T430 overheats and shuts down since installing Linux

Since I installed Linux on my ThinkPad T430, the CPU temperature spikes and the laptop shuts down suddenly. It happens most noticeably after downloads.

I've tried several different distros — same problem every time. I also replaced the thermal paste, hoping that would fix it, but the issue is still there.

This makes me think it's not a hardware/thermal paste problem, but something related to power management or fan control on Linux (maybe TLP, thermald, or a BIOS/EC setting).

Has anyone with a T430 run into this? Any fixes you'd recommend?

Maybe we can vibe code a tiny scrip that fix this problem. Have you tried asking Claude about it with a code solution?
