3 wires out of case? are they 110ac fans or 12v dc fans? I recall (shrudder) my first 120mm front fan, it was an 110ac monster that sounded like a dc9 on take off. I got edumencated (j/k) and switched to 12v dc 120mm's and threw a reostat on them for controll. Now they sound nice and quiet at half speed, but can open fire for quick heat venting.
