MEC Fan Details and Replacement Suggestions

I just pulled out the fan in my spare MEC. The fan and the vents are all located on the same side of the MEC as the power switch and the plug. The power supply is located here too.
The air flow is all going to happen in this local area, so I think the fan's primary purpose is for cooling the power supply. I don't see how it would move much air from the internal part of the MEC where the cards are located.

Here's some info on the MEC fan:

Panaflo DC Brushless
Model: FBA08A12L
80mm fan
12V - originally 3 wire but it appears Ensoniq removed the RPM wire.

From a web search, the critical performance specs are:
- 24 CFM
- 21 dBA

Picture of my old fan:

Replacement Fans
If you do want to put in a replacement fan, the Noctua's are a good bet because you can get the same air flow with lower noise, and based on what damien wrote it's not clear you need much airflow anyway. I put 120 mm Noctua FLX fans in my Magma.

Specific model numbers:

Noctua NF-A8 FLX
-3 flow/noise levels:
-30 cfm - 16.1 dBA
-24 cfm - 12.9 dBA
-17 cfm - 7.9 dBA (this is close to inaudible)

Noctua NF-A8 ULN
-2 flow/noise levels:
-20 cfm - 10.4 dBA
-15 cfm - 6.5 dBA (this is even closer to inaudible)
