It is common to have dust cover up the insides of a computer case. What’s important is knowing how often to clean your PC to keep up the optimal performance of your system and prevent frustrating issues like lags and slower speeds.
Key Takeaways
- Your PC can face overheating issues if you do not clean it often, which may reduce the components’ lifespan.
- Cleaning the PC occasionally can reward you with good performance and riddance from overheating.
- Air filters, cleaner surroundings, and distance from pets can help keep your PC clean for longer.
In my experience, it’s crucial to clean your PC every 3 to 6 months, although the frequency might vary depending on where you live. If you’re in an area with polluted air, you might notice dust accumulation within just a few days after giving your PC a thorough clean.
Even in cleaner environments with less dust, it’s still important to regularly open up your PC case and inspect the components. Despite the absence of pollution, there can still be unwanted substances that need removal to ensure the safety and longevity of your PC’s components.
I mostly use compressed air cans to remove dust from the hard-to-reach areas of my PC and the components. The nozzle is narrow and conveniently blows off layers of dust. However, if you do not have an air can, read how to clean a PC without compressed air.
Importance Of Cleaning A PC Often
Not cleaning your PC causes dust and debris to build up, ultimately affecting its overall condition. Not only does it harm your components physically, but it also can snatch their ability to perform the assigned tasks.
These are all the problems you may encounter for not cleaning the PC timely:
- Slower Performance: Resource-intensive tasks become sluggish, such as gaming, high-resolution movie streaming, or loading multiple tabs simultaneously.
- Overheating: Dust settles in the PC fan bearings, over the processor, and other components, impeding the fans’ ventilation function. The heatsink also struggles to radiate heat off the processor effectively. As a result, components exert extra effort to maintain task performance while managing temperature. Meanwhile, learn about a good PC case airflow setup for optimal cooling.
- Polluted Surroundings: As your PC heats up, the fans work harder to bring in cool air, attracting surrounding dust earlier than usual.
- Reduced Lifespan: With problems like overheating and dust build-up, the original lifespan of the PC and its components may be reduced.
Which Components Of The PC Should Be Cleaned Often?
Here is a list of essential components I clean every once in a while to prevent unwanted PC troubles. To make things easier for you, I will briefly explain the cleaning technique for each.
Monitor
Use an air compressor can or alternatives to clear dust from the monitor’s input ports. After clearing the dust, I wipe the monitor with a damp cloth to eliminate any stubborn mess.
Fans
Fans hold much dust as they are the ones that do all the air work in the first place. Therefore, you need to clean PC fans to allow smooth functioning. I use a cotton swab dipped in rubbing alcohol for tough dust. A damp cloth will also work fine. Once the fans are clean, you may attach them back into their respectful place.
Motherboard
After you have opened the computer case, unscrew the motherboard and detach the heatsink. Clean the motherboard carefully to remove any accumulated dust. After cleaning, I applied a new thermal paste on the heatsink before re-attaching ck to the motherboard so it sticks firmly. However, make sure to clean the old thermal paste completely before putting on a new batch. Also, check out how long thermal paste lasts so you can replace it timely.
Graphics Card
To clean the graphics card, again, use a compressed air can. Carefully make sure to blow off any dust that is covering the GPU slots and its heatsink. Plus, you can use our guide to fix the graphics card overheating issue.
PSU
I recommend cleaning the PSU using an air compressor. Set the correct pressure and keep it at a distance of at least 2 inches. Blow the air into the holes already present on the PSU’s sides and through the fan. Ensure to keep blowing the dust off until none comes out of the PSU. And know how long power supply units last to know when they require a replacement.
How Do I Protect My PC From Catching Dust Soon?
Here are some tips you can keep in mind so that your PC does not catch dust sooner than it should:
- Keep it out of pets’ reach, as their furs can likely block the fans from spinning if it gets between them.
- Get an air filter to prevent dust and debrom entering your computer case.
- Keep your PC in a closed room, preferably with an AC; this will help your PC not get covered up in dust and not heat up quickly.
- Maintain clean surroundings of your PC.
As someone who cares about their PC, I always ensure it is free of any impurities. Additionally, while cleaning the PC, I was careful not to damage any sensitive areas. If you give your PC the care it needs, only then will it be able to provide you with a good performance. The lack of care can turn into quickly become a big expense.
Frequently Asked Questions
You can use a microfiber cloth and even a soft toothbrush or paintbrush to clean the dust off the components of your PC.
The reason behind fans being noisy is that they have to put in extra effort to maintain the temperature inside the computer case as it becomes too high when all the components start to overheat.
The reason why the dust is so sticky and stubborn is due to moisture and emissions from vehicles that are present in the air. It causes the components to look like they are greasy.
