How about Alphacool NexXxoS Extreme 2? It's 58 euros in Finland so its quite cheap, but how is it compared to the BIP 2 or PA120.2? BIP 2+2x 120mm Akasa 1400rpm->Alphacool NexXxoS Extreme 2+2x 120mm Sharkoon 1700rpm <--How much would my temps degrease? (Now in idle watertemperature is 31 degrees celsius and in stress 34-35)
