How loud are these things? Could you put one in a bedroom without regretting it?

Only if you’re as good as deaf.

If you like sleeping with white noise, you’d be ok with 1 or 2 in the bedroom, but stacking more than that would compound the decibels. I have a dozen running inside the home (not counting what’s in the attic), all placed in rooms that aren’t normally occupied, and I don’t notice them when watching TV, but can hear them when all else is silent and I’m at my desk (sounds a bit louder than when a fridge is cooling). This is without a single door closed to block noise, since I want the mining heat to help warm the home. If I shut doors, all ASIC noise vanishes. G1-minis are far more home friendly than the G1, which is worse than the loudest vacuum cleaner running at all times.

I removed 2 inflow fans of each miner, put them naked now, the noise is reduced a bit. However, it’s not suggested to keep them in bed room, not good for mental health and hearing.
You may isolate noise with wooden room/door.

I am curious as to why you say white noise is bad for mental health?
I have hella white noise around 24/7 and enjoy it.

I slept once near my G1 mini, and yes, I did not sleep that well. White noise is not much of an issue, it is just about the intensity/decibels, and a G1 Mini is rather loud. With a door between me and the G1 mini, the sound is muted enough to sleep properly.
I hope that in the G2 mini (assuming there will be one made at some point), they put larger 14 inch fans which are more quit. Or perhaps just just give silent fans as an option for additional pay.

Every time I mention this it is ignored but I’ll say it again anyway.
To reduce noise on your G1 mini, first enable SSH in the web config under System → Administration and log in via terminal. Then type the command ‘nano /etc/config/cgminer’ and scroll down to the pwm settings where you can adjust default (60% preset) and max (100% preset) fan speeds. Hit ctrl+s then ctrl+x and then reboot the miner and keep an eye on the noise/temp ratio.

Did you do this and did the temperature stay low? I had some of the early batch G1 Mini miners and they burned through quite quickly. I think because they were running too hot.
In the newer version, the ones most people have, they made the casing bigger and perhaps changed settings to throttle at lower temperature, but of that I am not certain. So it would good to have it confirmed that after this change none of the G1 Mini’s stopped functioning because of getting damaged by overheating.

I tested a while back just keeping the fans at 50% with an alarm level of 85C and it never reached high enough to shut down. Here’s the relevant section of /etc/config/cgminer at its default levels:
I do keep 4/6 miners in a forced air cooled cabinet so I run the fans full speed. Also my server racks are definitely louder than my miners.
