\"PE<\/a>Recently we purchased a Dell 2950 III with a DRAC card to investigate adding IPMI support to PA Server Monitor<\/a>.\u00a0<\/span><\/span><\/p>\n

So far it\u2019s great, but what wasn\u2019t so great was the noise.<\/span><\/span><\/p>\n

One blog writes that it sounded like a fleet of jets all taking off at once from an aircraft carrier.\u00a0 I thought it sounded a little more like an air raid siren I\u2019ve heard on movies, or a tornado siren that we hear around here.\u00a0 It actually causes ear pain with the case open.\u00a0<\/span><\/span><\/p>\n

To be fair, the volume does go down with the case on and after the system takes a few minutes to lower the fan speeds, but it\u2019s still way too loud.<\/span><\/span><\/p>\n

\u00a0<\/p>\n

So, This Fan Noise is for Real?<\/em><\/span><\/span><\/h2>\n

After some quick investigation, it became apparent that the bulk of the noise came from the four Dell cooling fans (for reference, fan model number was F126025BU.)\u00a0 <\/span><\/span><\/p>\n

These things are beasts.\u00a0<\/span><\/span><\/p>\n

If they were mounted in the right direction you might think they could lift the server into the air.\u00a0 Because this server will be in an office environment, a low noise level is a must.\u00a0 And since it won\u2019t be heavily loaded, cooling capacity isn\u2019t as important.\u00a0 With that in mind, we bought some quiet consumer-grade fans.\u00a0 Two things are important when you\u2019re looking at replacement fans:<\/span><\/span><\/p>\n
