I would go with this Scythe instead - http://canadacomputers.com/product_info.php?cPath=6_108&item_id=039968
Same price as the one you linked but has more information like RPM and temp if needed. Also has 1 Amp per channel. Just hook the 3 pin fan connectors straight into this fan controller. You don't have to worry about using that adapter anymore. And if you get that Megaflow in the future it shouldn't have any problems with this fan controller. Megaflow is rated at 0.16 A (Max 0.28 A).
