For the case fan, a Vantec Stealth, Panaflo, or SilenX are all good choices.
For your heatsink, the Zalman is very good, however, if you plan on overclocking, you might wanna look towards Thermalright. Their XP-120, XP-90, and SP-97 products are really good. The Zalman isn't the best when it comes to OC'ing.
