Socket AM3 is a CPU socket for AMD processors. AM3 was launched on February 9, 2009 as the successor to Socket AM2+, alongside the initial grouping of Phenom II processors designed for it. [1] The sole principal change from AM2+ to AM3 is support for DDR3 SDRAM. The fastest CPU for socket AM3 is the Phenom II X6 1100T.
A CPU socket is made of plastic, and often comes with a lever or latch, and with metal contacts for each of the pins or lands on the CPU. Many packages are keyed to ensure the proper insertion of the CPU. CPUs with a PGA (pin grid array) package are inserted into the socket and, if included, the latch is closed.
AM3+ CPUs are not mechanically compatible with AM3 sockets as AM3+ CPUs have an additional pin that the AM3 socket can not accommodate. Another issue is the use of the sideband temperature sensor interface for reading the temperature from the CPU. Therefore, some CPU PWM fan headers may only run at full speed.
Phenom II is a family of AMD's multi-core 45 nm processors using the AMD K10 microarchitecture, succeeding the original Phenom. Advanced Micro Devices released the Socket AM2+ version of Phenom II in December 2008, while Socket AM3 versions with DDR3 support, along with an initial batch of triple- and quad-core processors were released on February 9, 2009.

A fan controller with LEDs indicating fan status and potentiometers and switches to control fan speeds Another method, popular with PC hardware enthusiasts, is the manual fan speed controller. They can be mounted in an expansion slot or a 5.25" or 3.5" drive bay or come built into a computer's case.
In addition to the CPU drivers offered by AMD, several motherboard manufacturers have released software to give the end user more control over the Cool 'n' Quiet feature, as well as the other new features of AMD processors and chipsets. Using these applications, one can even control the CPU voltage explicitly. PhenomMsrTweaker (SourceForge link)
The AMD Phenom family is a 64-bit microprocessor family from Advanced Micro Devices (AMD), based on the K10 microarchitecture.It includes the AMD Phenom II X6 hex-core series, Phenom X4 and Phenom II X4 quad-core series, Phenom X3 and Phenom II X3 tri-core series, and Phenom II X2 dual-core series.
The AMD 900 chipset series is identical to the AMD 800 chipset series except for the fact that it is only found on Socket AM3+ mainboards, whereas its predecessor is only found on Socket AM3 mainboards. It was released in 2011. This allows consumers to easily identify the Socket through the chipset name.
