COHI Weapons (Capable of Heatsink Integration Weapons)
First designed by the Capellan Confederation in 3026 after a long study of a collection of Raynor's Raiders weapons that the confederation was able to acquire through the black market. During the study it was found that in contrast to Innersphere weapons, Terran weapons had a integrated heat disposal system that allowed for the weapons to be completely heat neutral under most conditions. While incapable of replicating the heat disposal system used in the weapons the Capellan scientists and engineers were able to replicate the integration method for their PPC's. While this new line of PPC's was able to accept any form of heatsink the Confederation had access to it came at the cost of being 10% more expensive and the need for new production lines or completely revamping existing production lines for these new weapons.
However even with these set backs the scientist and engineers working on the project managed to convince chancellor Maximilian Liao the increased performance of the new weapons was worth the cost. Thus the chancellor ordered for several factories to converted along with new factories to be constructed across the Confederation. However the factory build on Tikonov would be lost during the Federate Suns operation RAT. The new COHI PPC designs were quickly copied by the Suns and integrated into their own forces along with the development of more COHI weapons by NAIS. Many of these new designs would be shared by the Suns with their Lyran allies and from there the technology spread to the two remaining houses.
However with the recovery of Double Heatsinks in the 3040's the race to make them compatible with COHI weapons would begin. In 3041 a stop gap method was developed by the Free Worlds League that allowed 2 double heatsinks to be integrated into COHI weapons. However the integration method was highly experimental and resulted in the integrated DHS's only partially sinking the heat produced.
A proper integration method would be devised by NAIS in 3044 thanks to their long experience with double heatsink development. This proper integration method allowed for 3 DHS's to be installed into COHI weapons along with properly sinking the heat generated by the weapon they were integrated in.
By the time of the clan invasion COHI weapons were a common sight across Innersphere forces with many of the new weapons that were developed or rediscovered being reworked to have COHI capabilities.
Rules:
The weapon has to be specified as being a COHI Weapon. Integrated heatsinks remove double their normal sinking capacity from the heat produced by the weapon (If for example a Standard heatsink is integrated into a COHI PPC remove 2 heat from the total heat produced by the weapon resulting in 8 heat being produced when fired). Total crit's and weight of the Heatsinks are added to the weapon. In total 3 heatsinks can be installed into a COHI weapon. Integrated heatsinks reducing produced heat to 0 is allowed.
Double Heatsinks installed into the a COHI weapon before 3044 lower heat by 3 heat instead of 4 along with only 2 DHS's being able to be installed into COHI weapons.
Heatsinks integrated into a COHI weapon can be different from the Heatsinks integrate in the mech itself but not from the other heatsinks that are integrated into the weapon. For example you can't have 1 Innersphere double heatsink and 2 standard heatsinks integrated into a COHI weapon.

If a COHI weapon is crit roll again to determine if a integrated heatsink was hit instead of a critical part of the weapon. The amount of integrated heatsinks will determine how high you need to roll: 1 heatsink (1-4 weapon crit, 5-6 heatsink crit), 2 Heatsinks (1-3 weapon crit, 4-6 heatsink crit) and with 3 Heatsinks (1-2 weapon crit, 3-6 heatsink crit). If heatsink is crit add removed heat back to the weapons total heat production.
Integrated heatsinks don't count to a mechs total heat dissipation. If disabled/destroyed total mech heat dissipation doesn't decrease.
(After all the discussion on integrated heatsinks and other heat dissipation tech that could be developed thought it be fun to do a quick write up for it)
