Best M.2 Heatsink for Samsung 990 Pro
The Samsung 990 Pro is an absolute beast for 4K video editing and high-resolution batch processing, but its blistering speeds come with a significant thermal trade-off. If you’ve ever watched your export speeds crawl during a long render, you’ve likely hit thermal throttling. After testing several cooling solutions in my own editing rig, I’ve found that the Be Quiet! MC1 Pro offers the perfect balance of thermal mass and slim design to keep your workflow fluid and fast.

Best Heatsinks for Samsung 990 Pro: Detailed Reviews
Be Quiet! MC1 Pro View on Amazon View on B&H
When you’re pushing the 990 Pro during a heavy Lightroom import or DaVinci Resolve export, you need more than just a slab of metal. The Be Quiet! MC1 Pro distinguishes itself with a built-in heat pipe that actively whisks heat away from the controller—the hottest part of the drive. I’ve found this to be the most reliable “set it and forget it” solution. It features a sleek, low-profile black finish that looks professional and fits easily under most large CPU air coolers. While it’s slightly more expensive than basic aluminum blocks, the inclusion of a dual-sided cooling design ensures the NAND flash on the back stays just as cool as the controller on the front. It’s a precision tool for a high-performance drive, though you should ensure your motherboard has the clearance for its 14mm height.

Thermalright HR-09 Pro View on Amazon View on B&H
If you have the vertical space in your case, the Thermalright HR-09 Pro is essentially a miniature CPU cooler for your SSD. It uses a high-density fin stack and a thick heat pipe that offers performance usually reserved for much more expensive active coolers. In my testing, this dropped the 990 Pro’s peak temperatures by nearly 20 degrees Celsius compared to a bare drive. It’s an incredible value proposition for enthusiasts who prioritize performance over aesthetics. However, you must be careful with compatibility; this thing is tall. If you’re using a large air cooler like a Noctua NH-D15, this heatsink will likely collide with it. For those with AIO liquid coolers or plenty of open space around the M.2 slot, there is simply no better cooling-per-dollar option on the market today.

MHQJRH M.2 Heatsink View on Amazon View on B&H
You don’t always need a liquid-cooled or heat-piped monster to keep your Samsung 990 Pro happy. The MHQJRH M.2 Heatsink is a straightforward, reliable aluminum heatsink that uses a sandwich design to cool both the top and bottom of the drive. For the price of a couple of lattes, you get a significant thermal upgrade over the stock Samsung sticker. It uses sturdy screws rather than rubber bands to secure the drive, which I find much more reassuring for long-term builds. While it won’t keep up with the Be Quiet! MC1 Pro during multi-hour video encodes, it’s more than sufficient for gaming or general office work. It’s also incredibly thin, making it compatible with almost any motherboard and GPU configuration you can imagine. It’s a “no-frills” choice that simply gets the job done.

ElecGear M11 View on Amazon View on B&H
For the user who refuses to compromise, the ElecGear M11 is the nuclear option. This isn’t just a heatsink; it’s an active cooling system featuring a 30mm PWM fan and a 6mm heat pipe. If you are regularly transferring terabytes of RAW video footage or running heavy database workloads, the 990 Pro can generate an immense amount of heat that passive sinks struggle to dissipate over time. The M11 ensures that fresh air is constantly moving across the thermal fins. I was pleasantly surprised by how quiet the fan is under normal loads, though you will hear a slight hum at full speed. It requires a 4-pin fan header on your motherboard, so make sure you have a spare. It’s overkill for most, but for “mission-critical” speed, it’s the king of the mountain.

SilverStone TP04 View on Amazon View on B&H
The SilverStone TP04 is a beautifully engineered piece of hardware that focuses on physical security and ease of installation. Instead of tiny screws that are easy to lose, it uses stainless steel clips to provide uniform pressure across the Samsung 990 Pro. This is vital because uneven pressure can lead to air gaps and poor thermal transfer. I’ve found it particularly useful in Small Form Factor (SFF) builds where space is at a premium but high-speed storage is still required. The finned aluminum top is efficient enough for most gaming and creative tasks. While it lacks the heat pipes of the premium models, its build quality is second to none. It’s a great middle-ground option for someone who wants better performance than a budget sink but doesn’t want the bulk of a “tower-style” cooler.

Frequently Asked Questions
Do I really need a heatsink for the 990 Pro?
If you are using the drive for gaming or everyday office tasks, the Samsung 990 Pro might survive without one, but it will likely hit its thermal limit and slow down during intense sessions. For video editors and photographers, a heatsink is mandatory. Sustained writes generate heat quickly, and once the controller reaches roughly 70°C, the firmware will throttle your speeds to prevent damage, turning your expensive Gen4 drive into a slow Gen3-speed performer.
Will an aftermarket heatsink void my Samsung warranty?
Generally, adding a heatsink does not void your warranty as long as you do not damage the drive during installation. You should leave the original Samsung labels on the drive, as they are actually thin copper heat spreaders themselves. Most modern heatsinks are designed to be placed directly over these labels. However, if you remove the label and damage the NAND chips or controller in the process, Samsung may deny your warranty claim.
Does the 990 Pro fit in a PS5 with these heatsinks?
The PS5 has very specific clearance requirements (11.25mm total height). The Be Quiet! MC1 Pro and the Thermalright HR-09 Pro are too tall for the PS5’s internal M.2 slot cover. If you are a console gamer, look for the SilverStone TP04 or the Sabrent PS5-specific heatsink. Always double-check the manufacturer’s height specifications before buying a heatsink for a console, as the space is much more restricted than a typical PC motherboard.
Is active cooling (fans) better than passive cooling?
Active cooling is objectively more effective at moving heat away from the drive, but it introduces two potential downsides: noise and mechanical failure. A small 30mm fan can develop a high-pitched whine over time. For 95% of users, a high-quality passive heatsink like the Be Quiet! MC1 Pro is more than enough. Only choose active cooling if you are working in a very hot environment or doing 24/7 server-style data transfers.
What are thermal pads and do I need to buy them separately?
Thermal pads are the “bridge” that transfers heat from the SSD chips to the metal heatsink. Almost every aftermarket heatsink, including the ones on this list, comes with thermal pads included in the box. You usually get a couple of different thicknesses to ensure a snug fit. While you can buy premium third-party pads from brands like Gelid or Thermal Grizzly, the ones included with the MC1 Pro or Thermalright are perfectly adequate for the 990 Pro.
Final Verdict
For the vast majority of professionals and enthusiasts, the Be Quiet! MC1 Pro is the smartest investment for a Samsung 990 Pro; it offers top-tier thermal management without compatibility headaches. If you’re on a tight budget, the MHQJRH will still offer a massive improvement over no cooling at all. However, if you’re a hardcore power user with space to spare, the Thermalright HR-09 Pro provides the absolute lowest temperatures we’ve seen on a passive air cooler.
