i know similar questions have already been asked, but, for my rig, with only limewire, aim, and internet explorer running, my cpu temps were 54 and 56, and in my bios my fan settings are Fan Detection Disabled, Response Aggressive, and Dampning Normal and it is in a 4 pin. room temperature here is normally around 60-70 degrees. are these temps normal, should i be worried? is there anything else i can do to try and lower the temp? should i consider buying a new heatsink and fan? maybe changing the thermal paste?
