Ok, i recently built an AMD PhII 555BE system. Im running a 990fx Saber and a 9900 Zalman 120mm HSF. My temps are still at 41*c idle, and i cannot figure out how to turn up my HSF speed. OC'd to 3.9GHz, but still needs tweaking. I need to run Prime95, but am afraid with such high idle temps! Can anyone help with how to make my temps go down? HSF was way too expensive to perform like this imo ($58). As of now, i am running at an 18 multiplier and 216 FSB (3.888GHz to be exact), knocking my mem down to a 1400 speed range. I realize im new to OC'ing, but this just doesn't seem right. Arctic Silver MX-2 was used.
