Hi! I just bought a firewall that is very loud, and the biggest problem is the two fans in the back ( 2 x sunon pmd1204pqbx-a 40mm fans ) running at full speed. The firewall is 1 unit rackspace 19" with pfSense installed on it. The CPU is a Pentium 4 2.8 GHZ with a heat sink on top. The air is lead through a plastic tunnel across the unit with the fans in the back and the CPU in the front. Now my question is: Do i really need two fans running at full speed. Can i reduce it to like 5v. Will that affect the performance or do I even risk burning the CPU? Are there any quiet fans I can replace them with? Any help appreciated...
