I've been working on my home lab for quite a few years, and I've reached a size where I am starting to have some issues I never really considered before. Note: I'm in North America.

1. Power - I have a 20A dedicated circuit for my servers, and I'm reaching the limits of that circuit.

2. Heat - Average power use on my server power circuit is about 14A. That's a lot of heat, especially under load.

3. Noise - There is a constant hum of servers everywhere in my home. Even on a different floor on the far side of the house, you can hear the servers doing their thing.

I need more upgrades, but feel I can't due to the items above.

How did you solve your heat/power/noise issues?

I'm considering adding a mini-split AC and a sub-panel, but those things might be overkill for my closet.
