The main difference is one has a green LED and the other doesn't, as well as the first one having a 4-pin connector and the second having a 3-pin. Also under the noise level the first one has "silent" and "normal" modes and the second one only has "silent." Does that mean the first one cools better or they just didn't mention the "normal" mode on the second one?
