![]() The important feature of larger fans is that they can move the same CFM of air as a smaller fan, but at less RPM than the smaller fan. The higher the CFM, the more cooling power a fan has.įan Size: you may think that a larger fan is a more powerful fan, but this is not necessarily true. Obviously, the higher the RPM spec a fan has, the faster it can spin.ĬFM: This stands for cubic feet per minute, and indicates the volume of air a fan can move each minute. RPM: This stands for revolutions per minute, and is a measure of how many times per minute the fan blade makes one complete rotation. If you’re interested in other cooling systems and wonder if they’re worth it, also check out this guide. ![]() Now that we have some guidelines for the placement and direction of fans, let’s talk about some of the key parameters that define fan performance. You can improve airflow by adding an intake fan to either this side vent or to the front of the case, provided there is a fan mount point there.įinally, if your case has a fan mount point on the top, this should be for exhaust, since warm air rises. Many computer cases contain only these two fans and rely on cool air naturally entering through a side vent as the intake. Take a look at this guide if you’re wondering how hot your CPU can safely run. Just about every computer case has a fan in the back panel this should be an exhaust fan.Īdditionally, the fan mounted to your CPU should be configured as an exhaust fan so that it directs the hot air generated by your CPU away from it. Next, we’ll talk about general recommendations for fan location and airflow direction. If the fan has a protective grill, it will be on the side of the fan where air exits.If present, this arrow indicates the direction of airflow through the fan. If you feel air blowing on your hand, the fan is an exhaust. There are a few ways you can determine the airflow direction of any fan: If you are having a mini tower or slim tower cabinet then I advise you get a full tower or mid-tower cabinet for your PC because mini and slim tower cabinets do not have enough room inside them which results in very poor air flow.7 Final Recommendations How to Determine Fan Airflow DirectionĪ computer case fan can either be an intake, meaning it sucks air into the case, or an exhaust, meaning it blows air out of the case. Know About Various Tools to Keep your PC Clean Use Full / Mid Tower Cabinet You can clean the outside or outer surface of the cabinet with the help of a damp cloth but for inside you have to use an air blower which you can find in any hardware shop. Keep the cabinet clean from inside as well as from outside. ![]() Keep the covers off when you are using the PC. Don’t cover it when usingĭo not cover your PC when it is turned on. This is known as cable management and it plays an important role in achieving good airflow. You can use plastic wires or cables to tie the cables. Tie up your cables which are going to the same place so that they do not block the flow of air. Note: Make sure you have a good SMPS of sufficient Wattage installed in your cabinet as fans consumes decent amount of current which put load on your PSU.
