How to fix Overheating and Noisy Laptop Fan issues

You can’t focus on anything you’re working on with a noisy laptop fan. The culprit for a noisy laptop fan can be one of the two usually – dust and overheating. If you’ve been using your laptop fan for years now, you would probably wonder why there’s a humming sound that is a far cry from white noise. It isn’t helping you concentrate – you’re getting distracted, and that has to stop.

Now, to get to the bottom of things, you have to determine why your laptop fan is noisier than usual. The cooling fan running at a fast and the non-stop rate could be blamed for this. It’s firing up or working harder than usual – churning like a wildcat – when it needs to get rid of heat or when it’s under the extreme workload. Even though your laptop is compact, it still is prone to accumulation of dust.  The clogged dust can wreak havoc on your laptop’s system which causes it to run hot and noisy. The challenge here then is how to cool down your laptop and zap the irritating noise.

Overheating Noisy Laptop Fan

If your Laptop fan is making weird grinding, buzzing or rattling noise when switched on, here are some ways to fix the noise and overheating Laptop fan issues.

Overheating Noisy Laptop Fan

1] Check the running processes: When your laptop is noisy, it could mean only one thing – it’s overworked. Check on your processes and see if there are running applications or programs that are CPU-intensive or require your CPU to grind harder than usual. Check if there are processes that are close to running at 100 because it could be the culprit. If everything looks good, then it could be the CPU fan itself which needs further checking.

2] Close the processes: Open your Task Manager and kill all running processes to stop your CPU fan from buzzing or whirring up in the effort to keep up with the demands of running programs like when you’re playing games or watching videos online.

3] Use a laptop cooler: Your laptop can only take so much heat before it goes bonkers. Using a laptop cooler is advised for those who use their laptop for gaming or work which means the laptop could be working hard for an extended period. You can choose between laptop coolers that have cooling baseplates and those that are clipped on the laptop to directly zap or suck out the hot air. These Laptop cooling software may interest you.

4] Clean your laptop fan: If all else fails, go right at the root of the problem. You can hire a professional to do the cleanup for you, or you can do this yourself. Dust and even hair could pile up and get clogged into your laptop fan which could reduce airflow. Cleaning it up would most likely solve your problem.

You need an air compressor and a small screwdriver to do this. Make sure that you take out the battery before you start cleaning to avoid static electricity. You should unplug the AC adapter as well. Unscrew the access panel to see the laptop fan. Blow out the dust using the air compressor. Make sure to do this outside of your home to avoid asthma or allergic reactions to dust.

Once you’re done, put everything back together and power up the system – you should have a quieter laptop now.
