Sky Q box sounds like a dripping tap

So going back 2 years, I had a issue with my Sky Q box, so they replaced, as the fan noise got very loud, was 8 years old. About a week ago I got a next sky Q box as playback audio was cutting out and picture was glitching about 2 years old.. Now this newer Sky Q box with silver trim seemed fine, but at night it's sounds like a dripping tap . When off, I've noticed this sky Q box is different as it has a power pack and silver trim. Are they all like this now, trying to make us switch to Stream or have i got a bad box. My other 2 did not make this noise?

Sounds like a noisy hard drive. Some are louder than others

Yep, yet never herd a HD sound like that. Will report.
