As is the case with most, my miner cannot stay in the house due to noise. I've seen where people have them in basement or in a garage. Any issues with insects or humidity and the S5? I've got a detached garage that is not climate controlled, and I'm pretty sure I need to move it out there.
Shouldn't be a problem but if there really are insects consider putting a bug screen on the fan. This will reduce airflow somewhat but might be better than having the heatsink clogged with dead bugs.
