Dude,

It's rated at 55db. I'll have to pass.

Thanks,

Very impressive fan. Very quiet too, for what it does. 55db is nothing to overclockers. Don't forget, with a reduced speed, this thing would be nearly silent inside all the MDF we use, and still whip any 120mm fan I've seen.

A word about SPL, it is measured at one meter, usually. The further away, the quieter it is. At the quietest moment in your dwelling, you seldom will be able to get less than 40db on a metering device.


160 dB SPL immediate ear damage
150 dB SPL jet airplane at takeoff
140 dB SPL large caliber pistol shot (10 meters)
130 dB SPL threshold of pain
120 dB SPL loud rock concert
110 dB SPL typical large club
100 dB SPL loud theater
90 dB SPL threshold of comfort
80 dB SPL neighbors complain about your stereo
70 dB SPL conversational level (1 meter)
60 dB SPL quiet conversation
50 dB SPL average home interior at night
40 dB SPL quiet auditorium
30 dB SPL whisper
20 dB SPL quiet studio
10 dB SPL gentle rustle of leaves
0 dB SPL threshold of hearing

The point is that the refrigerator is making more noise than your projector, even if you use this fan full speed. Of course you're not sitting under/beside your refrigerator though.

Well, at least I was half right, you're not under the fridge.
