A CPU cooler is a device that cools the CPU, generating proper airflow and preventing it from overheating. CPU coolers come in different types, with the most common being air and liquid coolers. Air coolers use their own fans to push air over the CPU, while liquid coolers use a liquid-filled radiator to dissipate heat.

When choosing a CPU cooler, it's important to consider the type, noise level, and cooling performance needed for the system. Air coolers are usually cheaper than liquid coolers but are often louder and less efficient at cooling.

Common PC Building Mistakes to Avoid

Whether you're a DIY enthusiast or a professional contractor, it's important to be aware of the most common mistakes people make when building.

Building your own computer can be exciting and rewarding, but it can also become upsetting and stressful if you have zero knowledge of what you're doing. Taking the time to read this PC building beginners guide can save you time, money, and a lot of stress in the long run.

1. Not Checking Compatibility

Incompatible components can result in issues of poor performance, system instability, and incompatibilities between components in your entire PC. These issues can be difficult and expensive to fix and may require replacing components.

Checking compatibility beforehand can help to ensure that all of your components are compatible and will work together properly. For instance, they might match their motherboard with the incorrect CPU or RAM. If a motherboard and CPU are not compatible, the system will not boot.

Additionally, if you have incompatible hardware, such as if a motherboard is not compatible with a certain type of RAM, the system may not be able to support the RAM, resulting in poor performance.

2. Forgetting the Motherboard I/O Shield Installation

Before installing the motherboard into the case, first-timers should ensure that their motherboard's I/O shield has been installed.

Forgetting to install the motherboard shield will have to take apart all the components to install it or risk unscrewing the motherboard and GPU while everything else is connected. To prevent all this extra work, make sure to install the I/O shield before securing the motherboard in the PC case.

3. Not Checking for Clearance

Though the motherboard and CPU are important parts of PC hardware, you should also pay attention to the sizes of other hardware components.

Checking for clearance is important when building a PC because it ensures that all components fit properly and do not interfere with each other. If clearance is not checked, components may not fit correctly and can cause damage to the components or the PC, as well as reduce the system's stability, performance, and longevity.

Cable management would also be tough if there were not enough room. You don't want your case to be smaller than your components and have them squished against each other.

4. Wrong Installation in the CPU socket

This error may be made by some first-time PC builders who are new to the PC building process. Avoiding too much force when installing your CPU is a common mistake. You must assess how much force to apply because you may risk breaking your CPU socket's pins.

Fortunately, determining where to install and how to place your CPU is very simple. The corners of every processor are marked to indicate which component goes exactly where on the motherboard to avoid locking it in the wrong way. Once you've located the marking, carefully install the processor by aligning it with the marking on the motherboard's CPU socket.

5. Forgetting to Plug-in All the Cables

Forgetting to plug in the cables can cause several problems with a PC build. If the cables are not connected properly, the PC components may not receive the necessary power, leading to poor performance, unexpected shutdowns, and even damage to the components. Additionally, all cables not plugged-in can create a potential hazard for users and cause the PC to be unstable.

6. Not Paying Attention to Cooling

Without proper cooling, all components will run hotter, leading to decreased performance and even hardware damage due to overheating. Additionally, the PC will be louder due to the additional cooling fans running. You can ensure that your PC runs smoothly and quietly by ensuring your PC receives enough cooling.

7. Not Using the Right Thermal Paste

If you are a first-time pc builder, you may wonder how important thermal paste is in your own PC. Thermal paste is an essential component for PC building. It could get pretty messy if you don't take care when installing your thermal paste.

Installation of thermal paste is creative. If you apply liquid metal, too much of it may seep out and damage the surface. Your PC build will overheat if there is an insufficient thermal paste, and you might not even be aware of it.

When putting the thermal paste, it is recommended that you put a drop of thermal paste about the size of a rice grain in the center of the back of your CPU, where it should spread out nicely and evenly in a thin layer.

8. Buying a Low-Quality PSU

One of the common PC building mistakes is buying a low-quality power supply. When it comes to power supplies, there is a difference between spending less money on a low-quality model and a cheap power supply. It's acceptable to spend on an affordable power supply if you have a tight budget and your PC's other components don't require a lot of power.

Not all power supplies are created equal. Buying a low-quality PSU can be prone to failure, leading to expensive repair bills, the risk of damaging components in the system due to static electricity, or even a complete system failure. Low-quality PSUs may also produce more electrical noise than high-quality ones, leading to reduced system stability and performance.
