Yeah that tracks - Along with blowing it out and pop off the rear filter cap and gently brush the fan vanes - hair and fuzz can wrap around the impeller and slow it, which a quick vacuum won’t always fix. If you use a concentrator or hold the intake near your hair or a towel, take the nozzle off for bulk drying and keep the intake in open air to avoid recirculating hot exhaust. Also skip thin or long extension cords; voltage drop can slow the fan and make it trip the thermal limiter sooner.

Sounds like a classic case of a stubborn device. These things can be finicky with their batteries, especially if they've been left unused for a bit. Start by ensuring it's at a comfortable temperature, not too hot or cold, because that affects charging. Force a restart with a prolonged power button hold, around 30-60 seconds, and if there's a reset option, use that sparingly. Try charging via a computer to see if it registers at all. I actually tried that and it fixed everything but then... yeah, turned out the original charger was faulty, so test with alternatives. If it persists,, might be a deeper issue like a worn battery, so professional help could be next. Don't give up yet though.

I would go with HelloBaby baby monitor for a two-story home. Its dedicated non WiFi link is typically reliable through floors and kitchen walls, the 1000 ft rated range gives you plenty of cushion, and the battery can last up to 30 hours so you are not tethered to a plug and plus the night vision is solid.

High frame rate or VRR can change how the TV renders frames which sometimes throws off audio timing only on the console input. Make sure the TV applies Game Mode to that HDMI and turn off motion smoothing noise reduction, and any film mode. Those add a lot of latency and can push the audio late when ARC is in the mix. Once the picture path is lean, set TV audio to Passthrough and try console PCM. Keep the bar simple with no virtual surround. If you can only get close, use the TV lip sync slider to delay the video slightly to meet the sound.
