uses 65Watt max. When ur surfing its maybe only 30 oder 40Watt.
btw it often depends on ur Mobo how exactly it shows ur temps, cuz although the cpu has a temp diode inside u still need a good mobo that can actually read the information from the temp diode. Many boards have their own sensor very close to the cpu slot only. This also includes that the mobos temp sensor is not allways showing correct numbers. Some boards tend to show higher temps, sometimes u can fix it with bios-updates.
