After buying my radeon 3850 a month ago, a fan in my computer sometimes goes really loud for a few seconds while gaming. At first I thought it was the radeon 3850, but after using RivaTuner, the sounds were different. Because it is the only other fan in my system, I have reached the conclusion that it is the CPU fan that is going 100%. My question is: since my comp is a HP, does the fact that the fan goes 100% mean that the CPU is significantly overheating? If so, should I need a new CPU fan? And if that is also true, then what fan would you recommend? Thanks in advace
