Use it at night IMO. Kinda lika a noise maker, white noise but a contant fan. Makes for a great sleeping device.
My fan is about 45W, this is about 8 and a noise maker is much less.<br />If a device is on 24hr a day, 365 days a week you're looking at about $1 a watt per year. So a fan on all the time would be about 44$ a year.
