whats the db rating of the fan?

Wow, that's a tough question. I have the fan mounted on a radiator on my little airplane. I actually do not hear it run as I'm flying with a headset on. I do know that when I run it while the plane is in my hangar, it really is rather quiet running. I'd have to guess that a db rating would be in the low range. perhaps 40 or so.

I have not measured the volume in dB, However it is much quieter than the case fans and CPU fans. I currently have it in my workshop in an open air environment, so I never hear the thing. The fan is 140mm I believe, and is controlled by temperature. The intelligent fan control keeps fan noise to a minimum below 45C. Which it never reached, even while mining in the summer. Regardless, it will be a very quiet unit for most applications. Look for the review at Johnny Guru for more info. -buzznut

Don't know the db level but I can say you can have a normal conversation when it's running. Really quiet for a compressor. I'm very happy with it

I haven't noticed it over my other case fans (3 for the case and 2 for the H100 cpu cooler). But looking at a review over at TechPowerUp they had the it maxing out at about 55db. I too use headphones.. so there is that. Here is the review if Amazon will allow the link. http://www.techpowerup.com/reviews/EVGA/SuperNOVA_G2_1300/6.html

I don't know. All I know is that it's an excellent fan for me here in the U.S. Sorry I can't be of more help!

I don't know the actual db. rating but I would say "not bad, wear hearing protection indoors" I have found the sound less and lower pitched on softwoods, higher pitched with hardwoods. About the same level sound as a router while cutting.

I have no idea, since I have only this version. Perhaps you could print out the features and specifications of each fan and compare them that way.

When 640's fan get to around 60% it gets pretty loud. 3 rd part fans MIGHT reduce the sound because both could spin at a lower rpm. The sound produced when its not doing much is not loud w/ just a stock fan IMO.

It's pretty loud. Manufacture specs say 50dB, I'd say that just about right. It's about the same noise as one of the old box style fans.

I run it on f2 and it is not any louder than a normal fan. F3 is a little louder but no need to run it on f3. I forget it is even running.

Mine is rated the same and it seems to be working fine though I never really play at high volumes. Great speakers

This fan is absolutely quiet when running. In fact, I have had to go up on the roof to make sure that it is running after the last hail storm (it was OK). Very high quality unit. I don't know about Sone ratings, but I suggest the 30 watt over the smaller one. Hope this helps!

I measured 86 dB right below my fan on high. Belt drive is supposed to be quieter. Higher quality is quieter too, but much more expensive.

I don't have a hard number on the sound rating of this fan, but I am happy with its performance in my garage. Standing right under it you would be able to hold a conversation with somebody close to you by raising your voice just a bit. At the lower speed setting the sound drops probably about 6 to 10 dB and the conversation would be fairly comfortable.
