Cpu Heatsink Fan Direction

Controlling the cpu fan speed in your pc or all the fans in fact is a way to give you more control over your windows 10 experience.

Cpu heatsink fan direction. Airflow through the case is important so yes it matters. Arguably the heat sink shown above might be more efficient with longer fins and the fan mounted at one end. However as i also stated ymmv so try it both ways. This is where the exhaust fan s will take over dragging this warmer air out of the case.

There are several options for how a cpu cooler can exhaust heat from the cpu. Yes but it s 99 likely that you don t actually want to do that. You ll actually make it louder. Most cpu cooler.

The airflow through the fins of the. Rear exhaust fax heatsink cpu fan. The intake exhaust direction should go front to back and bottom to top. Since hot air rises a bottom firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air.

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. 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. Please describe your reasoning for changing the airflow direction. 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.

Depending on the heatsink designs the fan needs to blow suck in a given direction. When the fan blows on the heat. Do not mount exhaust fans on the bottom of the case. You can make sure that the system isn t too loud with the fan only spinning up faster when your pc gets warm.

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. Not all heatsinks need the fan to suck air away. Exhaust fans go on the rear or the top.
