Processor Cooling Methods for Desktop, Laptop and Server are same at some points and are quite different too. Let us have a look at Processor Cooling Methods. Data Center Cooling is a separate but related topic on which we wrote articles before.
Why Processor Cooling is required
Intel 486 processor has need cooling. The processors at that time were never went hot while running. The surrounding air inside the computer case was enough to cool it. With exceeding frequency, at least a passive cooling with a heat sink become a standard required. At much higher clock frequencies, a processor can only be operated with an active cooler. Otherwise it will burn in to ashes or the BIOS will shutdown or Hibernate the computer.
Fundamentals of Processor Cooling
The heat dissipation for Processor Cooling is usually achieved by using air or water in combination with a heat sink, which is firmly connected to the surface. Unfortunately, the heat sink only a limited thermal conductivity and lower heat dissipation index. Therefore, heat is removed by air flow or water flow heating for Processor Cooling . By a higher air flow Processor Cooling can be achieved, a higher air flow is generated by rapidly rotating fan, which also adds higher noise levels along with Processor Cooling.
Processor Cooling methods
There are several measures for Processor Cooling. One measure for Processor Cooling is passive Processor Cooling, which used in almost all laptops while running on battery, a heat sink extends to the case by a heat-dissipating component.
With active Processor Cooling cooling method, a heat sink fan, which ensures that the heated heat sink cools faster is added. Active Processor Cooling cooling has the disadvantage that it requires additional space and power.
Factors controlling Processor Cooling
There are several measures for Processor Cooling. One measure is purely passive uses in almost all semiconductors. For example, a transistor or a voltage regulator with a heat sink extends to the case by a heat-dissipating component.
With active cooling a fan is applied in addition to the heat sink fan, which ensures that the heated heat sink cools faster. Active cooling has the disadvantage that it requires additional space and power.
