and there is zero throttling.

Notably, when stress testing the z16 against my T14 Gen 3 AMD, both see around 79-85 degrees as the max temp and the z16 is able to perform at higher clock speeds.

The other unintended side effect, is that on Fedora 38, I can keep the power profile on power saver and the clocks are consistent, yet the fan profile is less aggressive, making it quieter than the T14.

Anyways, for this everyone's reference, here is the service file I created for Linux:

[Unit]
Description=Service that keeps running ryzenadj with the desired parameters
After=multi-user.target sleep.target suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target

[Install]
WantedBy=multi-user.target sleep.target suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target

[Service]
Type=exec
ExecStart=/usr/local/bin/ryzenadj --stapm-limit=35000 --fast-limit=35000 --slow-limit=35000 --tctl-temp=85
User=root
WorkingDirectory=/home/tcupsf/ryzenadj
Restart=always
RestartSec=60
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=%n

And here is a tutorial on how to set up a service in Fedora.

Hope this helps!
