Ordered this unit a couple of weeks ago. On first use it was completely silent, but since then the fan has developed a constant, high-pitched whine. It’s genuinely uncomfortable to listen to and is clearly audible even during quiet scenes in movies.

Is this level of fan noise normal, or does it sound like a faulty fan that should be replaced under warranty?

Video was recorded when the projector was off as it randomly turns on for a couple of seconds during the night waking me up. But the noice is the same as when in use!
