Tom's Hardware is supported by its audience. Heatsinks are devices used to keep computer processing units (CPUs) and chipsets cool. Hence, it allows high performance heat sinks to be fabricated for applications. Exactly where heat was sequestered in the oceans is not known with certainty, but there is broad agreement that the observed slowdown in surface temperature warming was the result of increased uptake of heat energy by the global ocean during those years. heatsink: A heatsink is a device that is attached to a microprocessor chip to keep it from overheating by absorbing its heat and dissipating it into the air. ‘Judging by the small size of the heat sink and fan on the processor, this is a fairly cool running processor.’ ‘If the mounting mechanism for those devices is not very sturdy, the heavy heat sink can still fall off because the mounting mechanism breaks off.’ ‘The clip on the heat sink is also a bit of a downfall.’ What is the meaning of a heatsink? If this heat is not kept in check, the processor could overheat and eventually destroy itself. This […] What should be noted is that the optimum heat sink design with 8 fins has a surface area 0.045 m 2 and the original design with 15 fins has a surface area of 0.084 m 2 and a thermal resistance that is significantly higher.
