Do SSDs Get Hot? [Explained]

As the demand for secure and reliable data storage devices increase, Solid State Drives (SSDs) have skyrocketed in popularity. 

Today, people prefer SSDs over HDDs as SSDs are more efficient and quiet. Add to that the price drop in SSDs we have seen over the years, and that has created a whole new wave of SSD users. 

In fact, we can even see people who are not really tech savvy get a new SSD in the market right now and they have tons of question about it. One of these questions is regarding the temperature that an SSD can reach.

You’d be surprised to know that SSD can get very hot despite the fact that it lacks moving parts. But exactly how hot does it get? And What can you do about it?

In this blog, we are going to answer these questions and provide a complete breakdown of SSD temperatures.

So, let us start!

Do SSDs Get Hot? Temperature Limit Basics

SSDs don’t have moving parts, but they are electric components made up of chips. When you write and read data to and from an SSD, the computer passes electricity to the SSD.

And where there is electricity, there is heat as Heat is a normal by-product of any functioning electrical part. 

The more you use an SSD, the more heat it will produce. Why? Here are the two reasons:

  • The first reason is obvious – Electrical energy coursing through an SSD heats up the circuitry. So, when a computer uses an SSD to its full potential, it needs to pass more energy to the storage device, and this creates more heat. 
  • The second reason is their size – Just think about CPUs and GPUs; they are not crammed in a case and have ample airflow. But they are still very hot. On the other hand, SSDs don’t really have that luxury. They come in small sizes and have zero airflows. So, it’s no wonder these little guys get hot! 

What Temperature Does an SSD Usually Hit?

SSDs typically run at a temperature of 0 – 70 degrees (in Celcius) and 32 to 158 degrees (in Fahrenheit). This temperature range is standard for all the consumer SSDs that are on the market right now. 

But sometimes, the range can vary. For instance, a 2.5-inch SATA SSD might run a bit cooler than an M.2 mSATA SSD.

Having said that, the 70-degree temperature is generally within the operating parameter of most SSD manufacturers. 

Even so, SSDs run a bit cooler than the maximum temperature. In fact, most SSDs run at 30 to 50 degrees for better reliability. 

This temperature range may vary on factors such as

  • Your location and Environment temperature outside. 
  • Temperature of your room.
  • Read/Write the state of your CPU. 
  • SSD’s enclosure, airflow, and the overall temperature of your CPU case. 

Let us now look at the CPU temperatures in two states:

  • Idle State – The SSD is doing nothing
  • Full Load State – The SSD is doing heavy read/write operations.

‘Hot’ vs ‘Hot Enough to Be A Problem’- What’s The Difference?

It might not make a difference to your day-to-day tasks when your SSD is hot. If it runs at a range of 30 to 70-degree celsius, you don’t really have to worry.

But once it crosses that 70-degree threshold, you could see some problems. Having said that, most SSD manufacturers have safety features like thermal throttling. 

What’s that? Well, thermal throttling is a process where electric components sacrifice performance not to let a device exceed a certain temperature threshold. 

This means you will see decreased read/write speeds on your SSD if it is running extremely hot.

Here’s what happens when your SSD is ‘hot enough to be a problem’ 

  • The SSD enters thermal throttling mode to prevent it from getting too hot.
  • The SSD will slow itself down to almost a halt. 
  • When the temperature is dialed back to a cool enough range, the SSD will switch itself on, and you will get your read/write speeds back. 

So. whenever you are having problems with your SSD slowing down, just have patience. It might be because of extreme temperatures.

Why Can SSD Temperature Go Unusually High?

There are many reasons for an SSD to get extremely heated. Most of the time, it happens when there is a combination of reasons. 

We have covered the main reasons below:

Bad Airflow

When your SSD is located in a low-airflow spot, it increases the chances of heating up.

While this might not be an issue for a Desktop CPU Case with ample cooling, laptop SSDs generally aren’t that lucky when it comes to Airflow. 

Most SSDs come with an enclosure, but these enclosures can be a double-edged sword. 

Many of them can help keep an SSD cool, but a big fraction of these SSD enclosures will not let any air in, which will only heat up the SSD. 

Heat from Other Components

Often, SSD gets heated when other components in the case get hot. We can see this happen especially in Laptops where we need to pack in many components in a tight space. 

Thin ultrabooks with super powerful CPUs generally heat up as their design doesn’t allow much airflow to the motherboard. As a result, the whole board, including the SSD gets heated up. 

Manufacturer Problems

Some of the SSDs run hot by default due to some issue in their manufacturing. We can see this problem in mostly off-brand Chinese SSDs. 

If you are getting an SSD from a well-known company like Kingston, you don’t really have to worry about manufacturing defects. Even if you do, you can always claim a warranty. 

Environmental Factors

Environmental factors such as a poorly ventilated room, dirt, and dust clog up the internals of your system and creates bad airflow. This, in turn, increases the heat inside your machine, and SSDs will have to bear the brunt. 

Even your climate can impact the heat of your system. If you are living in countries along the equator with no Air Conditioning, heating issues galore! 

5 Ways to Keep SSD Cool

While SSDs don’t normally overheat, you should still try to keep it cool with the following five ways: 

Use fans

Both laptops and desktops come with fans, which help to keep these devices cool. Fans do this by ensuring maximum airflow inside your computer case. When it has excellent airflow in your computer, your SSD will naturally benefit. 

In the case of desktops, you can add as many fans as the case permits you to. You can also use alternative cooling options like liquid cooling in desktops (if you have the budget).

Things get a little tricky when it comes to laptops. You can definitely not add any extra fans in a laptop but one thing you can do is increase fan speeds (in both laptops and desktops).

With laptops, you could also use coolers which are elevated surfaces with two fans that will pump air into a laptop’s vents. 

These coolers are very affordable and can provide some much-needed cooling to your hot-as-hell laptop! 

Relocate Your Device

As we mentioned earlier, the environment plays a crucial role in determining the temperature of your SSD. When you live in a dusty, poorly ventilated, and hot room, computer parts are sure to fail. 

So, make sure your devices are located in an appropriate room.  You need a cooler or air conditioner if you live in a hot country or state. And also, make sure you cover your devices with a thin cloth if your room has too much dust. 

Try another SSD Enclosure

SSD enclosures are made up of various materials that heat up at different temperatures. So, if you can find an enclosure that’s a bit cooler than the one you already got, go for it. 

Get An SSD with a Heatsink

While NVMe SSDs don’t produce that much heat, and you can get away with not installing one a heatsink, it is better to install one on normal types of SSD.

You can buy a heatsink separately from a computer shop and install it yourself. But it does cost quite a bit. Even so, your investment won’t go to waste. 

A heatsink basically redirects the flow of heat away from the SSD, it filters out the heat without affecting the performance of the device. If you are running a large computer program, such as a high-end game, from your SSD, we recommend you install a heatsink.

Proper SSD Health Maintenance

You need to ensure your SSD has proper health. SSDs can get slow and hot when there is too much dust accumulation, computer viruses, and other complications.

Also, don’t defragment your SSD all the time. Defragmentation is the process of creating sub-drives from an SSD. 

Let’s say you have an SSD of 1 TB, you can defragment it in 4 drives of 250 GB each or 2 drives of 500 GB each or in any other way you want. But make sure you are consistent with this division and don’t repeatedly re-defragment the space!

When You’d Understand If Your SSD Has Gone Bad

When your SSD is on its last leg, there will be clear signs.Here are a few of them:

  • First, you will have frequent slowdowns and lags. Second, you will see that your SSD keeps on freezing while transferring data. And finally, even common applications will start running tremendously slowly. 
  • Sometimes your operating system won’t boot, and this typically comes with an error message like “No bootable device” or “No bootable medium” error message on windows. In the case of Mac devices, you will see a flashing question mark on the screen. 
  • Occasionally, you will see the dreaded Blue Screen of Death, and your computer will randomly restart.
  • There are also some instances when a failing SSD becomes ‘Read Only,’ meaning you won’t be able to download or copy any file(s) on it. But this normally happens when your SSD is infected by a computer virus. 

When you encounter these problems, it’s high time you start to fix the SSD. Make sure your devices are clean, the airflow is correct, and your SSD has proper health.


Do SSDs need a cooling fan?

No, SSDs don’t really require a cooling fan, unlike other PC components like CPU and GPU. But if your case has a cooling fan, it will definitely keep your SSDs running a lot cooler. 

How hot should my SSD get?

The ideal temperature for an SSD is 30 to 70-degree celsius. If your SSD temperature is in this range, you don’t have to worry about 

Do SSD or HDD get hotter?

Hard Disk Drives have rotating motors that spin at 15,000 revolutions per minute. This motion results in heat. But the heat is limited to 25 to 45 degrees celsius as HDDs are not crammed in a tight enclosure. SSDs, on the other hand, operates at a temperature of 30 to 70-degree celsius. 

Can SSD be damaged by heat?

Yes, every SSD has its own heat threshold (the typical range is 30 to 70 degrees celsius), when an SSD crosses this threshold, it starts throttling, and if it frequently exceeds this temperature limit, an SSD can get heat damage. 

How do I know if my SSD is hot?

Your SSD won’t work like normal if it is too hot. You will see slowdowns in read and write speeds, and your Operating System, Games, or any Application you are using may start lagging. 

Final Words 

It might be hard to pinpoint why a certain SSD is overheating exactly. Reasons can range from heavy workload, lack of airflow to heat from nearby components, manufacturing defects, and more. 

But whatever the reason might be, you need to fix your SSD’s overheating issue before it’s too late. You can do this by following the methods we have mentioned above. 

Also, if you have a new SSD and it starts to heat up, you should definitely contact your seller and try to claim a warranty!
