Mainboard of a NeXTcube computer (1990) with 32 bit microprocessor Motorola 68040 operated at 25 MHz. At the lower edge of the image and left from the middle, the heat sink mounted directly on the CPU can be seen. There was no dedicated fan for the CPU. The only other IC with a heat sink is the RAMDAC (right from CPU).
A 'Northwood' core Pentium 4 processor. At left is the die (black square in the center), and at right the heat spreader. Die shot of a Northwood Pentium 4. In January 2002, Intel released Pentium 4s with a new core codenamed Northwood at speeds of 1.6 GHz, 1.8 GHz, 2 GHz and 2.2 GHz.
To reduce weight and cost, many laptop computers choose to use a much lighter, lower-cost cooling system designed around a much lower Thermal Design Power, that is somewhat above expected maximum frequency, typical workload, and typical environment. Typically such systems reduce (throttle) the clock rate when the CPU die temperature gets too ...
Heatsink mounted on a motherboard, cooling the CPU underneath it. This heatsink is designed with the cooling capacity matching the CPU’s TDP. 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 ...
Thermal resistance is defined as temperature rise per unit of power, analogous to electrical resistance, and is expressed in units of degrees Celsius per watt (°C/W). If the device dissipation in watts is known, and the total thermal resistance is calculated, the temperature rise of the die over the ambient air can be calculated.
Every degree set higher than the recommended range can save you about 5% on cooling costs. Customers can also request a meter check and obtain a new “smart meter” if one is not already in place.
