But then it doesn't stop. And the laptop fan gets even louder. Then, it won’t shut off.
The fan is so loud that you cannot hear Netflix even on full volume: an evening ruined. And to boot, you’re now worried that something is wrong with your laptop.
So, why is your laptop fan so loud? Several factors could be the culprit of a noisy fan, including the most common factor: dust. Read on to determine six possible reasons that could be the cause of this noisy nuisance, as well as some standard troubleshooting and resolutions.
Dust is the number one common culprit of a loud, running fan. Because laptops are so compact and designed to be as slim as possible, there’s not much room for airflow resulting in an easily clogged cooling system.
Laptops typically have one or two fans to cool the central processing system. You can imagine that if the fans are unable to function correctly to cool down the processing system, compromised by dirt and dust, the significant damage it could cause to your laptop as a whole. Only by keeping a clean laptop (inside and out) can you avoid dust-related damage.
Cleaning Your Laptop
You’ll need to dust the laptop cooling system at least once a year to ensure that it remains somewhat clean to prevent any damage or degradation.
It’s important to note that although the user can clean and maintain a laptop by merely removing the panel (on the bottom of the computer) with a screwdriver, some laptop models are not designed to be opened by users.
- Power laptop down.
- Remove the laptop battery (if possible).
- Insert compressed air nozzle into the laptop vent.
- Press a long, thin plastic object against the laptop blades so they won’t spin (spinning blades won’t clean thoroughly).
- Begin blowing out the dust.
Alternatively, there are several tutorials on how to take apart particular laptops models. If you do own a laptop model that can be opened by the user, it’s preferable to use a small brush to clean out the dust and dirt instead of compressed air. Furthermore, if you can open the laptop panel, it might be best to remove the fan to clean any dust or dirt left behind the blades.
Although it seems like it could plausibly work, using a vacuum cleaner to remove dust and dirt from a laptop is not ideal due to the static electricity build-up that can also cause damage to your device. Stick with compressed air and brushes.
Replace the parts you’ve removed after you’ve completed cleaning the fan and surrounding areas.
#2: Ineffective Hard Drive (and its Impending Doom)
An overworked fan and hard drive can sound similar to one another. In other words, you may think your laptop fan is making all the ruckus when it’s your hard drive making the noise.
Both fan and hard drive make a whirring sound. However, a hard drive issue will have accompanying noises: clicking and grinding.
Unfortunately, when the hard drive begins to make these noises, it is most likely due to failing mechanics within the hard drive itself. Consequently, the hard drive will need replacement.
#3: Plastic Fan Bearings Need Replacement
Rest assured that the plastic fan bearing is not meant to last forever, nor are they a typically expensive part. Bearings are a small part and cost anywhere from $10.00 to $20.00, depending on your laptop model. However, the real cost is the labor-intensive work of determining the proper part, then installing it.
Before ordering a new part, it’s crucial first to access your laptop fan to determine the dimensions you’ll need. Alternatively, you can check with the seller to obtain accurate information regarding the proper part to purchase.
Furthermore, an alternative to replacing the fan is to purchase a cooling pad (which costs anywhere from $20.00 to $70.00). A cooling pad can stop the inner fan from running but will achieve the desired result: cooling the internal systems avoiding damage.
The plus side of solving this issue with a cooling pad is that you don’t need any specific parts, just the cooling pad itself. If purchasing a cooling pad is the route you choose to go, check out the highest-rated (4.6 out of 5 stars) Pccooler Laptop Cooling Pad. It’s top-quality and only priced at $25.99.
#4: Apps & Software Straining CPU Resources
If your laptop fan is running at top speed, or the fan won’t stop running, you’ll need to check to see if any of your apps are using a high percentage of CPU time. Luckily, this issue is easy to fix and doesn’t require any funds.
The CPU time is the amount of time that the central system used for processing information from a new operating system, app, or software. In other words, it is how hard the laptop system is working.
The more CPU time utilized, the harder your laptop is working. The harder your laptop processing system works, the risk of overworking it increases, resulting in a noisy fan trying to cool the overworked system.
If you don’t believe that your CPU time has reached its highest capacity, it’s possible that malware could be to blame. Cryptomining malware hijacks your laptops CPU time to mine cryptocurrencies (digital or virtual currency).
To reduce the amount of CPU time utilized (and thus decreasing how hard your systems are working, and hopefully how hard the fan works), you’ll need to locate your task manager in your laptop.
Then, find the “processes” tab, then the “CPU” tab. You’ll then be able to monitor the apps, software, and systems (including any Malware) that are using the most CPU time to remove or replace.
#5: Missing or Damaged Rubber Feet
Those little rubber feet under your laptop do more than keep the computer from sliding around on your desk. Although the rubber feet are a small and simple addition to your laptop, they are just as critical for the functioning of your computer as the hard drive and fan.
How? Rubber feet for your laptop extends the life of your laptop. Your laptop fan could be functioning correctly, but without any airflow to the fan, it will not work properly anymore. Rubber feet prop up your laptop just enough to allow airflow to the laptop fan.
So, if you find your laptop fan making loud noises and see that the rubber feet have peeled off the bottom of the laptop, this may be the culprit.
The rubber feet assembled by laptop manufacturers can be of lesser quality than rubber feet you can purchase separately. Laptop Lifts offer high-quality, low-cost ($19.95) rubber feet that guarantee not to slip or peel off.
#6: Fan Setting
Some third-party software programs will allow most laptops control over the fan settings. If you can control the fan setting, then you can control the fan noise.
However, if there is a valid reason your fan is working overtime to cool your laptop systems (as some possible reasons above detail), reducing the fan speed (to minimize fan noise) will increase the heat within your laptop. Reduced fan speed = increased heat generated.
Consequently, although you are resolving the issue of decreasing the fan noise, you are simultaneously increasing damage to the device itself by overheating it. Thus, although it’s an option to resolve your noisy fan predicament, it’s not the most desirable resolution when weighing the risks.
Attempting to troubleshoot the systemic issue of a loud laptop fan yourself is ideal. Immediately running off to a local repair shop or manufacturer, before trying to resolve the situation yourself, can accrue unnecessary expenses.
You could end up paying $50.00 to $100.00 per hour for just the diagnosis alone. And if the determination results in bad news for you and your laptop, you’ve just added a brand new laptop to your bill on top of it.
However, if these solutions do not decrease your laptop’s fan noise, it may be worth it for your laptop to see a professional. It could be indicative of a more severe problem that needs addressing before further damage accrues. Alternatively, depending on your laptop model, it may be more cost efficient to buy a new laptop as opposed to mending your current device.
Hopefully, these six possible reasons for your noisy laptop fan and resolutions assist you in resolving this inconvenient nuisance.
