I have been wanting to overclock my E7400 (2.8 Ghz) for some time now, but as a first time overclocker, I'm not sure if I have enough cooling to keep it stable. My case has a side panel fan and a rear fan, both 120mm. When I ordered my stuff, I didn't think about buying any extra cooling so I'm using the stock heatsink, and I picked up this http://www.bestbuy.com/site/olspage...ermal&lp=1&type=product&cp=1&id=1075583463530 from best buy. Would it be safe to try and overclock with this setup?
