Pros: I loaded my antec 300 case with 3 of these babies, they work quietly and efficiently as intended. i read some reviews that said the fan control didnt work, i have had no problem with the fan control out of the 3 of these i installed.

Cons: nothing yet

Overall Review: i wish you could combine the 3/ whatever number of fans you have to the same control knob, to save pci ports.
