If you aren't planning on OC'ing I say leave the thermal pad on. It's made to cool that cpu within reasonable temps running at that stock speed. Yea, the artic compound is a good deal better and if you do wont to put it on you should be fine. It will be hard you screw up the HS. But I do believe if you remove it, it may void the warranty. Install everything out of the box like it is and you will be sure to have that 3 year warranty that you paid for if you bought the retail processor.
