I've got one of those SilentBoost HSF (with the Hydrowave) and I can't agree that the noise output is 21db.
It probably 21db at 5v (silent) but not at 7v and definitely not at the stock 12v. It more like 26-31db at 12v which definitely not silent! Virtually ANY fan is quiet at 5v.
If you ask me, its all a marketing exercise to distinguish their products from other HSFs. The Silent Boost doesn't cool particularly well and neither is it particularly quiet at stock voltages.
You've been warned!
PS. If you're looking for the a high quality but quiet HSF, I'd recommend the Zalman7000. Its built for AMD and Intel now.
