| Mac Classic sound level? |

I'm trying to guage the expected sound level from my Mac Classic. It seems kind of loud to me, and is humming at a particularly irritating frequency. My phone decibel app is measuring about 59-60 dB when set directly in front of it under the "lip."
I replaced and recapped the Analog board and it's I replaced the fan with a modern Noctua fan rated for 19.8dB, and if I had to guess I would say the noise sounds more like a CRT buzzing than the fan noise.
Could over-voltage be an issue? I measured about 5.08v out at the floppy scsi 5v pin. |

Oh, I also forgot to mention, there is no spinning hard drive installed right now nor floppy usage to contribute to the noise. |

Crack it open and have a listen it'll be pretty obvious what the culprit is. Apart from fan noise you shouldn't be hearing anything. |
