Is Xigmatek a good brand of fans? I didn't hear anything about them when I was fun hunting, and I already bought some slipstreams. However the Xigmatek 120mm fans on newegg look like they have a nice cfm / db ratio.Although I know those are almost always a lie. Slipstreams do move more air at a lower RPM it looks like though... The reason I ask is because I might be needing some 140mm fans and xigmatek looks like the only good brand that has them on newegg.
