You're better off getting a controller with triggers that holds your phone like this

You are correct. No emulator. I have two controllers with fans, but they aren't the best of quality. The triggers are inaccurate, so I will be shooting someone then suddenly the trigger becomes unresponsive. The fan however worked really well tbh. The one in original picture doesn't have a fan. I have a desk fan blowing on phone.
