Yea that is not true at all. There is actually a very large equation to find out the decibel level.

Maybe you should go back to algebra because something raised to the tenth power is that number multiplied by itself 10 times. So 10 to the tenth power would be 10x10x10x10x10x10x10x10x10x10 which equals 10,000,000,000.

So don't tell me to learn physics when you don't know math.

Intensity level (dB) = 10 log10 ( I /10 to -12) so...lets solve this little puzzle once and for all! 65dB = 10log(Intensity / (10 to (-12)) I = (10 to (65/10)) x (10 to (-12)) I1 = 3.16 x 10 to (-6) Now...how many fans do we need to equal a jet engine @ 250dB? 250db = 10log(Intensity TOTAL / (10 to (-12)) I2 = 10 to (250/10)) x (10 to (-12) I = 1 x 10 to (13) SO... Intensity total / Intensity of 1 fan = Total fans 1x10 to (13) / 3.16x10 to (-6) = hahaha...3x10 to (18) fans!!! thats like a bajillion... 12000 CFM is = to that of a big fog machine... __________________ __________________ 3DMARK VANTAGE: 11,500 GPU: MSI GTX 260 @ 650MHz/1175MHz CPU: Intel E6750 @ 3.4GHz/1.33v/60c HSF: Arctic Cooling Freezer 7 Pro MOBO: MSI P6N SLI-FI 650i RAM: G.SKILL 3x1GB DDR2 800 SND: Creative Audigy 4 SPK:Logtech X-540s MOS: Logitech MX600 Wireless Laser LCD: HANNS-G 28" Widescreen
