I just ordered an Ivy Bridge i5-3750k that I'm going to pick up tomorrow to replace my aging core2 duo rig. My current HSF is a Zalman CNPS7000-AlCu that I've had for quite some time. I will be OC'ing the new CPU. Is the CNPS7000-AlCU up for the task or should I pick up something else while I'm at Micro Center?
