A computer fan is any fan inside, or attached to, a computer case used for active cooling. Fans are used to draw cooler air into the case from the outside, expel warm air from inside and move air across a heat sink to cool a particular component.
The Pentium 4 was a seventh-generation CPU from Intel targeted at the consumer and ... Model SL7E4 has an unattached fan heatsink. Some Socket 478 models ...
This can provide increased system stability in high-heat environments, or can allow a system to run with a lower airflow (and therefore quieter) cooling fan or without one at all. For example, a Pentium 4 processor normally clocked at 3.4 GHz can be "underclocked" to 2 GHz and can then be safely run with reduced fan speeds.
Fans are used when natural convection is insufficient to remove heat. Fans may be fitted to the computer case or attached to CPUs, GPUs, chipsets, power supply units (PSUs), hard drives, or as cards plugged into an expansion slot. Common fan sizes include 40, 60, 80, 92, 120, and 140 mm. 200, 230, 250 and 300 mm fans are sometimes used in high ...
Also based on the Northwood core, the Mobile Intel Pentium 4 Processor - M [26] (also known as the Pentium 4 M) was released on April 23, 2002, and included Intel's SpeedStep and Deeper Sleep technologies. Its TDP is about 35 watts in most applications. This lowered power consumption was due to lowered core voltage, and other features mentioned ...
The force from the load plate ensures that the processor is completely level, giving the CPU's upper surface optimal contact with the heat sink or cold-water block fixed onto the top of the CPU to carry away the heat generated by the CPU. This socket also introduces a new method of connecting the heat dissipation interface to the chip surface ...
The processor executes the SMM code in a separate address space (SMRAM) that has to be made inaccessible to other operating modes of the CPU by the firmware. [7] System Management Mode can address up to 4 GB memory as huge real mode. In x86-64 processors, SMM can address >4 GB memory as real address mode. [8]
A CPU shim. A CPU shim (also called CPU spacer) is a shim used between the CPU and the heat sink in a computer. Shims make it easier and less risky to mount a heatsink on the processor because it stabilizes the heatsink, preventing accidental damaging of the fragile CPU packaging. [1] They help distribute weight evenly over the surface.
