Best 120x120x25mm fan that can deliver 70 CFM???

Update: Still messing with my new sys. The sys as a whole has amazing frame rates in games, but the PSU is a little noisier than I originally anticipated. I am at the point where I think I am going to pull it apart and mod it.

Researching it, there is an ADDA fan in this thing that puts out 85 CFM @ 39.1 dba @ max speed of 2200 RPM. This is a little too loud for my blood, even though it isn't terrible. The box on the Silverstone states 24 dba minimum but at lowest speed it is more like 30 dba before ramping up to the 39.1 dba at the max speed of the fan (So where did they get the 24 dba number from? Advertising gone wrong again)

So the question is, who makes a 120mm x 120mm x 25 mm fan that delivers about 67-70 CFM (I want to stay within 80% of the CFM of the original ADDA that shipped in the Silverstone PSU) and is relatively quiet? I anticipate this will be somewhere around 1600 to 1800 RPM and the max db output should be around 30 dba. This also means that the normal op of the PSU should have a db output of somewhere around the high teens to mid 20's.

I've found a company called Globe that makes one in the range I am looking for, but I can't find where they are sold!!! Ahhhhh!

Anyway, any help you guys can offer would be appreciated.

Thanks,
