When I run Intel Processor Diagnostic Tool my idle temps are 40°C and after stress test it records around 59°C. Here is a temp difference of 19°C. Once a difference came around only 6°C(42°C to 48°C on load) and 9°C. But maximum times the difference is around 15°C . Is that normal for my brand new i5 4440 CPU? My room temp is very hot and humid..around 31-32°C.
