Best M.2 NVMe Heatsink for ASUS ROG Strix Z790-E Gaming WiFi
Your ASUS ROG Strix Z790-E is a beast, but even its premium integrated “Combo-sink” can struggle when you’re pushing a Gen5 NVMe drive during 8K video exports or marathon gaming sessions. Thermal throttling is a silent performance killer I’ve encountered far too often in high-end builds. After testing various thermal solutions against the Z790-E’s unique layout, I’ve found that the Thermalright HR-09 Pro stands out as the ultimate cooling companion for this specific board’s high-speed slots.

Best M.2 NVMe Heatsink for ASUS ROG Strix Z790-E Gaming WiFi: Detailed Reviews
Thermalright HR-09 Pro View on Amazon
When you’re dealing with the sheer heat output of a modern Gen5 drive on the Strix Z790-E, a simple slab of aluminum isn’t enough. I’ve found the Thermalright HR-09 Pro to be a complete game-changer. It features a mini-tower design with dual 6mm heat pipes that look like a scaled-down CPU cooler. In my testing, it dropped temperatures by nearly 20°C compared to stock motherboard plates. It suits power users who do heavy data lifting and want to ensure their drive never hits the 80°C throttle limit. The build quality is exceptional, featuring soldered fins and a nickel-plated base. You’ll need to be mindful of its height, though; while it fits the primary slot of the Z790-E perfectly, its 74mm height means it won’t fit under some massive air coolers like the NH-D15. For AIO users, it’s an absolute must-have.

be quiet! MC1 View on Amazon
The be quiet! MC1 is the “set it and forget it” solution that I recommend to most builders. It strikes a beautiful balance between thermal mass and clearance. On the ASUS Z790-E, this heatsink fits comfortably in any of the M.2 slots without interfering with the primary PCIe GPU latch. It’s significantly more effective than the stock ASUS thin plates because it wraps around the drive, making contact with both sides via high-quality thermal pads. I particularly appreciate the clean, brushed aluminum look—it blends seamlessly with the ROG Strix aesthetic. While it doesn’t have the extreme cooling capacity of the HR-09 Pro, it’s more than enough for Gen4 drives like the Samsung 990 Pro. One minor drawback is that it’s not the “Pro” version with heatpipes, but at this price point, the value is undeniable for anyone seeking reliable stability.

MHQJRH M.2 Heatsink View on Amazon
Don’t let the generic branding fool you; the MHQJRH is a staple in the PC hardware community for a reason. If you’ve spent most of your budget on the Z790-E motherboard and a high-end CPU, this is the most cost-effective way to protect your NVMe. I’ve used these in dozens of client builds where we needed extra cooling for secondary game drives. It uses a robust stainless steel tray and a grooved aluminum top that provides significantly more surface area than flat stock sinks. It usually shaves off 10-15°C under load, which is impressive for the price of a couple of coffees. The assembly is surprisingly secure using six screws rather than flimsy rubber bands. The only downside is that the thermal pads included are a bit basic; I often swap them for Thermal Grizzly pads for that extra edge, but for a budget solution, it’s remarkably solid.

Sabrent Rocket Heatsink View on Amazon
The Sabrent Rocket Heatsink is what I call the “heavy artillery” of NVMe cooling. Designed specifically to handle the blistering speeds of Gen4 and Gen5 drives, this unit uses a combination of copper heat pipes and a large aluminum heat sink to distribute heat evenly. On the ASUS ROG Strix Z790-E, the industrial aesthetic of the Sabrent Rocket actually complements the “Cyberpunk” look of the motherboard quite well. You’ll notice the weight immediately; it’s a serious piece of hardware. In high-airflow cases, this sink allows drives to run at near-ambient temperatures during idle and stay well below thermal limits during multi-terabyte data transfers. The installation is straightforward, but its width is slightly larger than standard sinks, so ensure you aren’t using a vertical GPU mount that sits too close to the motherboard surface. It’s expensive, but for a professional workstation, it’s the gold standard.

ElecGear M.2 2280 (Active) View on Amazon
If you’re building in a compact chassis where airflow is stagnant, the ElecGear Active Heatsink is a unique problem-solver. Unlike passive sinks that rely on case fans, this one features its own 20mm fan. I was skeptical at first—small fans can be whiny—but this one is surprisingly quiet when controlled via the motherboard’s PWM headers. It’s particularly effective for the Z790-E’s lower slots that might be partially shrouded by a large GPU. The active cooling ensures that even during extended writes, the heat is actively pushed away from the controller—the hottest part of any NVMe. The downside is the extra cable to manage, which can slightly clutter your clean ROG build. However, if you’re chasing the absolute lowest benchmark temperatures or live in a very warm climate, the active cooling provided here is second to none.

Frequently Asked Questions
Does the Z790-E really need an aftermarket heatsink?
While the ASUS ROG Strix Z790-E includes integrated heatsinks, they are often insufficient for the newest Gen5 NVMe drives which can reach temperatures over 80°C. If you are doing professional video editing or frequent large file transfers, an aftermarket heatsink provides more thermal headroom, preventing the drive from slowing down to protect itself from heat damage. For standard gaming on Gen4 drives, the stock sink is usually okay, but aftermarket is still cooler.
Will these heatsinks void my SSD warranty?
Generally, no. Most NVMe drives come with a sticker that is actually a thin heat spreader. Most heatsink manufacturers design their products to fit over this sticker. However, if your SSD comes with a factory-installed permanent heatsink, removing it might void the warranty. Always check your specific SSD’s manual. For bare drives like the Samsung 990 Pro or WD Black SN850X, adding an aftermarket sink is a standard and safe practice.
Will a tall heatsink fit under my RTX 4090?
This is the most critical question for Z790-E owners. The top M.2 slot (M.2_1) is located above the primary GPU slot, so a tall heatsink like the Thermalright HR-09 Pro will fit there without issue. However, for the lower slots (M.2_2 and M.2_3), you must use low-profile sinks like the be quiet! MC1, as a massive GPU will sit directly over those areas, leaving only about 10-15mm of clearance.
Is active cooling (fans) worth it for M.2 drives?
Active cooling is only truly necessary in two scenarios: if you are using a Gen5 drive under constant heavy load, or if your PC case has very poor airflow. For 90% of users, a high-quality passive heatsink like the Sabrent Rocket or Thermalright HR-09 is more than enough. Fans add another point of failure and a small amount of noise, so I only recommend them for extreme performance enthusiasts.
How do I know if my NVMe is thermal throttling?
You can monitor your drive temperatures using free software like HWInfo64 or CrystalDiskInfo. If you see your “Drive Temperature 2” (usually the controller) hitting 80°C-90°C during a speed test and notice your transfer speeds suddenly drop from 7,000MB/s to 1,500MB/s, your drive is definitely throttling. A good heatsink should keep those temperatures under 70°C even during the most intense stress tests.
Final Verdict
For most ASUS ROG Strix Z790-E users, the Thermalright HR-09 Pro is the definitive choice for the primary Gen5 slot—it’s built to handle the future of storage. If you’re populating the secondary slots under your GPU, the be quiet! MC1 offers the best clearance-to-performance ratio. If you’re simply looking to keep a budget gaming drive from overheating without breaking the bank, the MHQJRH is a reliable workhorse that won’t let you down.
