You can put the fan anywhere that it fits. You can never add too many. I have two added fans in mine. I put one in the front and one on the back (inside) where there are vent holes. Have the fans blowing in the same direction, towards the rear. Make sure the fans don't rub on any boards. Your computer has one fan in the power supply and/or a small one on the cpu. You may not need more than that.
The installation of a CPU fan horizontally to the plane of the motherboard is the most common installation orientation there is. Your options when installing your CPU fan are to blow cool air onto the heat sink or to pull cool air through the heat sink from the motherboard. Horizontal installations show negligible advantages in either installation direction. The differences in temperature usually vary by only 1 or 2 degrees Celsius. The main point to consider when installing a horizontal CPU fan is the location of the rear exhaust fan on the case. If the rear exhaust fan on the case is parallel to the processor, it is advantageous to have the fan pull cool air from the motherboard and push it out above the heat sink. This is because the case fan will quickly draw that hot air away from the CPU and out of the case, allowing for quick cooling.
Vertical, or tower, heat sinks rise high enough off the motherboard to allow for a fan to be installed perpendicular to the plane of the motherboard. This allows for cooling to go from the front to the back of the case, as opposed to going from the bottom to the top. Optimal installations for vertical heat sinks are blowing toward either the back or the top of the case. If there is no exhaust fan in the top face of your computer's case, it is more effective to orient your fan on your vertical heat sink so that it blows toward the rear exhaust fan of the case. If there is an exhaust fan on the top face of your computer case, it is almost always more effective to mount your CPU fan so that it blows air up toward the top of your case. The reasoning behind this is that hot air rises and will more naturally flow off the top of your case. Also, top-mounted fans are usually larger and allow for faster airflow out of the case.
It is often the case with nonstock heat sinks that the manufacturer has designed the heat sink's fan to be mounted in a limited number of orientations. This is usually evidenced by limited mounting notches on the heat sink itself. Most aftermarket heat sinks use technologies such as heat pipes that have specific cooling needs to operate appropriately. Because of this, it is important that in any CPU fan installation you follow the manufacturer's installation instructions.
You will notice that replacing the fan is not specifically
mentioned, but it should be fairly easy.
Open the case as noted in the instructions, follow the power
wire from the fan to the motherboard, then unplug the connector from the
motherboard, and remove the assembly.
Some of the earlier fan shrouds just lift up and out, but
others have tabs to hold them in.
Regarding the fan, there might be two release levers
accessible from inside the case, but the one by the PSU can be hard to
reach.
It might easier to push the retaining tabs, in from outside,
using a small screwdriver, pen or whatever.
The installation of the new fan, is just a matter of fixing
the new one in place and connecting the cable.
Good luck, and do rate the solution if got help

i do not understand how to remove the cooling fan from the CPU on a PC. It is very noisy and I want to replace it with a new one. How do I remove the fan?
