The Hydor only makes an audible click when it turns on to begin heating the water. Other than that it's flawless if you follow instructions on how to properly install it and use it.
If you're seriously considering buying one; Drs. Foster & Smith is having a sale on them with the cheapest prices you can find. And if you're a new customer there; PM me before buying and I'll give you a $10 coupon you can use (it only works with new customers and unfortunately they sent it to me after I made my first purchase with them).
