I'll consider writing Silverstone....

As for fans that push 110CFM +-5%:
San Ace 1011 (yes, it's rated at 103, all four of mine pulled between 112.1 and 114.5)
Panaflo U1A (rated for 114.7, one pulled 113.0 and the other 112.7)
anything that Delta rates at 110CFM +-5% (even their 220CFM beast got to within like 1CFM of rating....our data corroborates on every fan so far--I trust their CFM and dBA numbers completely)
anything else that NMB-MAT rates at 110CFM +-5% (the Scythe Minebea series was tested to within .5CFM on all models in my testing....and the Panaflo NMB-MAT fans are also within 3CFM on all 10 I've tested)
