if i have a 34dB-A noise fan and 2 25dB-A noise fans

would the total noise lvl be the 24+25+25?

or would it just be 34, as the louder fan shadow over the 2 quieter ones? thanx, bye.

It's definitly not 35+25+25.
Some member posted up a program which calculated the noise level for different fans in different place.
I think your noise level would be under 4dB's.(me thinks)

doesnt work like that.

There is a forumla for Db's and from memory yours wont go above 40's

Unless all fans are working at exactly the same frequncy and wavelenght.

ok i worked it out using that dos program on http://www.overclockers.com/articles607/

and i got 3 fans, 34.5dba, 25dba, 25dba, all oprating at 100% speeds

the program says it will be 35.3792dba in total, which is not to bad and hopefuly my tmpe will drop by 5C with these 2 new case fans.

also finders crossed that they r the same (almost) frequency
