we have similar fans....look at my pics. the direction of airflow is pretty obvious. remember to have more fans pulling in air than out.
also in your bios you can adjust fan settings, have it on turbo or to max @60*c.
I really think your overclocks are hindered by voltages and maybe some bios settings not being right.
google search everything to do with overclocking and read till your eyes hurt (heard that somewhere else lol)
