Cold Fusion Reactor Engine

A Cold Fusion Reactor Engine is a much improved version of a Fusion Engine.

Heat Sinks
It has 20 internal heatsinks. Actually, this is just the heat dissipation of a Fusion Engine, but it can be directed externally since Cold Fusion doesn't generate significant heat, waste or otherwise.

The internal heatsinks can't be upgraded into Double Heat Sinks, however.

Heat generation
A Cold Fusion Reactor still generates heat when moving, etc., as normal.

This is entropy due to energy conversion into mechanical and propulsion modes. However, the extra heat dissipation capacity saved.

Bulk
This engine is so bulky it can only fit on SuperHeavy units. There has been no way to further reduce the Cold Fusion process in space. It uses 12 center torso slots in Mechs.

Weight
Cold Fusion Reactor engines weight 25% less than regular Fusion engines.

Thrust/Speed
Cold Fusion Reactor engines can enter a permanent Overdrive mode to give +50% speed when compared to their rating.

Tech interactions
Propulsion from a Cold Fusion Engine is incompatible with MASC and/or Supercharger. It is however compatible with the extra strength from Triple Strenght Myomer, but doesn't actually gain extra speed since the myomers are already overtaxed to keep up with the engine.
