In the video above, the YouTuber stress tested a computer with no fans other than those on the CPU and GPU. Server chassis cooling designĮven if all of the cooling mechanisms are in the right places inside of your server, there needs to be air running through it. Heat sinks are also used for chipsets and VRMs on a motherboard. GPUs and CPUs will have an IHS, heatsink and fan while chips on the motherboard and RAM will only have an IHS. In summary, your server manages heat for different components in different ways. On top of that, the fan needs to have access to airflow. Servers on the other hand will need a fan in addition to the heat sink. This is essentially a bigger chunk of metal that spreads out heat to a greater extent.įor low powered chips, like in a Macbook Air, the heat sink is enough for cool the CPU while browsing the web. All non-mobile CPUs and GPUs will have some kind of heat sink attached to them. The more powerful a chip, the less an IHS will be able to manage heat. Internal Heat Spreaders ( IHS) are the first lev el of heat dissipation. Because of this (and unrelated reasons) silicon itself is never exposed and is always covered by a heat spreader. ![]() Silicon chips in processors, motherboards, and almost every other computer component generate heat at a rapid rate when under load. Because of this, knowing as much as you can about airflow is essential to managing a server rack.Įven up to the data center level air flow works the same, albeit, managed with different mechanisms. Computing equipment is notorious for generating heat and servers can pack some very powerful equipment.
