700 Watts Cooler Master Silent Pro

Asus Crosshair V Formula MB

4GB DDR3 1333 XPG Gaming V2 

FX 8120 3.1Gh with Stock Sink and Fan

Case with 6 fan 2 out air  4 in air

Programs Used  Core Temp, HWInfo64, AI asus program, Bios Temp


Ok I allready checked the MB with an X6 phenom II Prossor and temps are ok, or just in the base line, but with the FX 8120 BE 3.1Gh the sensors are diferent.

1.- All system at Stock mode, never OC or even changed base settings on mother soft or Bios, I buyed the Prossesor last week.

2.- The Core Temp shows me IDLE Mode 23°C in AMD 10th+ CPU Thermal Sensor.
3.- The FULL CPU IDLE  mode shows 41°C at the  ITE IT8721F Sensor

4.- by searching internet the AMD FX8120 Max Temp supported is 60°C and almost all programs shows me the ITEIT8721F temp. rates as the principal temp sensor.

5.- but the cores i mean, The CPU#0,1,2,3....,8 shows the AMD 10th +CPU Thermal sensor temp. rates. = 23°C

6.-When I play BF3, Sleep. Dogs, or any other Game in normal mode my temp. rises to 63°C  ITE IT8721F Sensor and all programs shows the alert but my Core Sensor "AMD 10th+ CPU Thermal Sensor" shows 52°C, with the X6 Phenom Prossesor the max temp was 45°.


All this in Stock Mode with the Prossesor default Fan.


1 .- So, wich is the real Temperature, I Know all this sensors are not exact but are them ok? or I should return the FX8120 to my dealer and apply for Warranty? I am from Mexico so maybe terms are different. 

2.- I know i should try to buy another cooling System but searching at some forums, some guys said the wrong temps are a bad FX sensor manufacture and are wrong, some ones are displaying too low temps and other to high temps.

3.- it is suposed that core temp and socket temp should ll been the same with a minimal dif. but the same. and mine are not.

4.- I ask again is this normal? are the sensors wrong, I should return the Processor? or I can keep it but change my cooling system (I'll buy the H80 is this a good choise?) 

5.- if the sensor neither the cooling system were the problem what could be?


Thanks and sorry my English, It is not my native languaje.
