How to Buy a Case Fan
The action of a computer is entirely similar to human behavior. Every human has a limit just like a computer. If you work 24 hours a day with no food or water, you will perform below standard because your body system will break down completely. A computer with an overheating CPU will perform poorly or possibly crash, and this may ruin your day. When you set out to buy a case fan that suits your gaming PC, there are some important features you need to consider. Below are a few things to consider.
Size:
There different sizes ranging from 25mm – 250mm, but the common sizes are 80mm, 120mm and 140mm. You need to choose the size that works best for your gaming PC. If possible, choose a 140mm for a gaming PC because they provide your PC with the best active cooling system at lower RPMs.
Noise:
Noisy fans can drive you insane. Your best option is to choose a case fan with less noise. If you are a blogger, then you want to choose a case fan with little or no noise.
Airflow:
Airflow is the major reason you are buying a case fan. To ensure your PC receives the right airflow, you should buy a case fan with the maximum airflow.
Power Connector:
Case fans are connected to the motherboard of your PC. Your motherboard usually has 2 pins; the 4 pins connector fans have PWN function to keep the speed in check. The 3 pin fans come with tachometer functions that allow the fans RPM to read your PC’s motherboard.
