How to Clean Laptop Fan Without Opening? Step By Step Process 2022

Opening a laptop to clean the fan is a precarious job. Not everyone wants to go that road. Thank God, we’ve compressed air can do away with clogged dust to let the fan take a breather. So, how to clean laptop fan without opening it? Try compressed air. 

When to Clean Laptop Fan?

Good question. Cleaning a laptop should be a part of your routine – if not daily, then once a week. But I’m not asking you to grab a Phillips screwdriver and open the bottom to reveal all the sophisticated internal or external components. I’m not telling you to get a scrubber and scrub the hell out of everything. No never. Just a simple dishwasher solution with a sponge to clean out the outer shell and a blower to do away with dust clinging to the fan. 

However, if your laptop time’s up and it’s too late that it’s making weird noises, it’s time to start cleaning. Besides that, here are the signs to look out for that indicate the potential warming up of your laptop. 

Laptop Heating Up Signs 

  • The fan starts making noises as if it’s cursing because of overburden. 
  • It takes more than your share of endurance to open a single Chrome tab. 
  • Besides Blue Screen of Death, you’re getting warning signs you never knew about their existence. 
  • Your laptop’s screen starts flickering. 
  • It shuts down without giving you any heads up. 
  • When you touch the bottom, it feels like you touched a hot saucepan accidentally. 

How to Check the Temperature of Your Laptop?

When you aren’t sure even after the symptoms of the grave disease of a faulty fan, you could check the temperatures manually. After all, stats do tell an irrefutable story. 

Download programs like SpeedFan, Core Temp, Real Temp, or CPU Thermometer to see at what point in the Celcius or Farenheit does your laptop’s core sit. 

Considering the temperature is soaring above 100 degree-Celsius, here’s what to do. 

Clean the Laptop Fans Without Taking The Chassis Apart 

Here comes the easier said than done way of cleaning the fan – using compressed air. 

Why do that? Because it’s convenient. You could find a can and a nozzle anywhere around your locality. Besides, it’s safer than other methods such as using blow dryers or taking the laptop apart with whatnot.

Why shouldn’t you use your mouth? 

Do you have compressed air in your lungs? I doubt that. But you can blow, right? It’s just don’t do that for obvious reasons. Internal components of the computers are electrically charged, even if that means a cooling fan. When you blow with your mouth, you’re not only blowing air but also minute droplets of water. 

That makes your lungs’ air quite humid for the poor fan. You may hear electrical noises when you do that. Besides, blowing into the dust and then inhaling to get more air means that dust is riding that air right into your lungs. You do know how many creatures thrive upon it, do you? You wouldn’t want them in. 

The Process

Step 1:

You may wanna shut down your machine because the compressed air would definitely interfere with the movement of the fan. That may aggravate the situation. 

Step 2:

Take a can of compressed air with an elongated nozzle. You need that nozzle to be able to drive the air home. Don’t miss any area. 

Step 3:

Find the air vents around your laptop. They could be at the back or to the sides. Normally, in notebooks, they are to the left, and in gaming laptops to the sides and back, depending on the model you’re using. However, if you’re unsure where they could be, check out your manufacturer’s manual. You may be using a model that has the latest cooling system that does not depend on fans at all. If you find that out, then there could be other problems with your machine other than a faulty fan. 

Step 4:

Hold the can in your hand and direct the nozzle to the vents. Press the nozzle to let out a strong gust of compressed air. You should see dust blowing out from the other end. That’s good news. 

Step 5:

Some laptops come with wider vents. That makes it easy for the nozzle to reach out to the blades of the fan. Don’t shy away from doing that. However, at this point, you may wanna hold the nozzle at 45 degrees so that you’re not pumping the dust further inside. 

Step 6:

Clean the sides where the dust has visibly settled down after you blew it off with dishwasher soap solution and a sponge. 

Step 7:

Make sure the vents aren’t blocked by anything before you turn on the machine again. You should see excess dust coming out of the exhaust vent when you do that.

Step 8:

If there’s a visible improvement, repeat the process two more times to seal the deal. 

How do I clean the dust out of my laptop fan?

The optimal way to blow dust and debris out of your ventilation fans is to use compressed air spray, or you can use a microfiber cloth and isopropyl alcohol to melt away grease that’s clogging them.

How do you clean a fan without opening it?

The bottom or right side of most laptops has hidden ventilation ports to dissipate hotter air. You can use compressed air to remove any dust in the airways that have been lying there.

Can I use a hairdryer to clean my laptop?

The use of a hairdryer is the worst idea because two things can happen: first, it can damage the sensitive parts through high-pressure air, and second, it can build up static electricity, which could damage the hardware.
