I have a few questions to ask. I do not currently overclock but I wouldn't be surprised if I decided to in the future so I want my cooling to be decent. First quesiton. When I was installing my cpu, the stock thermal paste was touched leaving a fingerprint and a small corner scraped off. My temperatures are about 35 idle and 42 load and this seems decent for my processor (3500+). I have some arctic silver just lying around. Is it worth applying it? Or should I take Howard's advice that if it aint broke dont fix it? What about heat sinks? How much better would one of the cheaper heatsinks from thermaltake or zalman be over my stock cooling? A few of the sites mention a maximum recommended weight that the cpu manufacturers suggest for the heatsink. A lot of the coolers are over this weight. how much of a problem is this? Any suggestions are appreciated. Only one more, I swear. My motherboard is the A8N-SLI basic. I read a post somewhere where someone said that they had to flash the bios version from 1012 to 1013 to take full advantage of the speed of the processor. My bios version is currently 1009. Is there any benefit to updating the bios or should I go with Howard again? Thanks a lot for your help!
