25 degrees C I hate you. I'm not offended. I know this sounds totally crazy. All the fans are running and they scroll up as the temperatures rise. I'll check the settings though - haven't done that yet - never had to before. Yep - have done that - all fans running. That's next - thanks for the suggestion. UPDATE - set all fans to 100% in the bios - can hear them whining. Ran a Norton Full System scan (perhaps surprisingly a very reliable heat trigger) and within about 30 seconds 3 of the 4 cores maxed out at 100C and one was much cooler, maxing at only 95C. Something is horribly wrong. Upside is I've knocked 5C off the idle temps.
