AKM880 :
You could attach a small fan to lower temps, read the C2D and C2Q overclocking guide.
I have 6 X 180mm Intake Fans.
2 X 240 Extraction Fans.
Heat sink and fan on the 6gb of DDR3
Heavy duty Antec CPU heat sink and fan.
1KW PSU with Good extraction.
2 X GPU fans upped to 75% speed.
So, as you can see, plenty of air movement around a massive case. (Xclio Supertower).
(plenty of noise as you can probably imagine).
Think I need to go liquid.
