Hey dude, just got one of my Inno3D cards in and the silence is blissful
With my system at idle the case fans are running 7dB, the roof rad fans are running 8dB and the PSU fan and front rad fans are off, I can slightly hear the GFX fans, but it's not loud enough to annoy and more importantly the tone is infinity better than the Galax fans which I think was more of an issue than the volume anyway.
If I spool my roof radiator fans up to full speed (800RPM) they completely drown out any idle noise from the GFX fans, and these fans are rated at 11dB so that should give an idea of how quiet the GFX fans are at idle.
As for the card itself I am blown away, I can't believe these [originally] cost the same amount as Galax blowers, the build quality is in a completely different league, the silver parts of the cooler shroud are metal not plastic, the card itself is noticeably smaller but heavier too due to the more substantial heat sink, it has a sort of armour type metal sheath over most of the PCB and it's visible that the chokes are perfectly aligned and normal sized (something to note for the future. Plus each card came with a copy of 3Dmark and a gaming mouse mat :O
