Full-tower computer cases may contain multiple cooling fans. At the top of the case is a fan controller. Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they ...
Coolers typically run on power drawn through one of the laptop's USB ports, with some models featuring integrated USB hubs so as not to consume one of the laptop's often limited number of USB ports. Some active coolers draw heat from the underside of the computer; others work in the opposite way – by blowing cool air towards the machine.
A small blower fan is used to direct air across a laptop computer's CPU cooler. A case fan may be mounted on a radiator attached to the case, simultaneously operating to cool a liquid cooling device's working fluid and to ventilate the case. In laptops, a single blower fan often cools a heat sink connected to both CPU and GPU using heat pipes.

There are a number of other companies (AMD, Microchip, Altera, etc.) making specialized chipsets as part of other ICs, and they are not often found in PC hardware (laptop, desktop or server). There are also a number of now defunct companies (like 3com, DEC, SGI) that produced network related chipsets for us in general computers.
In order of model number: i7-3820, i7-3930K (six core) and i7-3960X (six core). Sealed liquid cooling units for the processors came factory installed. The R4 is the first to use quad channel memory and has Dedicated graphics card options including AMD Radeon HD 6000 series and Radeon HD 7000 series as well as Nvidia GeForce 500 series .

XPS M140 (Late 2005) – The lower-end model XPS computer that has a chassis identical to the later Dell Inspiron E1405 laptop. This model features a choice of several Intel mobile processors, a 14.1-inch widescreen and between 512 MiB to 2 GiB of RAM. This model, being more media-oriented than gaming, does not feature a dedicated graphics card.
