Best M.2 SSD Heatsink for ASUS Prime Z790-P
The ASUS Prime Z790-P is a fantastic foundation for a high-performance workstation, but there’s a catch: only one of its M.2 slots comes with a pre-installed heatsink. If you’re a photographer or videographer like me, pushing high-speed Gen4 NVMe drives during 8K exports, you’ll quickly hit thermal throttling. To keep your data flowing and your drives healthy, an aftermarket cooler is essential. I’ve tested several options, and the Thermalright HR-09 Pro stands out as the ultimate thermal beast for this specific motherboard layout.

Best M.2 SSD Heatsink for ASUS Prime Z790-P: Detailed Reviews
Thermalright HR-09 Pro View on Amazon
If you are serious about maintaining peak read/write speeds during massive file transfers, the Thermalright HR-09 Pro is unrivaled. This isn’t just a slab of aluminum; it’s a full-scale tower cooler for your SSD. It features a 6mm heatpipe and a dense fin stack that leverages your case’s airflow beautifully. In my experience, it can drop temperatures on a Samsung 990 Pro by nearly 20°C compared to a bare drive. The ASUS Prime Z790-P has plenty of room around the lower M.2 slots for this height, though you’ll want to check clearance if you’re using a massive air cooler for your CPU. The build quality is exceptional, utilizing a solid backplate that ensures even pressure across the thermal pads. It’s slightly overkill for basic storage, but for a primary editing drive, it is absolute peace of mind.

Sabrent M.2 NVMe Heatsink View on Amazon
Sabrent has mastered the balance between form and function with this heatsink. It’s a low-profile aluminum design that fits perfectly into the Z790-P’s secondary and tertiary M.2 slots without interfering with your GPU. What I love about this model is the “sandwich” design; it wraps around the drive entirely, which is vital for double-sided SSDs where NAND chips are on both the top and bottom of the PCB. The thermal performance is solid, keeping most Gen4 drives well under 60°C during sustained use. It doesn’t have the “extreme” look of the Thermalright, making it a better choice for users who prefer the clean, professional aesthetic of the Prime series motherboard. My only gripe is the thermal pads are quite sticky, so be careful if you ever need to swap the drive out—slow and steady wins the race there!

MHQJRH M.2 2280 Heatsink View on Amazon
You don’t always need a fancy brand name to get the job done. This MHQJRH heatsink is a staple in the PC building community for a reason: it’s cheap and it works. It uses a simple but effective grooved aluminum top and a stainless steel tray. For the price of a fancy coffee, you get a significant upgrade over a bare drive. I’ve installed dozens of these on budget-conscious builds, and they consistently prevent the thermal throttling that plagues the Z790-P’s uncooled slots. It’s incredibly slim, meaning it will fit under virtually any GPU, even in the slot directly beneath the PCIe x16 lane. It does feel a bit “no-frills,” and the included thermal pads are average, but you’ll notice a massive difference in stability during long Lightroom imports. It’s the smart choice for a secondary game drive or scratch disk.

be quiet! MC1 Pro View on Amazon
The be quiet! MC1 Pro is for the user who wants professional-grade engineering without the “gamer” aesthetic. It features an integrated heatpipe, which is rare for a heatsink this slim. This allows it to move heat away from the controller much faster than solid blocks of metal. In a professional setting, where you might be rendering video for hours, this speed of heat dissipation is critical. It’s finished in a beautiful brushed black anodized aluminum that looks stunning against the black and silver accents of the ASUS Prime Z790-P. Installation is straightforward with high-quality screws rather than clips, giving it a very secure feel. While it’s more expensive than the Sabrent, the “Pro” version’s heatpipe makes it worth the premium for those using high-end Gen4 drives like the WD Black SN850X. It’s silent, efficient, and exceptionally well-made.

EZDIY-FAB M.2 RGB Heatsink View on Amazon
The ASUS Prime Z790-P has a somewhat understated design, and if you want to add a splash of color while keeping your drives cool, the EZDIY-FAB RGB is a fantastic addition. It connects directly to your motherboard’s ARGB headers, allowing you to sync it perfectly with ASUS Aura Sync. Beyond the lights, it’s actually a very capable cooler. The aluminum body is substantial enough to handle mid-range Gen4 drives without issue. I find this particularly useful for “show” builds where the M.2 slots are visible through a tempered glass side panel. You should be aware that it adds a bit of cable clutter, as you’ll have to route the thin ARGB wire to a header. However, if you’re already running an RGB setup, this is a no-brainer. It effectively combines aesthetics with a 10-15°C temperature drop, which is a win-win in my book.

Frequently Asked Questions
Do I really need a heatsink for the Z790-P?
While the top slot has one, the other M.2 slots are bare. If you’re using a PCIe 4.0 drive for tasks like video editing, gaming, or large file transfers, the drive will hit its thermal limit (usually 70°C+) and slow down significantly to protect itself. Adding a $15 heatsink prevents this “throttling” and ensures you get the speeds you actually paid for, while also extending the drive’s lifespan.
Will a tall heatsink like the HR-09 Pro fit under my GPU?
Generally, no. Tower-style heatsinks are too tall to fit directly beneath a dedicated graphics card. On the ASUS Prime Z790-P, you should use the HR-09 Pro in the bottom-most slot (M2_3) if you have a large GPU. For the middle slot (M2_2), which sits right under the PCIe x16 lane, you should stick to low-profile options like the Sabrent or be quiet! MC1 Pro.
Can I use these with the pre-installed ASUS heatsink?
No, these are designed to replace or be used instead of the factory heatsink. Since the ASUS Prime Z790-P only provides a heatsink for the top slot, you should leave that one as is and use these aftermarket coolers for your second or third NVMe drives. If you really want to replace the ASUS one for better performance, you can, but it’s usually not necessary for the top slot.
Are the included thermal pads good enough?
Most included pads are decent (usually 3-6 W/mK), but they aren’t top-tier. For most users, they work perfectly fine. If you are an extreme power user, you could swap them for Thermal Grizzly Minus Pad 8, but for a standard Z790-P build, the pads that come with the Thermalright or be quiet! models are high-quality enough that you won’t see a meaningful difference by switching them.
Does installing a heatsink void my SSD warranty?
In most cases, no. However, you should never remove the manufacturer’s sticker on the SSD itself (the one with the serial number), as that often contains a thin layer of copper or foil that acts as a heat spreader anyway. Simply place the thermal pad and heatsink directly over that sticker. Removing the sticker is what usually triggers a warranty void, not the act of adding a cooler.
Final Verdict
For the ASUS Prime Z790-P, I highly recommend the Thermalright HR-09 Pro if you have the space; it’s a game-changer for content creators. If you need something that fits under a beefy RTX 40-series GPU, go with the be quiet! MC1 Pro or the Sabrent. Both offer excellent thermal management without the bulk. Regardless of which you choose, adding any of these is a massive upgrade over leaving your high-speed drives bare and prone to overheating.
