Could be better, but I think the general advice is to blow along the direction of the heatsink fins. You might need something with denser airflow.
in the field "user:pass" you should enter your login details to slush's pool? Like that "sampleuser:password123,sampleuser:password123" ? Not workers' details?
That is where you would put your worker details. sample_1:pass,sample_1:pass, use your worker info. You may need to set up a stratum proxy though, not sure if slush has getwork ports open still.
