I will pay you £500 if you take my CAAD away and make it not creak or rattle, and stay that way for as long as all the other bikes I've ever built have not creaked and rattled, which is forever. If you honestly think you can make a BB30 stay un-creaky until the bearings fail, then you must be some kind of wizard or magician. It's complete pot luck, largely dictated by the experience that BB30 creaks. Full stop.

As Howard says, it's a standard designed for good/race bikes that will be maintained well.
I killed one BB30 bottom bracket in 86 miles - the Ride100 that was the wettest ride I've ever done.
Therefore of course you can kill it if you abuse it, but if it's been installed properly it won't suddenly "go wrong" through normal use.
I'm not currently wearing a pointy hat with a rabbit up my sleeve but I've never had a BB30/PF30 bottom bracket that I could not (ironically by changing a QR or a pedal) render totally silent with a bit of thoughtful maintenance.
