Uh-oh! That one site describes the bearing type for the Blade Master 120 as "Long Life Sleeve." Scott, there's no doubt in my mind that you would prefer case fans with ball bearings.
You got it!
Would you really prefer that a case fan plug directly into a motherboard, or is it OK if such a fan utilizes a power-supply connector?
I prefer a fan that plugs into the motherboard if the motherboard has the ability to control the fan speed. That is often done via a 4-wire connector (the 4th wire controls speed), but some 3-wire motherboard fan connectors can control speed by varying the voltage supplied to the fan. Bottom line: If the BIOS Setup has no case or chassis fan speed settings then there would be no difference in using the motherboard or PSU connector for the fan. Scott.
