I noticed that when I mount the cooler onto the CPU, the thumb screws included, are indeed thumb screws, so I cannot use a screw driver to tighten more than what I can tighten with my fingers. The manual, and online pictures show that the thumb screws included has a slot for a flat head screw driver, whereas mine do not. I find it difficult to tighten evenly to the motherboard as I can't fit my fingers in the slot to tighten further. So I think that might hurt cooling temps if I can't tighten with equal pressure on 4 corners.
2nd, do I leave the plastic in between the motherboard and mounting bracket?
