How is the ventilation on the 520W ModStream? I've always had PSU with two fans in the past (Enermax) and wanted to try something different with my new build in a Wavemaster case. I was considering the PowerStream but don't really like the way the 2nd fan is located plus I read somewhere that it expels air out into the case (I might be wrong) also for anyone that has a Wavemaster knows that there might be some air obstruction in the back (see pic). I'm just guessing this as I don't know the actual dimension of the PowerStream. Plus I like the blue LED on the ModStream better than the green on the PowerStream
