Ideally you want to place an exhaust fan as close to the cpu as possible to quickly expel this hot air.
Processor heatsink fan direction.
A side mounted fan expelling or drawing in air in a direction perpendicular to the motherboard might be useful here but not all cases support that.
No not all heatsinks need.
In the screenshot below it was listed as pc health status.
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.
When possible direct cpu cooler output to the nearest exhaust fan.
The first is an air cooler which comes with a big metal heat sink and a fan that pulls air away heat from the cpu.
Every bios is different so instructions may differ from computer to computer but you need to look for a tab or screen to do with hardware monitoring.
Control cpu fan in the bios the easiest way to adjust cpu fan speed is through the bios.
This is where the exhaust fan s will take over dragging this warmer air out of the case.
The rear or exhaust side the side that the air comes out of of our fans will always be the side that houses the fan motor.
Cpu coolers generally come in two varieties.
When a single source of airflow is divided the volume remains the same but the airspeed through each individual pathway is reduced.
Cpu heat sink fans are usually low volume suppliers of air.
When looking at our fans the front or intake side of the fan will always be the side that has the cooler master logo in the center of the blades.
