Welcome to the Community, I'm really sorry to hear that your TiVo box is being noisy. I'd like to take a look at this and run some tests on the box from our end but I've not been able to accurately locate your account unfortunately.
If the sponge pads that ozsat has recommended haven't done the trick, respond to the private message I've sent with the requested information and I'll take a look as soon as possible. You can view the message by clicking the red envelope on the top left of this page.
Sorry again for the inconvenience this is causing, we'll talk soon
