Your temps don't look right....might be the calibration on the interface or it might be giving you good data.
Is your fan spinning? What is the ambient temperature? What kind of PSU are your running?
What is on 47-48 C not right?
Mine is running between 40-43
This is depend on the ambient temperate, mine running all at 49-52 C after OC really well, with 400Mhz and 393Mhz.
