All the better! If the incoming fan is filtered, and has a bit more
airflow than the outbound fan, the extra lost through the holes will keep
the dust-bunnies out. I haven't checked for the 3" fans, but the 5" fans
(from Rotron, at least) were available in both the 7-watt version (whisper
fan), and the 14-watt version (more noise, but more airflow). If there is a
similar pair available, this sounds like the way to go. With the original
7300's fans, run the inbound one on the full 12VDC, while sending reduced
power to the other.
