Cards run 30% cooler and quieter as well as Asic resistant.
yes script machines can mine keccak, and they do run cooler, not sure about asic resistant because if a asic script can mine script, and a script card can mine script, whats to stop a asic script from mining keccak?
You need to read up on what asics actually are and how they work. A scrypt asic will never be able to mine keccak properly. You would need an asic specifically designed for keccak, 'application specific' = asic designed to do only a specific task.
