Just like an electronic data processing chip [[gem-gum on-chip factories]] will need some thermal management.

The characteristics of the thermal management and the reason for it's necessity are quite different 
when compared with electronic chips like CPU's though.

== Gem-gum factories will not run very hot ==

Usually for everyday production devices there will be no need to squeeze out the last bit of performance like in electronic data processing chips.
Once a satisfactory production speed is reached there is not much motivation to run it faster and hotter.
Except for very special not widely occurring applications.

So [[gem-gum on-chip factories]] for everyday use will generally run rather cool.
Especially once [[piecochemical mechanosynthesis]] gets more optimized.

It is difficult to get a realistic estimation for waste heat disipation for [[piecochemical mechanosynthesis]]. 
It is straightforward to get a worst case case estimate [[piecochemical mechanosynthesis]]. 
Even for the worst case it still leads to a feasible design. 
A real implementation will perform a lot better though. 
See: [[Nanosystems]]

When it comes production or "un-production" via recomposition of [[microcomponents]]
at leisurely everyday usage speeds then waste heat will likely not even be perceptible at all.

== Active cooling make more materials accessible to mechanosynthetization ==

Active cooling to reduce atom placement error rate even further

While [[piezochemical mechanosynthesis]]] works just fine at room temperature
it has even lower error rates when it is cooled down to cryogenic temperatures (by mean of internal machinery).

Also with cooling to cryogenic temperatures many materials become accessible to [[mechanosynthesis]] that
are otherwise inaccesible due to high rates of surface diffusion (atoms jumping randomly around from the thermal jostling) at room temperature.
Cooling down can reduce diffusion speeds from the speed of sound to one jump per year and for a whole mol of particles (6.022 * 10^23 particles).
It's an exponential relationship.
The materials mostly in focus here are pure metals with nontrivial surface arrangements.
Pure metals are not the prime focus of [[gem-gum technology]] and their tendency to diffuse at room temperature is one of several reasons for that.
Obviously if a final product with pure diffusion prone metals inside shall operate at room temperature, then after finished mechanosynthesis
everything needs to be finished and packaged up nicely such that do diffusion can occur where not desired.

Cooling also might help in reducing holding constraint requirements when
mechanosynthesizing more floppy lower dimensional structures (2D and 1D)
like e.g. 2D [[graphene sheets]], [[nanotubes]] and [[ethyne chains]].
