Pros: Very low volts, Overclocks Decent, Looks
Of course, lower voltage means less heat, and also gives a bit more headroom for overclocking. Currently I'm running stock at 1600mhz, but was able to get them to 1866 with just loosening the timings up a bit to
10-9-10-28 and bump the voltage to 1.5v . Was nice and stable through intel burntest on extreme.
The heatspreader design is pretty nice looking too. Simple black is what I like. Rather low profile too so its great for anyone with heatsink clearance issues.
