Why Is My Projector So Loud? How To Fix It (Easily)

Having to figure out why a projector is so loud is not something you want to do at the start of a big presentation. Whether in a conference room or in your living room. A noisy projector can be distracting to viewers.

Projectors require active cooling to perform well. If a projector is installed in a setting where ambient sound levels are very low, its feedback-based cooling circuit may choose not to run the fan at all so it won’t be heard. But when there is no competing background noise and you hear your projector’s fan running, that means the internal temperature of the projector case has increased due to what can often be inefficient ambient room lighting conditions. Such as having projector lamps on for extended periods of time. There are ways to fix this and ensure that your movie night stays a silent night overall with properly placed projector screens as well as strategically positioned lamps themselves.

Fortunately, today’s technology has greatly improved the sound made by projectors. You’re less likely to hear it in all its loud glory. However, there will still be times when you will notice it is louder than you had previously suspected. There are many possible reasons for this. So the best advice to follow would be to thoroughly inspect your hardware components, check that your cables are working properly, and make some adjustments that were needed just to eliminate all possibilities because failing to do so could lead to further frustration and hassle.

Projectors are typically quite noisy machines. You’ll often see them in use at business presentations, conferences, or trade shows. However, if someone is planning to attend a meeting in which there will be a projector involved, then it’s always best to call ahead of time and let them know about the noise level so that they can dress appropriately for the occasion. Just make sure you note that even if the projector seems louder than usual. It’s probably due to something wrong with the motor controlling the fan or failing. But don’t worry – there are ways to get your machine back up and running optimally by having an expert come in and check things out for you. Remember though that technology is expensive but not necessarily cheap.

Why Is My Projector So Loud?

One of the main reasons why there can be too much noise is because the projector’s cooling fan might be starting to make noise. As many people know, fans are used for blocking light from escaping. However, a lot of times it does more harm than good as a result of its loud operation. One key way to fix this issue is by cleaning the room where it’s being used as this will help in ensuring that there is no debris or dust on the projector where these small particles tend to cause noticeable vibrations. Besides, another way to prevent vibrations coming from the machine is by making use of surge protectors which will block a large amount of loud noise produced by power surges.

Lubrication is a must for effective cooling in projectors. A projector uses control cards, a fan, a disc drive, etc. Which need maintenance and should be lubricated every year as there are moving parts within the device to help stop it from getting warm or overheating which would damage the equipment.

For that reason, the cooling fan operates to cool down your device’s internal components by creating a vortex. This fan can be noisy at times, but it should never disrupt what you’re doing. If it does become louder as you use your device, this means the cooling process is actually working better and so the fan is working harder to help your projector run at optimal temperatures.

Your projector’s ventilation system consists of two parts: the fan and air vents. Manufacturers may also install internal thermometers that trigger the fans to come on when it gets too hot inside your projector. Normal operation will involve letting cooler air in and blowing out hot air through the vents so your device never overheats.

As your fan blades turn, they can cause the other parts of your projector to wobble as well. This makes the noises you hear amplified. Because of this, here are some of the factors for the noise you are hearing:

  • Noice of motor fan
  • When the fan working your projector part is vibrating
  • Air circulation in the projector

How To Reduce Your Projector’s Noise:

Now that you know there’s a specific reason your projector makes so much noise, you’re able to fix it. For example, the problem might be a loos. Just tightening it will lower the noise, greatly improve how your product works and get everyone in the audience back on track.

1. Mount Your Equipment If Possible

Mounting your projector onto a wall or ceiling will give it more space to receive airflow, which can also help with cooling.  The bottom of the projector can often get hot, even if you don’t think so by looking at it, because of all the processes that are going on inside it. If your equipment is well-ventilated, then it will be easier for air to travel through it without a hiccup. That way, there is less of a chance that the fan will need to work too hard. The more room you can give your equipment to breathe comparatively speaking. However, the better off you’ll be! It’s important to remember that this isn’t an excuse for putting your equipment in an extremely high place though. You do still want the top section to have plenty of cool air circulating it during use as well as when being allowed time to cool down afterward.

2. Eco Mode In Projector

A new Eco mode feature is available on BenQ devices that allows you to prevent your projector from overheating or burning out its light source. The Eco Mode allows users to make a tradeoff between lamp brightness and fan noise, allowing them to keep the device’s interior temperature down at optimal levels in order for the engine not to overheat or the lamp to burn out. That way you will have a longer lifespan for your light source and won’t have to worry about it burning out during particularly intense moments of use.

3. Always Keep Clean Your Projector Clean

Cleaning your projector by cleaning wipes, cotton, or paper towels dabbed with alcohol are excellent methods. You can clean the outside of your device with spot cleaning. Do not use cleaners that contain ammonia or bleach because they may damage the finish on your unit in addition to possible scratches.

On the other hand, you can keep the internal part of your projector clean with a computer duster regularly. You can also use a soft brush to brush away dust from ventilation holes.

4. Clear The Place Where You Use Projector

If you cannot hook up your projector temporarily due to a component not working, you can remove the direction of airflow and use another fan as a replacement. The device must sit on a flat and firm surface with all sides cleared from anything. In addition, do not place it in carpeted or cushioned spaces. The reason is that such surfaces retain heat, which will make it more difficult for the fan to cool the device down. The best place to put your projector is an empty shelf, table or hard floor.

5. Place A Projector On The Cooling Place

Although it might sound like a niche product, there is nothing to stop the owner of a laptop from using a cooling pad on their laptop. However, before you do any such thing, it is essential that you check whether your choice of the cooling pad was actually created for electronics or not. When choosing one, paying close attention to things like how many fans are included and their sizes will help you make a better-informed decision. This then provides you with the necessary knowledge to work out just how much cooling power your laptop will get from them. As well as covering all bases so that your device is protected at all times during these stressful situations when working on it.

Even if a typical projector cooling pad has more fans, you don’t have much to worry about as they usually aren’t too noisy. They’re pretty quiet in fact, even when operating at high speeds. Still, you might hear the slightest bit of noise whenever you decide to lower the volume of what you are watching. That’s also because such pads typically utilize a fan that is being used for its cooling capacity rather than its blowing features. With that said, it’s important to turn down the volume every once in a while when using the device for long periods of time so as to keep your projector from getting hot and causing the fan to spin faster and make more noise in the process.

Look For Professional Repair:

Sometimes there are even simple things that can affect your projector’s performance, an example of which is dust. This is one of the few issues that are actually fairly easy to fix and despite their lack of seriousness, still might be what’s hampering the quality of your photos. So to consider this issue trifling would be a bit misguided. Instead, take account of it at once. Alerting others means your team members are more likely not to make the same mistake when they use your equipment next time.

Your projector will become damaged beyond repair if you don’t pay attention to the noises made by it. For this reason, you need to act as soon as you notice something unusual. There are also instances when the fan itself gets damaged and prevents it from working correctly, thus producing noise. If this happens to your projector, take it to a licensed technician for repair or replace the fan yourself if your situation requires you to.

What Makes Your Projector So Loud:

To address noise issues with your projector’s cooling system, there are a number of possible solutions. One option to explore is using shorter segments of the presentation and doing smaller chunks of the job at a time. For example, you can perform all the tasks needed to create your slides in a single sitting instead of distributing them out over several days or weeks which may lead to more time being spent on them each time and will often result in them taking longer than necessary to accomplish each task. This also helps prevent you from feeling overwhelmed by taking too much on.

1. Poor or improper ventilation

When placing your projector near a wall we suggest you put it as far back as possible to allow for sufficient space between the device and the wall. If you are facing a corner in your room, consider its placement so that the projector doesn’t overheat since this can cause your device to produce loud noises while it works to dissipate its heat. In addition to this, some units may be equipped with a cooling fan that helps send out warm air which could pose a serious problem if surrounding ventilation ports aren’t properly sized or aligned.

When using your projector, familiarize yourself with standard ventilation practices and the effect they have on how well your device functions by observing these simple steps: – We recommend that you always leave at least a 50 cm (20 inch) gap between the fan vent and anything that may be closer. When there’s no space for cool air to freely enter, the fan will need to do extra work to expel hot air from inside. To make sure it doesn’t overwork itself, simply allow for ample breathing room around the area of your projector. This important tip can help prolong any equipment you use in your business such as projectors or escalators for example.

Additionally, you need to be sure that your product is placed in a cool room. It would also be helpful to prevent it from being put near any other type of device or machine that generate heat.

2. Failing projector lamp

The projector’s lamp is the primary source of heat for your device. If you notice that the projector is overheating more than it used to, then this could be an indicator of a failing component. Overheating could cause the projector’s cooling fans to work harder and make more noise.

3. Issues

A rattling sound coming from your projector is one that you don’t need to disregard or ignore. It could mean that another problem within your unit is occurring, so this is something you’ll want to get checked out as soon as possible by a licensed technician. In some cases, a broken fan inside the projector or an electrical connection that’s failing can create a rattling sound.

4. Projector Is Used For Too Long

Using a projector for longer periods of time can lead to overheating, making the product noisy and possibly damaging. Make sure you turn it off now and then if you are going to use it all day because without a break the fan which cools the projector will have to work harder and may burn out. Not only will you significantly cut down on wear and tear, but your equipment will last much longer every time you follow this simple rule. Especially after replacing that faulty fan!


The last thing you want to hear when you’re watching a movie with your friends is a loud buzzing noise coming from the projector. In addition to the distraction, the noise can be enough to wake up the neighbors, which is especially problematic if you’re using the projector in your home. Luckily, there are a few steps you can take to get the sound down and enjoy your movie without the noise.
