how much difference is 32 dBA compared to 28

post #1 of 6
Thread Starter 
hi i got a question regarding fan noise

i bought these 2x blademasters http://www.coolermaster-usa.com/product.php?product_id=2945 a year ago and i was wondering how much quieter are Scythe GentleTyphoon ap-15 http://www.newegg.com/Product/Product.aspx?Item=N82E16835185092&cm_re=gentle_typhoon-_-35-185-092-_-Product?

supposedly blademaster are 32 dBA and the ap-15 28 dBA

Would i notice a big difference or is it not even noticable? Im using the blademasters on my H50

the way DB works, yes, it will be noticeable although there are other factors to consider like the pitch of the noise the fans make

Nearly unnoticeable, but some companies tend to straight up lie about fan specs. So, those CMs may be noisier than stated, while the Scythes are likely true to spec.

Just speculation, though.

Edit: And yeah, as the others said, pitch is the biggest factor. I've had some fans that were very quiet, but I could just barely make them out between my other fans since they were a slightly different pitch, and they were rather annoying.

As a general rule, a 10dB increase will sound twice as loud. But depending on the frequency of the noise it may or may not be more intrusive. For example the low pitched sound of larger fans are less intrusive than the high pitched sound of smaller fans.

For case fans I think anything under about 35dB is acceptable, under 30dB is great.

The gentle typhoons will be a lot more quiet since coolermaster lies out their ass about fan specs. They quote the noise at the lowest speed the fan can spin and the CFM at the highest speed the fan can spin and pretend it can do both at the same time.
