Cooling for my Corsair 200R?

[Renegade23216]

I'm going to buy this case. I'm using an i5 with integrated video. So it won't generate much heat (no video card). Is the case default cooling sufficient or should I add any case fans?

Is it also advisable to use Arctic Silver 5 for my i5 or is the included OEM thermal pad fine?
