CoreTemp is reading the CPU core temperature, from the DTS on the CPU,and Asus is reading the temp collected from the mobo. Asus is BS, believe CoreTemp or Real Temp
. Those temps are high, but I don't know if the e6550 had temp monitoriing problems like the 86XX series. Read the info on the CoreTemp and especially the Real Temp sites.
Just in case you miss the link on the Real Temp main page Real Temp - Documentation
