You should only ever plug in any fans related to your CPU’s cooling into CPU_FAN first and then CPU_OPT optionally. This is especially true for the CPU_FAN and CPU_OPT headers. So even though you can plug any 3 or 4-pin connector into any 3 or 4-pin header, it’s best to plug the fans into the designated fan headers and anything else that you need into their own headers like “PUMP_FAN1″- if they have their own headers, not all motherboards have specific headers like that. The reason they’re labeled differently is that certain fans and cooling-related components have different requirements.įor example, a system fan doesn’t need all that much power to run, so it doesn’t have as much amperage or Wattage compared to the CPU fan header or pump fan header. Your motherboard will most likely have at the very least two or three headers like this.Īny one of those can and will power a fan just fine.Ī Fan Header’s Label on your Motherboard will generally end with “_FAN”, followed by a number. In short, the place you connect any standard consumer fan to is one of the many 3 or 4-pin fan header(s) on your motherboard. Let’s see: Where to Connect All Your Fans With so many different possible places you could connect your fan to, where exactly are you supposed to plug in all your fans to make sure your computer doesn’t overheat? You can’t have too many, you can’t have too little.įor being something that does the relatively simple task of moving air from one place to the next, it sure has some complicated quirks.Īnd one of the other “quirks” of fans is figuring out where to plug them in to- on your Motherboard or otherwise.
