These fans do look nice and push a lot of air but my biggest problem is that they are Molex fans. In this day and age, there should be no reason to have a Molex fan. I doubt it would cost much more to swap it to a 2 or 3-pin fan connector. Even if it didn't support PWM that is fine, just make it the standard connector, not Molex. But besides that, these work great for the price. A little loud but not too bad (them being loud is being its a Molex fan).
