Editing The Relay Heat Update (section)

=== Your heat can settle anywhere ===

You might see a bay heat up and then just stop at some number, sitting there without moving. That is normal, not a bug. A hotter bay makes less, and making less also makes less heat, so as it climbs it reaches the point where the heat coming in and the heat going out balance each other. The number levels off and holds there. It is simply where that bay settles for its current size and mode. Underclock it or drop a coolant and it settles lower, build it up or overclock and it settles higher.
