My processor is an AMD Atlhon 64 X2 Dual 6400+. Ventilation isn't an issue, I have an open-sided case with plenty of fans and this hasn't happened before. I'm nervous because the official AMD specs say that the maximum temperature should be 63C, but other posts around the web have people saying that 65-70 is fine, some even saying they constantly max out at 75 or over with no problems; I was hoping to get a non-partisan opinion.
Also, I recently upgraded to the ATI Radeon HD4870, specifically this model, http://www.newegg.co...N82E16814102825 . Would that thing's extra power and heat be directly affecting the CPU? Especially since the sound card (SoundBlaster Audigy SE) is in the slot next to it, partially blocking about 1/4 or 1/3 of the fan? There's still at least half an inch or so of space between them.
