What should the direction of the CPU fan face?

If in doubt about the direction of air flow through your CPU fan, apart from the labels and markings it may have, you should be able to figure out from the direction of rotation which way the air is going. You want the coldest air possible being pushed or pulled through the heat exchanger for optimal convection-cooling.

Do you need to cool your computer with a fan?

If there is one component in your PC that needs to be kept cool, it’s the CPU. Not only will overheating degrade performance, but it can permanently damage your computer. That’s why you need to install an appropriate CPU cooler, which consists of a CPU heatsink and CPU fan.

Which is the best fan layout for CPU cooling?

Switch either direction of CPU cooler to exhaust top and make all top exhausts (rear can be intake, but you need filter for it). Or remove 1-2 top fans and leave rest as exhausts. Neither of those can really do much for temps.

When does a CPU fan need to blow air away?

The only time a CPU fan should blow air AWAY from a CPU is if you have another fan blowing air IN to the CPU (i.e., dual fan setup or a large case fan on the other side blowing air to it).
