Cpu fan how does it work

You do not need to install drivers for a case fan to function. Some CPU fans attach directly to the heat sink , and the heat sink is then attached to the motherboard. Other CPU fans come with a built-in heat sink, and the whole unit connects to the motherboard. Refer to the instructions that came with the CPU fan for the proper installation steps.

Make sure to follow the installation steps very closely and carefully to ensure the CPU fan is installed correctly and facing the right direction for proper airflow.

You do not need to install drivers for a CPU fan to function. A power supply comes with a fan built into the unit, so there is no need to install a fan inside a power supply.

If the fan in the power supply unit stops working, you can try cleaning it out using compressed air to see if that resolves the issue. Otherwise, you need to replace the entire power supply unit. Higher-end video cards come with a built-in fan, so there is no need to install a fan on or inside the video card.

I was skeptical of the manufacturers statement that it was zinc covered copper. So I went and got a heatsink and with my boss's permission started to use a filing tool to file off the metal to prove if that was an accurate statement. After removing the coating of zinc, I discovered that indeed, the base and heatpipes were made of copper. Not only were my fears resolved, but Noctua was proven by fire once again to have a solid product. But I was able to have fun with it! Here are some pictures to prove I can break things too!

Here you can see the heatsink which has a copper heatpipe, and the copper base which were exposed after filing off the zinc coating. Zinc does not have as good of thermal conductivity as copper or aluminum, but being as it is such a small amount of it a very thin layer like paint It does not really affect the cooling ability of the unit. It was likely done as Zinc is resistant to corrosion and copper as we know can corrode. After reading this, you probably think I like to break some of our new products, but that is not the case at all.

And to make you feel better about me breaking perfectly nice things, after I was done attacking this cooler, I sanded down and cleaned the unit and we will actually use it internally for a specific use. After reading this article, I hope you have a better understanding of how CPU coolers work and also learned a little bit about how we test new products.

Also Read: The Best CPU Coolers A liquid cooling system essentially applies the same idea but replaces the copper heatpipes with tubes filled with a thermally conductive liquid that is pumped to a radiator. Processors that are sold with a heat sink and CPU fan normally carry a 5-year warranty, while those sold without commonly but not always carry a warranty of one year.

While the processors might be identical, manufacturers know that inadequate cooling can drastically shorten the life of a CPU. In the case of a CPU sold without a heat sink and fan, the manufacturer has no guarantee that a customer will provide proper cooling. Overclockers are computer enthusiasts that push CPUs, making them work faster than their marketed specifications. He began his writing career in and now works full-time as a writer and transcriptionist. His primary fields of expertise include computers, astronomy, alternative energy sources and the environment.

By Milton Kazmeyer. Convection The basic thermodynamic principle behind CPU cooling is convection. Heat Sinks Simply passing air over a CPU will not be sufficient to cool it, due to the high temperatures these chips can reach. Cooling Efficiency You can keep your CPU cooling fan working at maximum efficiency by following a few steps.
