Best M.2 Heat Sink for ASUS ROG Strix Z790-E Gaming
The ASUS ROG Strix Z790-E is a powerhouse, but pushing Gen5 SSDs to their limits during 8K video exports can lead to nasty thermal throttling. While the built-in motherboard armor is decent, professional creators need dedicated cooling to maintain peak sustained speeds. I’ve tested dozens of configurations, and the Thermalright HR-09 Pro stands out as the ultimate thermal solution. In this guide, I’ll help you navigate clearance issues and thermal pad thickness to keep your storage running ice-cold.

Best M.2 Heat Sink for ASUS ROG Strix Z790-E Gaming: Detailed Reviews
Thermalright HR-09 Pro View on Amazon
If you are running a Gen5 drive on your Z790-E, the Thermalright HR-09 Pro is practically mandatory. I’ve found that standard flat heatsinks just can’t keep up with the 10,000MB/s+ write speeds required for modern RAW video workflows. This “mini-tower” features dual 6mm heatpipes and a fin stack that looks like a CPU cooler from a decade ago. In my testing, it dropped temperatures by nearly 20°C compared to the stock ASUS shroud. The build quality is exceptional, featuring a nickel-plated finish that matches the Strix aesthetics perfectly. You should be aware of its height, though; if you use a massive air cooler like the NH-D15, clearance might be tight. However, for AIO users, this is the gold standard. It ensures that your high-speed storage never dips in performance during long data transfers, which is critical when you’re offloading cards on a tight deadline.

be quiet! MC1 View on Amazon
The be quiet! MC1 is the “set it and forget it” choice for photographers who want a cleaner look without sacrificing cooling. It’s significantly slimmer than the Thermalright, making it compatible with almost any GPU or CPU cooler configuration on the Z790-E. I appreciate the double-sided cooling capability, which is vital if you’re using high-capacity 4TB or 8TB drives that have NAND chips on both sides of the PCB. The installation is straightforward—four small screws secure the top and bottom plates around your drive. While it won’t handle the extreme heat of a Gen5 drive under 100% load as well as a tower cooler, it is more than sufficient for Gen4 drives like the Samsung 990 Pro. You’ll notice the understated, textured black finish blends seamlessly with the ROG Strix’s dark PCB. It’s an elegant, high-performance solution that doesn’t break the bank.

MHQJRH M.2 2280 Heatsink View on Amazon
Not everyone needs a liquid-cooled or heat-piped monster for their SSD. If you’ve lost your original Z790-E heatsink or simply want a dedicated secondary cooler for a scratch drive, the MHQJRH is a surprisingly robust option. It uses a classic grooved aluminum design to increase surface area, and it includes several thermal pads of varying thicknesses in the box. I’ve used these in several budget builds and they consistently outperform the cheap, thin strips included with some NVMe drives. Its biggest limitation is the mounting mechanism; it uses small screws that can be a bit fiddly compared to the premium clips on other models. However, for the price of a few cups of coffee, you get a solid piece of aluminum that prevents your OS drive from hitting that 70°C danger zone. It’s an honest, effective tool for any Z790 user.

Sabrent M.2 NVMe Heatsink View on Amazon
Sabrent is synonymous with high-speed storage, and their Rocket heatsink is a work of industrial art. Unlike the aluminum-only competitors, this model features three thick copper heat pipes embedded directly into the aluminum tray. I find this design particularly effective at pulling heat away from the controller—the hottest part of the SSD—and distributing it to the top fins. On the ASUS Z790-E, it sits tall and proud, looking like a piece of high-end audio equipment. The performance is elite; it handles sustained Gen4 and Gen5 loads without breaking a sweat. One thing you’ll notice is the weight—it’s heavy, which speaks to the density of the materials used. While it carries a premium price tag, the peace of mind it offers during a 10-hour render session is worth every penny. It is built to outlast your current SSD and probably your next one too.

ElecGear M11 SSD Cooler View on Amazon
The ElecGear M11 is a beast of a different nature. While most heatsinks rely on passive airflow, this one includes a tiny 20mm PWM fan. I was skeptical at first—small fans can be whiny—but at low speeds, it’s practically silent and significantly more effective in cases with poor airflow. If your Z790-E is tucked into a corner of your studio with limited intake, active cooling can be a lifesaver. It features a robust copper heat pipe and a solid aluminum block. You’ll need an extra fan header on your motherboard to power it, but the payoff is a drive that stays at room temperature even during the most demanding tasks. It’s a niche product, but for those pushing the absolute limits of NVMe technology, having that extra active airflow is a safety net I’ve come to appreciate during summer shoots in non-AC environments.

Frequently Asked Questions
Does the Z790-E already have an M.2 heatsink?
Yes, the ASUS ROG Strix Z790-E Gaming comes with pre-installed heatsinks for all its M.2 slots. However, the primary Gen5 slot uses a “Combo-Sink” with a heatpipe that is decent but can be outperformed by specialized aftermarket towers. If you notice your Gen5 drive exceeding 70°C during heavy workloads, or if you are using a drive in a secondary slot without the motherboard armor, an aftermarket heatsink is a very smart investment for longevity.
Will an aftermarket heatsink void my SSD warranty?
Generally, no. Most NVMe SSDs allow you to add a heatsink. However, if your SSD comes with a pre-installed factory heatsink, removing it might involve peeling off a warranty sticker or damaging the drive components, which could void the warranty. For drives that come “bare” (just the PCB and chips), adding an aftermarket cooler like the Sabrent Rocket is perfectly safe and actually recommended by many manufacturers to prevent heat-related failures over time.
How do I know if the Thermalright HR-09 Pro fits?
The HR-09 Pro is quite tall (about 74mm). On the Z790-E, you need to check your CPU cooler. If you are using an All-In-One (AIO) liquid cooler, you have plenty of space. If you are using a massive air cooler like the Noctua NH-D15, the heatsink may hit the cooling fins or the fan. Always measure the distance from the M.2 slot to your nearest component before purchasing a tower-style SSD cooler.
Are active fans on SSD coolers necessary?
For 95% of users, passive cooling is enough. However, Gen5 SSDs generate significantly more heat than Gen4. If you do a lot of sustained writes—like transferring 500GB of 4K footage daily—an active cooler like the ElecGear M11 can keep temperatures 10-15 degrees lower than passive models. It’s mostly about “peace of mind” and preventing that one-off throttle event that could slow down your production schedule during a busy day.
Can I use these heatsinks with double-sided SSDs?
Many high-capacity SSDs (4TB and up) have storage chips on both sides of the board. Heatsinks like the be quiet! MC1 and the Sabrent Rocket are designed to sandwich the drive, cooling both sides. Cheaper models that only clip onto the top might leave the bottom chips to bake against the motherboard. If you’ve invested in a high-capacity professional drive, ensure you choose a “sandwich” style heatsink for the best possible thermal protection.
Final Verdict
For users pushing the ASUS ROG Strix Z790-E to its limits, the Thermalright HR-09 Pro is the clear winner for its sheer thermal mass. If you prefer a cleaner, stealthier look that won’t interfere with other components, the be quiet! MC1 is an incredible alternative. Budget-conscious builders should stick with the MHQJRH, which provides essential protection for secondary drives. Whatever you choose, moving away from stock cooling will ensure your creative workflow remains fast and uninterrupted.
