How to clean hp laptop fan without opening

Are you having problems with your HP laptop fan? Does it seem to be running slower than usual and making strange noises? If so, don’t worry! You can clean and maintain your laptop fan without opening the device. In this blog post, I’ll show you how to easily clean your HP laptop fan without taking apart the device.

Step 1: Power Down and Unplug Your Device

Before you get started cleaning your laptop fan, the first and most important step is to make sure your device is powered down and unplugged from the wall. This will prevent any damage or shock that might occur during the cleaning process. Make sure that the laptop has completely cooled down and that all its lights have gone off before proceeding. Once you have confirmed that it’s safe to proceed, you can begin cleaning your fan.

Step 2: Locate the Vents

Once your laptop is powered down and unplugged, you can begin the process of cleaning your HP laptop fan. The first step is to locate the vents. These can usually be found on the bottom or side of the laptop. Once you’ve located them, it’s time to start cleaning.

Step 3: Use Compressed Air to Clean the Dust

After locating the vents, the next step is to use compressed air to clean the dust. Compressed air is a cheap and readily available option that provides a safe way to clean your laptop fan without taking it apart. When using compressed air, be sure to use short bursts and keep the can upright to avoid condensation inside your laptop. Aim the can into all of the crevices around the fan blades and any other openings to help blow away any dust or debris. Make sure you keep a good distance between the fan and the can of compressed air to avoid damaging any delicate parts.

Step 4: Take the Fan Outside and Spray It with Soapy Water or Simple Green

Once you’ve removed the dust from your laptop fan, the next step is to take it outside and give it a good cleaning. To do this, you’ll need to spray it with soapy water or Simple Green and then rinse it off with a hose. This will help loosen any stubborn dirt and debris that may be stuck on the fan blades. Be sure to allow the fan to dry completely before turning it back on, as any moisture left behind could damage the laptop. Taking the fan outside and giving it a good rinse is an important part of keeping your laptop running smoothly.

Step 5: Spray the Fan with a Hose to Wash It Off

After taking the fan outside, I used a hose to spray it down, ensuring to focus on the areas I sprayed with cleaning solution. This helped to wash away any residual dirt or dust that was left behind. Be careful not to use too much pressure when spraying the fan, as this can cause damage to the delicate components. I made sure to keep my distance and to angle the spray away from any other parts of my laptop so as not to cause any further damage. I then allowed the fan to dry completely before turning it on again.

Step 6: Allow the Fan to Dry Completely Before Turning It On

Once the fan has been washed off, it’s important to make sure it is completely dry before turning the laptop back on. If you don’t take this step, you risk damaging your device. To make sure your fan is completely dry, you can use a soft, lint-free cloth to gently dab away any excess moisture. You can also leave the fan outside in a warm and dry area to ensure that it is completely dry before reassembling the laptop. Make sure to pay attention to all those small crevices and hard-to-reach spots when cleaning and drying your fan so that all the dust and dirt are gone and your laptop will keep running smoothly.

Step 7: Spray Compressed Air Into the Vents in Quick Bursts

In the previous steps, we discussed different ways to clean your HP laptop fan without opening it. Once you are done with the cleaning process, it is time to spray compressed air into the vents of your laptop. Start by keeping the laptop closed and flipping it over so the bottom points up. Aim the compressed air nozzle at the vent, but do not push deep inside it and give a short burst of air. Target another vent and do the same. This way you can keep the dust and debris out of your laptop while cleaning its fan. Make sure to use quick bursts of air to avoid any condensation buildup inside your laptop.

Step 8: Avoid Putting Continuous Air Into the Intake Vents

When cleaning the fan of your HP laptop, it is important to avoid putting continuous air into the intake vents. Doing this could create condensation inside the laptop, which could lead to electrical problems or damage. Instead, use quick bursts of compressed air to blow out any dust and debris from the vents. Additionally, you can gently clean very dusty areas with a dry microfibre cloth. For a small business with limited resources and tight deadlines, malfunctioning laptops could be disastrous – so taking the time to clean your fan is a good way to ensure that your device stays in top condition.

Step 9: Gently Clean Very Dusty Areas with a Dry Microfibre Cloth

Once you’ve finished cleaning the fan and the vents, you’ll want to make sure that any dust or debris that’s still lingering around is cleared away. To do this, you can use a dry microfibre cloth to gently clean any very dusty areas. Fold the cloth and rub it lightly across the full width of your device, back and forth. Make sure to brace the laptop with one hand while wiping it with the other. This should help remove any remaining dust particles that may have been left behind. By taking these extra steps, you can ensure that your laptop’s fan is kept in top condition.


In conclusion, cleaning your laptop fan can be an easy task if you follow the right steps. First, make sure to turn off and unplug your laptop before you start the cleaning process. Then, locate the vents in your laptop and use compressed air to clean away any dust that has built up. If your laptop is extra dirty, take it outside and spray it with soapy water or Simple Green and then rinse it off with a hose. Finally, use a dry microfibre cloth to gently clean very dusty areas. Following these steps can help you avoid dust build-up and keep your laptop running smoothly.
