Klipper Shutdown trough apparent thermal throttle

Hello,

I've noticed that the CB1 board begins thermal throttling at around 60°C. While this temperature threshold might seem reasonable, it causes Klipper to lose connection due to timing issues ("timer too close" errors). This is particularly frustrating since the CB1 runs relatively hot even under active cooling in a controlled environment.

I'm looking for help regarding this issue, and I have a few specific questions:

1. Is it possible to increase the thermal throttling threshold on the CB1?
If so, how can it be done, and what are the potential risks regarding stability and long-term reliability?

2. Alternatively, is it possible to mitigate this problem through Mainsail or Klipper configuration changes—perhaps by adjusting timing tolerances or connection handling?

Any advice, insights, or shared experiences would be greatly appreciated!

No files, tests, or entry points are named; begin by identifying where CB1 thermal throttling and Klipper connection behavior are configured. Done means documenting whether the threshold or configuration can be changed, the required steps, and the stability risks.
