Pardon me, but I prefer the original by 1 million miles.

  let res = raw_api::query("SELECT * FROM Win32_Fan");
  for obj in res {
    if obj.get_attr("ActiveCooling") == Value::Bool(true) {
        if let Value::String(name) = obj.get_attr("Name") {
            if let Value::UI8(speed) = obj.get_attr("DesiredSpeed") {
                println!("Fan `{name}` is running at {speed} RPM");
            }
        }
    }
  }

If actually concerned about the need to know UI8, then create a typedef DesiredSpeedT or similar. This is equivalent to the struct Fan.

Edit: I understand the post is probably more of a playful exercise than anything else, but I really think the original is far far better (smaller, simpler, etc.) and hope that is not lost on people.
