Installed my new fan in a Ghostbusters Premium last weekend. Product and instructions were really great
However, and this is by no means critique, i was actually a little disappointed when i heard the fan activate. I was under the impression that it would be virtually silent with the backglass on. But that is not the case. In a quiet room, you still hear it quite easily when it comes on. It's still a huge improvement though, and i would easily recommend others to do it. But i just read several posts saying that you could not hear it come on, and for me that was not the case. But the sound it makes is a LOT less intrusive than the stock cooler.
Again, i hope this is not seen as a negative comment, but more as a "expectations alignment" for others (don't know the right word for it in english).
All in all - Excellent product, and really glad i did the swap!
