3 Signs You Have a Dust Problem

Before you rush to open up your Apple device and void whatever warranties you might have, know that you probably don’t have a buildup problem unless you live in an environment with a lot of dander, pet hair, smoke, carpets that are rarely vacuumed, and so on.

But if you’re still worried whether your system is in danger or not, here are the three main symptoms of a dust problem that’s gotten so bad as to require immediate attention.

1. Unexpected Shutdowns

As dust accumulates on various internal components, it begins to affect air circulation. If air can’t circulate, heat can’t escape. If heat can’t escape, the internal equilibrium temperature will keep rising and eventually overheat.

At its worst, overheating can cause permanent damage to CPUs, GPUs, hard drives, and more. However, modern systems are good at detecting overheating and shutting down your hardware before things get out of control.

2. Slow System Performance

Another feature in modern computer parts, especially CPUs, is the ability to throttle performance when things get too hot. Throttling prevents the CPU from working too hard, which in turn generates less heat.

Few things are as frustrating as a throttled CPU as it will slow down everything on your system. If you feel like apps are taking too long to load or if your overall system feels slow or choppy, it may point to overheating.

3. Excess Fan Noise

As you Mac gets older, you may notice your fans getting louder and louder. You may also notice that they spin at top speed all the time. This could be due to a messed up system setting, but it’s likely being caused by overheating.

It makes sense, right? The fans are programmed to spin faster when the temperature gets hotter, so if they’re constantly spinning at top speed, excess heat could be the issue.

If you determine that dust truly is the problem, then keep reading to find out how to clean it out.

How to Clean Dust From a MacBook

Unlike iMacs, MacBooks always need to rest flush against a surface during use. As such, their vents are always sitting close to potential sources of dust. The problem is even worse for users who use their laptops on beds, blankets, carpeted floors, blankets, and other soft surfaces.

We recommend regular cleaning, at least once every six months for a low-dust environment. More often for high-dust environments.

Basic Maintenance

Before diving into the actual cleaning of internals, it should be noted that a basic maintenance routine can really help minimize how often you need to open up your Macbook. Keep these tips in mind!

  • Always use a hard surface. I know it can be very tempting to use your laptop in bed or on the ground — I do it from time to time against my better judgment — but you’re just exposing it to more dust that way. Use a laptop tray at least How To Make Your Own DIY Vented Laptop Tray How To Make Your Own DIY Vented Laptop Tray Read More ! Hard surfaces are better for air circulation, too.
  • Keep your house and surfaces free of dust. This one’s obvious but it’s amazing how many people neglect it. More dust in house, the more dust is sucked into the vents. Also, don’t use your MacBook in high-dust environments if you can help it.
  • Blast fan speed for 15-30 seconds. Using a program like Macs Fan Control, you can manually set your fan speeds. Some users recommend running them at max speed every once in a while to dislodge dust particles before they get caked in.

DIY Cleaning Method

For a full cleaning, you’ll want to open up your Macbook so you have access to all the nooks and crannies where dust can collect. Note that opening a MacBook can be risky, so do so at your own risk. We take no responsibility if something goes wrong.

Always turn your MacBook off before opening it up, and keep in mind that you will void your warranty — including AppleCare.

Pick your Macbook model from this list of iFixit repair categories to get model-specific instructions on how to open up the case. Specifically, look for instructions on opening the Lower Case.

Use compressed air to blast away bits of dust from every open crevice you can find. This is going to be messy so take the laptop outside if you can. Never use a vacuum cleaner for this task.

Reassemble the device and you should be good to go.

How to Clean Dust From an iMac

Warning: There is no easy way to access the internals of a 2009 iMac or later, which means you’ll need to disassemble the whole thing. Not only can this cause damage, but you’ll void any warranties you have. Do so at your own risk!

Fortunately, iMacs don’t collect as much dust as Macbooks do, so you don’t have to worry as much. In fact, a lot of iMac users have never once cleaned out dust from their machines yet everything still works fine. Your mileage may vary.

Basic Maintenance

Reassemble the device and you should be good to go.

Apple Service Center

If you know for sure that the internals need a good cleaning of dust but you aren’t comfortable doing it yourself, take it to a local service provider for Apple products. The Apple Store may even clean it out free of charge.

But even if it does cost something, the price may be well worth it. Not only do you clear yourself the risk of damaging your machine, but a simple cleaning could end up extending the lifespan of your machine significantly.
