How important case fan is for average use and continous running ?

 

how many case fan needs at least ?

Depends on your build. Totally silent systems can run without fans but if you have a GPU you should have at least one fan.

My account is almost entirely dormant. Hope you all are having a grand time. Many years of fun were had here.

Well you need at least one case fan for a normal PC, and it is ideal to have at least two if you have a dGPU.

 Processor and power supply have fans.

Should i need additional case fans ?

Do fan increase component life span ?

More fans improve airflow and temps. At the minimum you should have at least 1 intake fan and 1 exhaust fan.

Processors can run on passive coolers and not all PSUs have fans.

You should use at least one case fan as an exhaust out the back of your case and use more if temps look too high. It can increase the lifespan of your components because they can stay cooler.

Fans move the air in and out. Without them the air inside case gets and remains hot. With light loads, that doesn't have much effect. But with higher loads where all parts heat already, having high temp inside case makes things worse.

 

Ideal setup for fans is 2-1, 2 intakes (front) and single exhaust (rear).
