What went my CPU cooler is so loud?

Several things can cause your CPU cooler to make noise. Most of the time, it’s because the fan inside the cooler has picked up too much dust and dirt. Aside from that, it’s normal for a cooler to get loud when it’s working twice as hard.

This is nothing to worry about, because I had the same question you do right now and figured out the answer. I will tell you more than one way to fix your cooler so that it works again.

As a tech lover, I’ve tried all of these solutions over the years.

So, let’s skip the waiting and get right to the content. Just make sure you don’t miss any of it while you sip your coffee.

Why Is My CPU Fan Loud?

When a system gets too hot, a fan on an overheated system makes the fan blades spin faster (Rotations Per Minute). Wires from an internal part could be touching the fan blade, which could be another reason. When using the PC, this can make a loud and annoying noise.

How to Make a Loud Fan Less Noisy?

If your fan is making a lot of noise because your CPU is too hot, lowering its temperature may make the fan quieter on its own.

Try doing what you need to do to cool down your CPU before trying any of the solutions below.

Clean Your CPU Cooler

I’ve already said this, but people, including me, tend to forget every few weeks or so to clean the dust off the CPU fan.

Since the airflow makes it natural for dust to build up, it’s a good idea to make a schedule for cleaning and maintaining your CPU.

This dirt can make the fan louder and move more slowly, which slows down the computer as a whole.

So, is it as easy as taking a brush and wiping everything clean like anything else? Well, no, that’s not how you clean a computer. Instead, it would be better if you could get a can of compressed air.

Then, all you have to do is use short bursts of compressed air to blow the dust off of the internal parts, especially the fans and heatsinks.

End Background Processes

The first thing you might want to try is to use the Task Manager to end all background tasks. When your CPU is being used a lot, it will get hot. Because of this, the CPU fan will spin faster than usual. And this makes the CPU fans make more noise. Remove any extra background to see if it makes the fan quieter.

  • To open Task Manager, press Ctrl + Shift + Esc.
  • If the Task Manager shows a list of running programs without any details, click on More Details.
  • Click on the process that is using a lot of CPU resources and then click on End task.

Maintain Good Airflow Inside the PC

If your fans aren’t able to move the hot air out of your PC properly, they might start running faster.

Make sure that your computer, whether it’s a laptop or a desktop, is on a smooth, flat surface like a desk or even a tiled floor. But you shouldn’t put it on carpet, in a drawer, or in a cabinet.

The goal is to make sure that your computer’s hot air has somewhere to go while your fan works to get rid of it.

Also, I know that laptop users like to put their laptops on their laps when they use them, and that’s fine as long as you take a break every so often.

  • Take care of the cables inside.
  • Clean the vents and fans in the computer case

Replace a Loud (or Failing) Fan Entirely

If none of the above fixes work, your fan may need to be replaced. Even if a fan is in good shape, it can be too loud at times.

Smaller fans tend to be noisier, so if you have a 90mm fan that you can replace with a bigger one or get rid of entirely without changing the temperature, that’s a good place to start. The bigger fan will not only be quieter, but it will also get rid of heat better because it has more fins.

CPU coolers, which can be either air coolers or water coolers, are a popular way for custom builders to keep the processor cool. If your CPU heatsink is small, switch it out for a bigger one.

Sometimes, a fan is headed for a dusty grave. This can often cause annoying noises like clicking, buzzing, or grinding. You might be able to fix this by putting a drop of sewing machine oil in the bearing, but you should do this before you notice anything wrong. If this doesn’t work, you may need to get a new fan.

Why Is My CPU Cooler So Loud

When looking for a new fan, pay attention to the “CFM” and “dBA” numbers in the specs. The “CFM” number tells you how much air the fan moves, and the “dBA” number tells you how loud it is.

You can keep your PC from sounding like a jet engine in a few years by using the right fan and doing some preventative maintenance next time.

Underclock CPU

An overclocked CPU will work much better than one that isn’t fast enough. But one problem is that the CPU will get hot pretty quickly. So, to stop this rise in temperature, we speed up the CPU fan. And making the CPU fan louder as a result.

If you have overclocked your CPU, you should lower its speed to reduce the amount of noise produced by the CPU fan.

Lower Fan Speed

You can also try to slow down the speed of the fans by using Fan Control software or the BIOS. If you slow down the fan, it will make less noise. But if you turn down the speed of your fan, your computer may get too hot.

Here are the steps to use the BIOS to slow down the speed of the fans.

  • To get into the BIOS, press the BIOS key over and over during startup. Most of the time, this key is the Delete key or one of the function keys.
  • Look for Cooling or Hardware Monitor in the list of settings.

  • Save and leave the BIOS once you’ve set the RPM you want.

Check CPU Fan’s Connection To the Motherboard

If the computer’s CPU fan is not connected to the right fan header on the motherboard, it may spin at its maximum RPM.

The thermal sensors work with the CPU fan header on the mother board. This lets the system change the RPM of the CPU fan based on how hot it is. So, if you connect the CPU fan to a different header, the CPU fan can’t be controlled. And it will spin as fast as it can, which will make it louder.

Make sure the CPU fan’s cable is plugged into the CPU FAN header on your motherboard.

Clean the CPU Heat Sink

A dusty heatsink doesn’t do a good job of letting heat from the CPU escape. When the fan’s RPM is set to the default, it doesn’t cool the heat sink. So, when the CPU temperature goes up, the motherboard speeds up the CPU fan to cool it down.

So, unless you clean the heat sink itself, your CPU fan will keep going faster and faster. You can clean the spaces in your heat sink with a can of compressed air.

Upgrade CPU

In conclusion, an obsolete central processing unit (CPU) could require a lot of resources, which causes it to operate at extremely high temperatures. Because of this, the fans on the CPU will be operating at a high rate of rotation. As a result, the fan will be loud.

Although it is possible to resolve this issue, upgrading to a more recent version of the CPU chip might be quite pricey. Your personal computer’s performance can be improved by upgrading to a more recent generation of CPU chips without requiring a significant increase in computing power.

Conclusion:

When you hear loud noises coming from your computer, it may be both bothersome and terrifying at the same time. But, the issue can typically be resolved if you keep in mind the importance of having some patience and hunt for the solution in the appropriate location.

FAQs about Why Is My CPU Cooler So Loud

Why Is My CPU Cooler So Loud?

Your computer’s fan is loud because the temperature inside is too high. This can be caused by using all of the disk space, using a lot of RAM, having dust and dirt in the vents, or not enough airflow.

Are CPU air coolers loud?

Noise: Air coolers use heat sync fans to pull heat from the CPU and case fans to get rid of heat from the surrounding air. This makes the machine noisier.

What are the benefits of a CPU cooler?

CPU coolers are the best way to get rid of the heat made by the system and make sure you get the best performance from your PC. They not only keep your system cool, but they also make it work better, so you don’t get any hiccups or delays.

Why does a cooler make noise?

If your cooler makes noises like rattling or bubbling, you should first check to see if the noise is coming from the pump. Turn off your fans or set them to 0% duty cycle to stop the noise. If your cooler pumps keep making noises, there may be air bubbles stuck in the cooling loop.

How loud is a CPU fan?

At full load, your CPU cooler can be one of the noisiest parts of your computer. Some models can be as loud as 60 or 70 decibels or more. This happens more often with power users who want the processor to work quickly. The CPU gets hotter and needs more cooling as it works harder.
