Anyone using a Mugen 2 with 4 fans?

[Cliff Burton]

I tried a quad fan setup with the Scythe Mugen 2 and 4xScythe Ultra Kaze 2000rpm and my results were:

From 1 fan pushing to 2 fans in push and pull --> -3ºC load difference.
From 2 fans push and pulling to 4 fans push and pulling --> -1ºc load difference.

So there was no noise/performance benefit. The Ultra Kaze 2000 is rated at 33dBA so you get:

1 fan | 33dBA
2 fans | 33+3=36dBA
4 fans | 33+3+3+3=42dBA

+9dBA to get only a 4ºC difference it's definitely not worth it.
