It's quite literally a combined heat sink and fan. It's used to help keep a CPU -- Central Processing Unit -- from over heating.
The combination heat sink and cooling fan is sometimes called a cooler.
Cooling fan is always better. By:B.J
The difference is that Passive cooling is just a heat sink that dissipates the heat into the air without the help of a fan. Active cooling is when you have a heat sink and a fan is directly blowing/sucking air thru the heat sink to cool it. The fan does not have to be on the heat sink as with some dell/gateway computers. The fan is on the plastic shroud, which in turn fits right over the heat sink. Water cooling and phase-change cooling is also considered active cooling.
A Fan sink is a Heat sink with a fixed FAN. Heat sink's are blocks of metal, primarily used are are copper, and aluminum, that draw heat from a source ( such as your Processor, or another heat producing chip set ) and spread it across its surface area to be air cooled. A Fan sink, combine's the heat drawing of it's sink with a dedicated fan blowing air into ore out from the heat sink below it. This will significantly improve the sinks cooling power. So a processor cooler is most likely a Fan sink, but some chips surrounding it may only have a heat sink. ( Southbridge controller is usually placed near your CPU and is fitted with a black block of metal that has a lot of blades on it )
A heat-sink fan is a cooling device commonly used in electronics, particularly in computers, to dissipate heat generated by components like CPUs and GPUs. It consists of a heat sink, typically made of metal, which absorbs heat from the component, and a fan that enhances airflow over the heat sink, facilitating heat transfer to the surrounding air. This helps maintain optimal operating temperatures, preventing overheating and ensuring reliable performance. Heat-sink fans are essential for maintaining thermal management in high-performance computing systems.
Yes, active heat sinks use a fan or other mechanism to enhance heat dissipation beyond what a passive heat sink can achieve. When replacing a passive heat sink with an active one, ensure compatibility with your hardware, consider power requirements for the fan, and account for any additional noise generated by the active cooling system.
Most computer processors liberate heat by mounting a metallic heat sink and fan on the processor itself. Gamers' systems may however feature liquid cooling.
The heat sink and fan are typically located on the CPU or GPU of a computer. The heat sink is usually mounted directly on top of the processor, while the fan is positioned adjacent to it to facilitate airflow and dissipate heat. In laptops, this assembly is often found on the underside or side of the device, while in desktop computers, it is usually located inside the case, near the motherboard. Proper placement ensures effective cooling to maintain optimal operating temperatures.
With a heat sink and fan.
In a active heatsink system you have both a heatsink and a fan thus for the most part an active heatsink cools better with one exception. Should the fan fail the active heatsink will quickly overheat. Passive heatsinks relay on transferring heat without the aid of a fan. The advantage here is that a passive heatsink is fail proof and uses 0 electricity, however passive heatsinks don't typical cool as well. Passive heatsinks work great for supporting chips and RAM cooling. They are also found in servers because of the no fail aspect. EnzoTech produces some passive heatsinks you can read a bit more about them here: http://electricalninja.com/
They're used to help keep the processor on the motherboard inside the Central Processing Unit (CPU) from overheating. Both are necessary: the fan actually protects all the devices inside the CPU from overheating, while the heat sink is used especially for the processor as it gets overheated quickly.
