If you are building a computer, one important thing that you should pay close attention to is cooling. Case fans<\/strong> create an airflow inside your case that takes in cool air and exhausts hot air. And all those fans plug into the motherboard<\/a><\/strong>. So, how to tell how many fan headers a motherboard has?<\/strong><\/p>\n\n\n\n The easiest and best way to check how many fan headers some motherboard has is to go to the manufacturer’s website. You can type in the exact model of the motherboard you are interested in. Once you find it, find the specifications list. Look for “CPU fan header<\/em>” and “system fan header<\/em>“. That is how to tell how many fan headers a motherboard has.<\/strong><\/p>\n\n\n\n But if you already have the motherboard, you can check it yourself as well. You can find out more about this topic down below.<\/p>\n\n\n\n Basically, all motherboards have at least one CPU fan header<\/strong> and one system fan header<\/strong>. That is because your CPU needs a dedicated cooler due to the massive heat generated by it. The CPU cooler consists of a heatsink that takes the heat away from the CPU and a fan that cools the heatsink itself.<\/p>\n\n\n\n And the rest of your computer has to exhaust the excess heat generated by your CPU, GPU, and other components somewhere. That’s where the system fan comes in. It is usually mounted in the back and the fan header for it is fairly easy to spot too.<\/p>\n\n\n\n It is important to make a distinction between 3-pin<\/strong> and 4-pin fan headers<\/strong>. 3-pin<\/strong> and 4-pin fans<\/strong> are compatible with both 3-pin and 4-pin headers. The only difference is that the fourth pin on a 4-pin header serves for fan speed. Without it, the fan always runs at 100%.<\/p>\n\n\n\n You will typically see a 4-pin fan header next to your CPU and 3-pin fan headers everywhere else. Bear in mind that there are many different layouts and designs in the world of motherboards, so you may see multiple 4-pin fan headers on the motherboard.<\/p>\n\n\n\nHow to Tell How Many Fan Headers a Motherboard Has?<\/h2>\n\n\n\n
