Subject: sudden shutdown by overheat

I am currently using JtR under the following system configurations:

- Operating Systems: Linux Mint 21.3, Linux Mint 22.1, and Microsoft 
Windows 11

- GPUs (for OpenCL use): AMD Radeon RX 6800 XT and AMD Radeon RX 6900 XT

I would like to report an issue I am experiencing on both Linux Mint 
21.3 and 22.1 when running JtR using the --format=ZIP-opencl option to 
enable OpenCL, along with the --prince=password-new.lst option to 
utilize PRINCE mode. Under these conditions, the GPU temperatures for 
both the Radeon RX 6800 XT and RX 6900 XT exceed 110°C. When the ambient 
room temperature is in the upper teens Celsius (around 17°C or higher), 
the entire system forcibly shuts down — including the operating system — 
typically after one to two hours of operation.

I am reaching out to kindly ask if anyone might have any suggestions or 
preventive measures to avoid such shutdowns from occurring. If anyone is 
aware of a potential solution or workaround, I would greatly appreciate 
it if you could share your insights.

Thank you very much in advance for your time and assistance.

Sincerely,
Dai
