Turntables fire, quality is normal, really quiet, as they said in the reviews. But my kit was a little wrong. Instead of the power supply wire of the unit (in the picture "G"), put in the kit there is one cable to connect the turntable to the unit. That is, for three turntables four cables to connect to the unit.
Pretty nice looking fans, still need to do some thermal testing. Wish there were more lighting modes but overall, happy with the product.
Though it may be weaker than fans with square edge, it looks freakin awesome. That's all it matters, isn't it?
