Speaking of moving air, the stat you want to keep your eyes out for is “CFM,” which stands for “cubic feet per minute.” The higher the number, the more air the fan can move, the better. 120mm and 140mm also (normally) have the same mount size, and larger fans are generally quieter and move more air. Standard sizes range from 80mm to 250mm, and you’ll generally need larger fans for larger PC cases, since they’ll need to move more air. There are a few things you should look for when picking out PC fans.įirst, make sure you measure your PC case to make sure the fan you want will fit in the mounts your case has.
It’s also possible to install side-mounted fans, which should usually be in an intake position, but as a general rule of thumb, it’s best to have air flowing front to back. A rear exhaust helps to expel heat out of the case, while another exhaust fan at the top of the case, if it has ventilation and is away from intake fans, is useful for removing the rising hot air. A front intake fan ensures that fresh cool air flows over your PC’s components, and it can be helpful to have more than one if you’ve got the space. To prevent your hardware from throttling and overheating, a front intake fan and a rear exhaust fan are the most detrimental. £21.95 See on Amazon PC Fans FAQ Which fans are most important in a PC?
