Albatron PX865PE Pro II CPU temperature readings

Question

My Albatron PX865PE Pro II mainboard with Pentium 4 2.4C with retail HSF installed shows CPU temperatures of 48 degrees Celcius when idle and 67 degrees C max after running cpuburn for quite some time. The lowest I've seen is 47 within a minute after turning on the totally cooled down PC. When I turn off the PC and measure the temperature at the top of the heatsink, it does not get above about 28 degrees C (it takes some time to get there). Are there others with this mainboard who have the same readings, or who do get normal readings? Eddyproblema de audio
