Quality of products #1 - Zalman coolers

Just installed a brand new Zalman's CNPS10X Optima on AsRock X79 Extreme9 motherboard and noticed two things:
1. While tightening the 4 main bolts of the cooler, and (very plausible) due to poor finishing and maybe bad design, there's a very high chance the user to create filings by the friction between the bolts and Intel clips (filings are barely visible with naked eye) that can SHORT-CIRCUIT the motherboard or other components during power on or working state!!! I was lucky to saw that before powering on the machine and to have a small magnet to collect them (I hope all of ...)
2. It's not possible to use closest to the cpu socket RAM slots (this particular motherboard has 8 slots) due to the cooler's inadequate design. They gave requirement that modules should be no taller than 44mm (mine are ~34mm with original RAM sinks, and can hit the cooler or its clips), while in fact the two possible positions of the cooler blocks modules with the cooler (especially if you lower it like in the user's manual recommendation to put some airflow and under the fins) or with fan fixing clips.

Great product, Zalman!
