7.2.5. Effect of cooling on the life of the modules
The modules of the TALEXXengine QLE G2 PRE system are self-cooling and a heat sink is not required. The life of the module
depends to a large extent on the operating temperature. The more that the operating temperature can be reduced, the longer the
expected life of the module. If the permitted operating temperature is exceeded, however, the life of the module will be significantly
reduced.
