Best M.2 SSD Heatsink for ASUS ROG Maximus Z790 Hero
Pushing an ASUS ROG Maximus Z790 Hero to its limits with 8K video exports or high-res batch processing requires storage that doesn’t throttle. While the Hero’s built-in armor is decent, Gen5 SSDs and high-performance Gen4 drives often need more thermal mass to stay stable. After testing various cooling solutions on my own editing rig, I’ve found that the Thermalright HR-09 Pro is the undisputed king for maintaining peak transfer speeds during grueling creative sessions.

Best M.2 SSD Heatsink for ASUS ROG Maximus Z790 Hero: Detailed Reviews
Thermalright HR-09 Pro View on Amazon
The Thermalright HR-09 Pro is essentially a miniature CPU cooler for your SSD. When I first installed this on my Z790 Hero’s primary Gen5 slot, the temperature drop was staggering—nearly 20°C cooler under sustained load compared to the stock motherboard shroud. It features a robust dual-heatpipe system and a finned aluminum tower that stands tall. While its height means it won’t fit under a massive GPU in the lower slots, it is perfect for that top M.2 slot. The build quality feels premium, matching the aesthetics of a high-end ROG board. If you are moving massive RAW photo libraries or scrubbing through 10-bit 4:2:2 video timelines, this is the insurance policy your data needs. Just be mindful of air cooler clearance if you aren’t using an AIO.

be quiet! MC1 View on Amazon
If the Thermalright is a monster, the be quiet! MC1 is a sleek, sophisticated tool. It’s designed for users who want better-than-stock cooling without the bulk. I love using these for the secondary M.2 slots on the Z790 Hero because they fit comfortably under most high-end graphics cards. The all-black finish is understated and doesn’t scream “gamer,” which I appreciate in a professional studio environment. It provides excellent pressure on the SSD chips thanks to its backplate design, ensuring even heat transfer. While it lacks the extreme cooling capacity of a heatpipe-based tower, it easily handles high-performance Gen4 drives like the Samsung 990 Pro. It’s a reliable, no-nonsense upgrade that looks like it belongs on a premium ASUS motherboard.

MHQJRH M.2 2280 Heatsink View on Amazon
Sometimes you don’t need a fancy brand name; you just need more surface area. The MHQJRH is a simple, effective aluminum heatsink that outperforms many stock motherboard solutions simply by being thicker. For a photographer who has added an extra “scratch disk” SSD to one of the Z790 Hero’s open slots and realized they lost the original ASUS screw or pad, this is the perfect replacement. It uses a clip-on mechanism that is surprisingly secure. While the thermal pads included are basic, they do the job for standard workloads. You won’t get the world-class performance of a Sabrent or Thermalright, but for the price of a couple of lattes, you’re getting a significant upgrade over a bare drive that might otherwise throttle during a Lightroom export.

Sabrent Rocket M.2 NVMe Heatsink View on Amazon
The Sabrent Rocket Heatsink is the “L-series lens” of the SSD world. It is a beautiful piece of engineering, utilizing thick copper heat pipes and a massive aluminum sink to pull heat away from your controller instantly. On the Z790 Hero, this heatsink looks absolutely stunning, complementing the board’s industrial aesthetic. It’s specifically designed to handle the localized “hot spots” that high-speed controllers generate. In my testing, it keeps even the most aggressive PCIe 4.0 drives within a very tight temperature window. The installation is a bit more involved, requiring you to sandwich the drive carefully, but the result is rock-solid stability. If you’re building a “no compromises” workstation for high-end content creation, this is the premium choice that matches the pedigree of your Maximus motherboard.

SilverStone TP04 View on Amazon
SilverStone has been in the cooling game forever, and the TP04 shows their experience. It’s a very well-balanced heatsink that focuses on ease of installation and thermal pad quality. One thing you’ll notice is the stainless steel clips—they provide much better tension than the rubber bands some cheap models use. This tension is critical for ensuring the thermal pad makes perfect contact with both the NAND flash and the controller. On the Z790 Hero, it’s a great middle-ground option for those who find the be quiet! too slim but the Sabrent too expensive. It’s particularly good at dissipating heat in cases with moderate airflow. It won’t win any beauty contests, but it’s a reliable workhorse that ensures your project files stay safe from heat-induced corruption.

Frequently Asked Questions
Does the Z790 Hero really need an aftermarket heatsink?
For most Gen4 drives, the built-in ASUS ROG armor is quite capable. However, if you are using a Gen5 SSD or a drive that runs notoriously hot like the WD Black SN850X under sustained 4K video editing loads, an aftermarket solution like the Thermalright HR-09 Pro provides significantly more surface area. This prevents thermal throttling, which can cut your transfer speeds in half just when you need them most during a big export.
Will these heatsinks fit under my graphics card?
It depends on the model. Low-profile options like the be quiet! MC1 or the SilverStone TP04 are specifically designed to fit in slots that sit behind a GPU. However, “tower” style coolers like the Thermalright HR-09 Pro will definitely interfere with a graphics card. On the Z790 Hero, I recommend using the massive tower coolers only in the top M.2 slot, which is usually situated above the primary PCIe slot.
Can I use a heatsink on a drive that already has one?
Most NVMe drives with factory-installed heatsinks (like some Samsung or WD models) are not designed to be disassembled. Removing the factory sink can void your warranty and potentially damage the NAND chips. If your drive came with a heatsink, stick with it! Only buy these aftermarket options for “bare” drives or if you are specifically looking to upgrade from a basic motherboard shroud to something more substantial.
Are the included thermal pads good enough?
The pads included with brands like Sabrent and be quiet! are generally high-quality. However, budget options like the MHQJRH use basic pads. If you are a power user, I often suggest buying a sheet of high-performance thermal padding (like Thermal Grizzly Minus Pad) to use with a budget heatsink. This “frankenstein” approach can give you premium performance at a lower total cost, ensuring your controller stays cool during long file transfers.
Is installation difficult on the Maximus Z790 Hero?
Not at all, but it requires patience. You’ll need to remove the motherboard’s existing M.2 armor first. Keep those screws safe! Once the bare slot is exposed, you simply sandwich your SSD between the new heatsink and its backplate. The trickiest part is ensuring the thermal pads are aligned perfectly with the controller chip, which is the hottest part of the drive. Most of these options use a simple screw or clip system.
Final Verdict
For the professional creator using an ASUS ROG Maximus Z790 Hero, the Thermalright HR-09 Pro is the best choice for the primary Gen5 slot to ensure zero throttling. If you need to cool secondary drives tucked under a GPU, the be quiet! MC1 offers a sleek, low-profile fit that doesn’t compromise on quality. Budget-conscious builders will find the MHQJRH more than capable for standard Gen4 storage needs.
