Case Fans

[acemasta]

how many fans are considered a good amount of fans for a new mid tower case. it might go through some mild overclocking

[Alaron]

There are too many variables to really answer that. The components being used, the quality of the wiring job, ambient room temps, case design, etc.

But as a rule of thumb, I'd start with one exhaust in the back of the case and one intake in the front. You really shouldn't need more then that, but I would start low and add if needed, rather then buying a bunch that aren't needed.

For a non-overclocked computer...1 exhaust fan in the back is enough.

For a computer that runs on the hot side...1 exhaust fan in the back and a intake fan up front.

For a over-clocked computer...2 exhaust fans in back (if possible, if not 1 120mm), 2 up front for intake, 1 or 2 side fans blowing into the case and 1 exhaust fan up top blowing air up out of the case.

Honestly though...adjust the number of fans after you start over-clocking and then you'll know just how much hotter your computer runs. Then you figure out how much more cooling you need.

Keep in mind too many fans will ruin airflow. You want to have some type of airflow (ie, fresh air coming in the front, flowing over components and out the rear) going on. Too many fans and you'll end up with lots of turbulence and no real air being moved. Another good reason to start out with just 1 or 2 and see how things go.

hmmm ok ... does it matter if the fan is 80mm or 120mm?

[JonDee]

It might make a difference in the sound level. The 120mm fans are usually quieter.

Also, you case might only support certain ones.

hmmm ok ... does it matter if the fan is 80mm or 120mm?120mm fans can move more air while spinning at a lower RPM to help keep noise levels down. Some cases also accept 92mm fans...a nice compromise between 80mm and 120mm fans.

80mm is the standard case fan size but more cases are now coming out with 92mm and 120mm fan ports.
