My computer uses 1.5A-load, .8A-idle, .65A-standby, .05A-turned off on 125V. "The spaces between your fingers were created so that another's could fill them in."
i would go with the 7B
its pretty much the exact same but i uses 120mm fans instead of 80mm fans
120mm fans give you more airflow at less decibels which is all around good
