Cpu Heatsink Fan Direction

The intake exhaust direction should go front to back and bottom to top.

Cpu heatsink fan direction.

Yes but it s 99 likely that you don t actually want to do that. This is where the exhaust fan s will take over dragging this warmer air out of the case. Please describe your reasoning for changing the airflow direction. However as i also stated ymmv so try it both ways.

You can make sure that the system isn t too loud with the fan only spinning up faster when your pc gets warm. There are several options for how a cpu cooler can exhaust heat from the cpu. Rear exhaust fax heatsink cpu fan. Exhaust fans go on the rear or the top.

Do not mount exhaust fans on the bottom of the case. Airflow through the case is important so yes it matters. Most cpu cooler. Depending on the heatsink designs the fan needs to blow suck in a given direction.

Arguably the heat sink shown above might be more efficient with longer fins and the fan mounted at one end. In those circumstances installing the fan in the suck direction can actually improve the situation since the air will enter the sides of the heat sink more linearly to fill the void in air pressure created by the fan. The airflow through the fins of the. Don t say you re doing it to make it quieter.

You ll actually make it louder. Not all heatsinks need the fan to suck air away. 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. When the fan blows on the heat.

Suggested fan placement and cooling cpu heatsink fan blowing down on heatsink fan in front of case pulling in cool air fan in rear of case pulling hot air out of the case and blowing out the back fan on top pulling warm air out of the case heat rises most instances side case fans pulling cool air into the case with the exception of any very near the top of the case to take. The heat sink draws heat away from the cpu and the fan sucks the heat away from the heat sink to cool it it shouldn. It is common sense that a cpu cooler with tower heatsink must be installed with its fan pulling air from the front of the case blowing in direction of the rear of the case.
