Cpu Heatsink Fan Direction

Arguably the heat sink shown above might be more efficient with longer fins and the fan mounted at one end.

Cpu heatsink fan direction.

Rear exhaust fax heatsink cpu fan. Most cpu cooler. Airflow through the case is important so yes it matters. You ll actually make it louder.

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. The intake exhaust direction should go front to back and bottom to top. There are several options for how a cpu cooler can exhaust heat from the cpu. Please describe your reasoning for changing the airflow direction.

Since hot air rises a bottom firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air. You can make sure that the system isn t too loud with the fan only spinning up faster when your pc gets warm. 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. Do not mount exhaust fans on the bottom of the case.

This is where the exhaust fan s will take over dragging this warmer air out of the case. Not all heatsinks need the fan to suck air away. Exhaust fans go on the rear or the top. This is the intel factory cooler for a socket 1150 system note it s not much different than several other.

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. When the fan blows on the heat. 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. However as i also stated ymmv so try it both ways.

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. Don t say you re doing it to make it quieter. Yes but it s 99 likely that you don t actually want to do that.
