I am building my comp and was having some wierd reading problems with my asus a8n sli deluxe saying my panaflo fan 92mm was failing cause it was under like 1300rpm (figured might just be a bad read), but was installing windows and was hitting like 43C. Now that temp I know is not to bad for a 3700san diego, rather safe actually, just am wondering if it is this hot now, what about under a vigirous game? Any input? Using an XP-90C heatsink. At what temps where do I Start to get worried? I went through that stickied list but did not see 3700SD only the FX with san diego core. thanks.
