I already have one CM excalibur 120mm fan on my Antec Kuhler as a push/pull on the radiator but the antec fan that i got with the cooler is very noisy, was looking at 2x Scythe gentle typhoon to replace both fans on currently but its a bit expensive for case fans. So was wondering would there really be such a huge temp drop going over to gentle typhoons or just getting another cm excalibur fan?
