If the system is having fewer intake fans and more exhaust fans, then the pressure inside the CPU is called Negative air pressure. Negative air pressure – (more ‘exhaust fans’) This leads to the generate more air pressure inside the case and eventually leads to the damage of hardware components or weakens the system performance. This is not the best air pressure inside the case because even if the input air or fresh air is high, the output air is low this means it does not exhaust the hot air from the computer components at the required level. In the CPU case in which more intake fans are present than the exhaust fans then the pressure inside the CPU is called positive air pressure. Positive air pressure – (more ‘intake fans’) No matter how many fans or slots you use, the pressure in a case must be any one of the above three types. We will see each of them and conclude which one is best to optimize PC airflow in a CPU case. Types of airflow in a CPU caseīased upon the pressure inside the CPU case, there are three types of air pressures. If I don’t do that, there is a chance of getting the Blue Screen error because of overheating. I noticed the fan is not working on my PC and I replaced it. I just want to show you the airflow direction. Of course, it is not working on my PC anymore. In the above picture, you can see the direction of airflow through the fan. PC Fan Airflow directionĪlways remember, the grill side is the way air out-coming through the fan. The fan airflow direction is the same for all computers. The intake of fresh air occurs through the front face of a fan, and the exhaust airflow goes out from the grill side. When the computer case fan spins, the airflow occurs through it. If you know this, it will be easy for you to set the optimized airflow in your CPU case without a doubt. Now you need to know the PC fan airflow direction. My suggestion is, choose a case that has at least 6 fan slots in it. It is all up to you to choose the best for you. Some cabinets support 140mm fans and some don’t. Not all manufacturers give the fan slots in the same way. But, you can choose CPU cabinets that feel good for you. The manufacturer makes the design of CPU fan slots in a cabinet. In some cabinets, you can see the side slot for a CPU fan. Well, the CPU fan is in all 4 directions (front, rear, top, and bottom) of a CPU cabinet. If you are building a PC, then these types of products (packs) are just fine for you to fit all the slots on your CPU cabinet.īuy CPU fan now Where is the CPU fan located? Make sure the quality and quantity as well before buying it. Sometimes, you may find a pack of 3 or 5 pieces in it. It costs more or less based on the features like RPM, speed control, RGB, etc. The price of a computer cooling fan is around $12 on average. When it comes to price a normal cooling fan is at a cheap price compared to the CPU cooler. If the fan has RGB lighting, it gives a colorful look to your computer.You can reduce the temperature effectively with the help of fans.( How much power does your computer consume?) There are the best advantages that you can get with a computer cooling fan Various fan sizes are available but 120mm is the most commonly used computer cooling fan. These fans are cheap in cost, effective in performance, and colorful to see. Useful reading: How many ways computers are useful to you? What is a computer cooling fan?Ī computer cooling fan is nothing but a small fan that can fit into a CPU case and help to increase the airflow in it.There is a way to cool down the temperature in a CPU case at a cheap cost – a CPU fan. So, mainly liquid cooling is used for the processor cooling instead of the entire CPU case. The liquid cooling technology is costly but shows a high impact on temperature control. If you are a gamer, never, ever compromise in controlling your CPU temperature. But now, liquid cooling is the latest technology that has a wide range of use. For example, all the processors you are using for domestic purposes are operating anywhere in between 55° – 80☌.īut the processors used in the military are more efficient and they even work in negative temperatures.īased on the processor architecture and its usage, various cooling techniques apply to it. However, based on the CPU architecture, the operating temperatures are different. But now, liquid cooling is dominating fan cooling. In the olden days, we had only CPU fans to control the CPU temperature. The process of controlling the temperature rise in a PC with the help of CPU coolers and fans is called a PC cooling system. How does the fan help in cooling the CPU?.Neutral air pressure – (intake fans = exhaust fans).Negative air pressure – (more ‘exhaust fans’). Positive air pressure – (more ‘intake fans’).
