The mainstream 65 nanometer Core 2 Quad Q6600, clocked at 2.4 GHz, was launched on January 8, 2007 at US$851 (reduced to US$530 on April 7, 2007). July 22, 2007 marked the release of the Core 2 Quad Q6700 and Core 2 Extreme QX6850 Kentsfields at US$530 and US$999 respectively; the price of the Q6600 was later reduced to US$266. [2]
typical thermal power, which is measured under normal load (for instance, AMD's average CPU power) maximum thermal power, which is measured under a worst-case load; For example, the Pentium 4 2.8 GHz has a 68.4 W typical thermal power and 85 W maximum thermal power. When the CPU is idle, it will draw far less than the typical thermal power.

Thermal Design Power (TDP), also known as thermal design point, is the maximum amount of heat that a computer component (like a CPU, GPU or system on a chip) can generate and that its cooling system is designed to dissipate during normal operation at a non-turbo clock rate (base frequency).
These sensors, after being calibrated at the factory, are able to provide digital data concerning processor temperature information. The PECI bus , allowing access to this data from chipset components, is a proprietary single-wire interface with a variable data transfer speed (from 2 kbit/s to 2 Mbit/s).
Intel Core 2 is a processor family encompassing a range of Intel's mainstream 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single- die , whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module . [ 2 ]

If the applied mechanisms are not compensating enough for the processor to stay below the junction temperature, the device may shut down to prevent permanent damage. [ 2 ] An estimation of the chip-junction temperature T J {\displaystyle T_{J}} can be obtained from the following equation: [ 3 ]
