Q: I am planning to buy a "SilverStone Nitrogon NT06-Lite" cooling block. Do I need to buy an addition fan? http://specialtech.co.uk/spshop/files/detail/nt06-lite-v2.jpg
A: having a fan bringing cool air into the case facing the heat sink will help keep it cooler but this is a fan less heat sink so no fan is really needed
