While many modern games come with built-in benchmarks to help you instantly assess whether your system runs the game smoothly or if settings are too high or too low, not everyone buys a PC just for gaming. For productivity or professional use, third-party benchmarking tools are a better way to measure your system's performance through detailed data.

Developed by Maxon, Cinebench R23 is a free CPU benchmarking tool that evaluates both single-core and multi-core performance using the Cinema 4D rendering engine to simulate real 3D scene rendering. It’s one of the most widely used benchmarking standards in the industry and among DIY enthusiasts. Bonus: It also supports macOS!

Created by CPUID, CPU-Z is a popular tool for viewing detailed hardware information. It also includes a built-in benchmark module that tests both single-core and multi-core performance using compute-heavy tasks. Unlike Cinebench, it doesn’t simulate real-world scenarios but provides quick and simple performance data.

3DMark is a professional-grade benchmarking tool for testing GPU and overall system performance. It can simulate gaming scenarios, heavy graphics rendering, ray tracing, and more—providing a performance score based on your hardware.In addition to GPU tests (like ray tracing and DirectX 12), it can also evaluate CPU performance. 3DMark is an all-in-one solution, but it comes with a price tag.

FurMark is a stress-testing tool specifically for GPUs. It pushes your graphics card to its limits with a highly demanding "furry donut" rendering, helping you test stability, temperature, and cooling efficiency. This type of testing is often referred to as a “burn-in test.” Thanks to its signature rotating donut graphics, FurMark is jokingly nicknamed "the donut test."

Your PC works hard—whether it’s powering through work tasks, running games, or keeping you connected. But while we rely on our computers every day, cleaning and maintaining them is often overlooked. 

One of the biggest hidden threats? Dust. It builds up over time and can seriously impact performance and even damage your hardware. Let’s break down why regular cleaning is important, how often you should do it, and the best way to safely clean your PC.

Dust might not seem like a big deal, but inside your PC, it’s a different story. Dust buildup can block airflow, causing your system to overheat. When that happens, your CPU and GPU may throttle their performance to stay safe—meaning slower speeds for you. In extreme cases, it can even damage parts permanently.

Performance Drops, Hardware Risk, and a Shorter Lifespan

When fans and vents get clogged with dust, cooling becomes much less efficient. That means higher temperatures, louder fan noise, and increased wear on components. Plus, dust on the motherboard, graphics card, or RAM can lead to static discharge, corrosion, or even short circuits.

Shut down your PC and switch off the power supply. Unplug everything before you open the case.

Most cases have dust filters on the front, top, or bottom. These are easy to remove—some slide out, others are magnetic. You can rinse them with water or wipe them with a damp cloth. Just make sure they’re completely dry before reinstalling.

Remove the side panel carefully. With your compressed air can held upright, blow short bursts of air to clear dust from top to bottom. Focus on fans, heat sinks, and vents.

Use a soft brush to get stubborn dust off fan blades and heatsinks. It helps to hold the fan blades in place while using compressed air so they don’t spin wildly.

5. Be Gentle with the Motherboard and RAM

These parts are delicate. Use short bursts of air only—don’t brush them directly.

A microfiber cloth is perfect for wiping your hard drives, SSDs, and any other visible areas. Use compressed air to clean the PSU vents too.

It depends on your environment and how heavily you use your computer, but here are some general guidelines:

Keeping your PC clean isn’t just about looks—it makes a real difference:

How Often Should You Clean Your PC?

It depends on your environment and how heavily you use your computer, but here are some general guidelines:







Every 3 to 6 Months is a good rule of thumb for most users.



If you have pets, smoke indoors, or live in a dusty area, aim for every 2 to 3 months.



If you’re a heavy gamer or use your PC for demanding tasks, clean it more often due to higher heat output.



For light users in clean environments, cleaning twice a year is usually fine.







Why It’s Worth It

Keeping your PC clean isn’t just about looks—it makes a real difference:





Better Performance – Lower temps mean your system can run faster and more efficiently.



Longer Lifespan – Less heat and dust stress mean your parts will last longer.



Quieter Operation – Clean fans don’t have to work as hard, which cuts down on noise.

A little maintenance goes a long way toward keeping your system running smoothly, quietly, and for years to come.

Keeping Your PC Clean: How and When to Do It

When using the latest ATX 3.1 power supply, the most important thing to be aware of is the 12V 2x6 connector used for GPU power cables. Although this revised connector has significantly reduced the risk of connector burnouts, improper handling can still cause damage. Please pay special attention to the following points:

Connection Status Between Power Cable and GPU Connector

When connecting the GPU, ensure the direction of the cable and GPU connector matches. Also, confirm that the latch is fully engaged and locked in place.

Avoid Bending the Cable Within 35mm of the Connector

Whether installing the GPU horizontally or vertically, you'll likely need to bend the power cable. If the cable is bent too close to the connector, it can cause the plastic sheath near the connector to peel off, potentially leading to short circuits. It is recommended to bend the cable only after at least 35mm of straight length from the connector.

Do Not Force or Repeatedly Bend the Cable

While modern power cables are built to be durable, excessive force or repeated bending can still damage them, increasing the risk of electrical issues.
