Their specs don't list precise dB numbers, but it promises 'whisper quiet' on all speeds. A retailer near you might have a sample piece to try out.
To my ear it sounded maybe ~20dB on high, not whisper quiet but definitely something that wouldn't disturb your sleep. Magnitudes quieter than the 6990 fan on 50%.

Do you know the dba on that fan? Curious as I might pick one up.

I run cards in a dedicated place with ventilation so just default fans..
If you run these at home you will *need* extra fans blowing air on the cards if you want to actually live in the house.
(Well.. Even if you put them in a basement, many cards next to one another will still run very hot)
The fan noise of these cards at 100% is absolutely unbearable.
Actually measured ~85dB with a professional Extech decibel tester a few meters away, which is not that far away from a small jet engine.
Anyway, if you want to cool a ton of rigs at once, try these. They are very power efficient for the amount of CFM provided.

Home Depot, Costco and some other big retailers routinely carry these in their inventory.

I have 2 6990 in one rig and am using 450 cfms blowing directly on them from top. i leave fans on auto with this... runs quieter than setting 6990 fans to a higher constant rate.
Sorry, but it would be about 250cfm.
you didn't actually link anything.....
Assuming it's a fan, if so yes
I have one pointed at mine and works well ~10C drop

Hi,
I have 3x6990's in a haf x case in which the side fan facing the cards is not powerful enough. I am thinking of replacing it with something like this... Would it be ok to blow air at this force onto the cards?
Thanks.
