Airflow or static pressure.
Pc case fan static pressure.
Best 120mm 140mm static pressure fans for radiators heatsinks and restricted spaces in pc case.
Corsair for example sells quiet edition high static pressure fans.
Set on low these fans runs at 1 450 rpm and push 37 85 cfm while producing just 23 dba.
Unlike most pc components fans are mechanical systems.
Radiators and case meshes are becoming more common in pc builds which is where static pressure fans have been marketed towards.
If there is anything impeding your airflow such as blocking the air from going through the vent from behind a static pressure fan will be far more efficient.
Cooler master masterfan mf120 halo duo ring addressable rgb lighting 120mm 3 pack w 24 independently controlled leds absorbing rubber pads pwm static pressure for computer case liquid radiator type.
Also there is a lesser gap between the adjacent.
The fan blades of high static pressure fans are more curved and are directed towards the heat source.
Some fans and cases even come with manual switches for basic fan control.
Now that the impromptu physics class is over and done with let us get back to the issue at hand.
By igor wallossek 16 november 2011 after discussing the theory of pc cooling in part one we now move on to technology and implementation discussing case fans cpu coolers and thermal grease.
Static pressure fans are great for radiators and case meshes and use resistance to push heat through your pc build.
Case fans generally come with two types of fins.
High airflow fans can run into problems when installed in a case with restricted airflow that s what high static pressure fans are for.
Airflow optimized fans are quieter and great for unrestricted areas like the front of your case.
Cooling fans on a pc case can be installed either as an intake bringing air into the case or as an exhaust moving air out of the case.
