Re: orientation of hsf??
Position 2 is the most common, and correct way for most cases. Position 3 could be correct, as heat rises...it will be taking the air from down below and pushing upwards, towards the 200mm fan.
I don't know what you did with the thermal paste, but the best way to apply thermal paste, is to put a dot, the size of a grain of rice, right in the middle of the processor. Then you let the heatsink's weight spread it out, as you seat it on top.
