Placing a conductive thick metal plate, referred to as a cold plate, as a heat transfer interface between a heat source and a cold flowing fluid (or any other heat sink) may improve the cooling performance. In such arrangement, the heat source is cooled under the thick plate instead of being cooled in direct contact with the cooling fluid.
When the CPU uses power management features to reduce energy use, other components, such as the motherboard and chipset, take up a larger proportion of the computer's energy. In applications where the computer is often heavily loaded, such as scientific computing, performance per watt (how much computing the CPU does per unit of energy) becomes ...
Although the pin-fin has 194 cm 2 surface area while the straight-fin has 58 cm 2, the temperature difference between the heat-sink base and the ambient air for the pin fin is 50 °C, but for the straight-fin it was 44 °C, or 6 °C better than the pin fin. Pin fin heat sink performance is significantly better than straight fins when used in ...
To better understand the problem we must remember the basic concepts underlying Thermal management and Computer cooling. [26] Let’s consider the thermal conduction path from the CPU case to the ambient air through a Heat sink, with: Pd = Thermal power generated by a CPU and to be dissipated into the ambient through a suitable Heat sink.

The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the activity factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
To be fair, that’s addressed in the number 1 tip from Yeti to help keep your cooler colder, longer: “Preload your cooler a few hours prior to use with a sacrificial bag of ice to cool it down.”
A Cooler Master computer heat sink has many heat pipes. CPU cooler Thermalright Le Grand Macho RT installed into the computer case. Air cooling is a method of dissipating heat. It works by expanding the surface area or increasing the flow of air over the object to be cooled, or both.
