Modern NVMe SSDs are insanely fast. They can move tens of gigabytes of data in minutes, but all that speed comes at a cost: heat. Adding a heatsink is an excellent way to protect a fast NVMe from overheating, but you don’t need to go overboard by getting a model with a tiny cooling fan.
NVMe heatsinks are essential for an SSD’s lifespan
Your NVMe will get fried without one
Before we dive into active vs. passive NVMe cooling (fan vs. no fan), let’s first explain why these drives even need chunks of metal in the first place.
Modern PCIe Gen 4 and especially Gen 5 NVMes can get extremely hot during lengthy file transfers. Without a heatsink, temperatures can easily climb above 85°C, which accelerates wear and tear on the NVMe controller and even the NAND flash over prolonged periods.
To combat this heat buildup, an NVMe throttles performance when it recognizes it’s at a critical temperature, but even then, it stays very hot until the transfer finishes, which significantly reduces its lifespan.
Even if you don’t often move huge files, an NVMe can still overheat and fail from regular use if your PC lacks proper airflow around the drive. Since NVMes are usually located between the CPU and GPU, they sit in one of the hottest spots in a system.
Fortunately, most modern motherboards include at least one NVMe heatsink, which is usually all you need for a single drive. If your motherboard doesn’t have one, or if you have multiple drives, a passive NVMe heatsink with a bottom bracket, like the Arctic M2 Pro, is an inexpensive and effective solution.
Active NVMe coolers are overkill in a consumer PC
It’s too much of a good thing
Passive NVMe heatsinks do a pretty decent job of soaking up heat from an NVMe, but they still rely on your PC’s airflow to actually dissipate it. Adding a tiny fan directly to the heatsink can remove that heat much more effectively.
That’s essentially the problem NVMe heatsinks with fans—like the Thermalright HR10 2280 Pro and Thermaltake MS-1—are trying to solve.
As expected, these active heatsinks do a great job cooling NVMes. Tom’s Hardware tested several NVMe heatsinks using a PCIe Gen 5 drive, and the Thermalright HR10 2280 Pro was near the top, along with a few other active solutions. It maxed out at 50°C in the torture test, which is extremely harsh and not representative of real-world usage.
However, most of the time, your NVMe won’t need anywhere near this level of cooling, even during heavy file transfers. If you look closer at Tom’s Hardware’s test, several passive heatsinks, like the ID-Cooling Zero M15 (which is available on AliExpress for around $10), also held up really well, topping out at 63°C. That’s comfortably below the 75°C threshold where Gen 5 drives start to throttle.
The main problem with these tiny fans is that they can get extremely loud, often producing a quiet but annoying constant whirring that can bother you while browsing the web or working.
Another downside many chunky NVMe heatsinks face is compatibility. They might not fit under wider air CPU coolers, and you’ll often have to sacrifice a fan header on your motherboard or fan hub to power the fan, which can complicate your build.
Finally, fans are moving parts, and because they’re so small, dust buildup can cause them to fail prematurely—leaving you with a passive solution that you probably paid extra for.
Stop running your NVMe ‘naked’: Why modern SSDs need a heatsink
Your SSD is hotter than it should be, and it’s only going to get worse
NVMe enclosures are a whole other story
Enclosures are a special case
Although fans don’t have much of a place on NVMe heatsinks inside a desktop PC, it’s a whole different story with NVMe enclosures.
Passive NVMe heatsinks can dissipate heat effectively because they benefit from airflow generated by the rest of your system, but an enclosure can get extremely hot if it only has the metal case to rely on for heat dissipation.
Plus, if you own an NVMe in an enclosure, there’s a good chance you use it primarily for file transfers. Given how expensive these drives can be, you probably use yours often and want to maximize both its lifespan and transfer speeds.
For those reasons, a high-quality enclosure with a fan can make more sense than a fanless solution, provided you can shoulder the higher cost.
Only get an active NVMe heatsink if you absolutely need it
Workstation owners rejoice
Realistically speaking, most PC owners don’t need to worry about NVMe temperatures once a passive heatsink is installed. Unless you like transferring huge files for fun, your NVMe will rarely reach dangerous operating temperatures, which makes a heatsink with a fan complete overkill.
Honestly, the only time you should consider one of these is if you run a workstation and your workflow is heavy on NVMe storage, such as video or image editing. They can also make for a solid cooling solution if you’re using an M.2 AI inference accelerator.
