Which is more effective for cooling on a radiator?

- Yate Loon 88CFM (120x25)
- Panaflo 115CFM (120x38)

The Panaflo has a larger dead zone than the Yate Loon. However, the Panaflo has a higher CFM and static pressure than the Yate Loon. Is this tradeoff in CFM/static pressure versus dead zone worth it?
