Cpu Heatsink Fan Direction

Since hot air rises a bottom firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air.

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. There are several options for how a cpu cooler can exhaust heat from the cpu. Most cpu cooler. Rear exhaust fax heatsink cpu fan.

Exhaust fans go on the rear or the top. 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. 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. Depending on the heatsink designs the fan needs to blow suck in a given direction.

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. Please describe your reasoning for changing the airflow direction. When the fan blows on the heat. Don t say you re doing it to make it quieter.

The airflow through the fins of the. Do not mount exhaust fans on the bottom 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. 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.

This is the intel factory cooler for a socket 1150 system note it s not much different than several other. Airflow through the case is important so yes it matters. Yes but it s 99 likely that you don t actually want to do that. You ll actually make it louder.

However as i also stated ymmv so try it both ways. Not all heatsinks need the fan to suck air away. The intake exhaust direction should go front to back and bottom to top.
