Brisbane temperature readings

[SneakyStuff]

I was wondering if it is a wise idea to use the cool and quiet operation in my BIOS after reading that many brisbane core X2's report false temperatures that are lower than the actual temperature. Does 22'C sound too low for a non overclocked X2 4800+ under no load? I don't want to end up frying my CPU by slowing down the fan under false circumstances!

So you're idle temps are 22c? What are your ambient temps? I am idling @ 30c right now on my Brisbane G2 based 5000+ BE, you should only be worried about your load temps and even then only when it gets up to 90c+ (this is around the rated Tjunc for most modern CPU's).

Go ahead and run Cool & Quiet. Your system board and bios are likely to know what to do. Plus most modern cpu chips will throttle down as they approach excessive temperatures. Plus you are not overclocking, and these chips run cool at stock voltages and speeds.

Temperature monitoring software may read the wrong signal, or may not know how to calibrate the reading. Sometimes an offset is required.

CoreTemp 0.96.1 is at -10c -11c at idle for one Brisbane X2-4000, another one idles at +9c +10c. Same board, same chip stepping, same 20 degree workshop, one cpu packaged in China, the other in Malaysia. Whatever version of Speedfan I have on that pc is also giving incorrect readings.
