Heat Sink Specifications
The graph (Figure 15) shows thermal resistance of the socket as well as socket with a fan (Papst 3412/9 GL,
35.9 CFM, 6” muffin) blowing directly on it. For high power dissipation, a specific heat sink lid can be
designed using QFIN software. Please call Ironwood Tech Support @1-800-404-0204.
