As mentioned earlier, my homelab server is a HPE ProLiant ML110 Gen11 which is a single-socket Intel Sapphire Rapids-based server. One problem with this server is how much noise it generates. I swear, the ML110 Gen10 was much quieter.
It’s a big trouble especially since right now I’m “houseless” meaning I’m living with my brother and have my ML110 in a bedroom closet. However, with the default power settings it’s still very noisy especially when running a cluster of Tor relays.
To fix this:
- Log into iLO.
- Go to Power & Thermal.
- Click Power Settings.
- In the Power Regulator Settings, select Static Low Power Mode.
- you’ve done that, select Apply.
While noise won’t go completely, it’ll become pretty bearable when inside a closet. And oh, it’ll run cooler.
Keep in mind that there might be some performance penalty as it’s on a low power mode. I haven’t done benchmarks so I don’t know by how much.
