I just bought a pentium 631 and installed it. But I had a problem, my mother board has these screw holes where the stock cooler gets screwed to and the pentium cooler just didnt fit. I did not try to remove these screw holes for fear of damaging the motherboard. I would like to know if there is a way to remove them since I believe that the stock cooler that came with the motherboard might be less effective than the intel stock cooler. I'll post pictures if necessary, thanks in advance for any replies.
