for ur work any cooler will run fine passive . even while oced TRUE etc can handle 3.6ghz c2d easily with safe temps if u have good airflow in cabby .

but i would suggest u to get sunbeam CCF 92 / 120mm , it comes with fan controller , u can set the speed if u feel its noisy ...

TRUE is not available now and only Black edition is available which costs 3.5k .
