Question about Video Game Consoles & Games
The installation and use of cooling fans in PCs is pretty
straightforward once you understand the airflow layout and mechanical assembly.
You need to learn the necessary skills to make sure you are setting up your fans to direct the air where it will do the most good, as well as how to choose (and mount) the correct fan(s) for your situation.
Computer fans are manufactured in five distinct varieties: case fans, expansion-slot fans, hard-drive coolers, CPU fans and external drive-bay fans.
With case fans, there are several physical sizes that are measured in millimeters.
Another measurement the manufacturer will provide is the CFM (Cubic Feet per Minute) the fan is rated for.
As a general rule, the smaller the fan in size and the higher the CFM rating, the more noise it will create.
Before you purchase additional fans, open your case to see what kind of fans can be added.
The fan size must match the size of the opening in the case to be at peak efficiency.
You will need to establish you have expansion slots available if you want to add an expansion slot-style fan.
It is crucial you establish a pathway for the air being moved inside your case to follow.
As an example, having all the fans blowing air from the outside of the case to the inside is not as efficient as having fans on the front of the case blowing cool air in while the fans located in the back of the case are sucking out hot air.
It is recommended the best practice is to position a case fan in the front bottom of your case (bringing in cold air) and at least one fan mounted midway up the rear of your case (expelling hot air).
If possible, use two fans in the back to expel the hot air as a lot of it is being introduced by the CPU cooling fan.
The mounting of case fans is done by using four course-thread screws usually provided with the fan.
These screws are self-tapping and will be inserted through the hole in the case wall created for a case-fan screw, then screwed into the case-fan body mounting hole.
Make sure you use all four screws to hold the fan securely.
The installation of an expansion slot fan can target specific areas where heat is generated.
When mounting one of these fans, make sure the expansion slot fan is not in direct competition with the fan mounted to a video card.
Having the expansion slot fan blowing directly into the video card's fan, which is trying to blow out air, will defeat both of the fans' purpose.
Hard-drive coolers usually mount to the circuit board side of the hard drive and work to keep it cool.
Because of the location of most hard drives, there is very little disturbance from the air that is released from the hard-drive cooler to the airflow pattern mentioned earlier.
External drive bay fans can provide an enormous amount if airflow, assuming there is an external drive bay open.
