Best CPU Cooler for ASUS ROG Strix Z790-E
Building around the ASUS ROG Strix Z790-E requires a thermal solution that can tame Intel’s power-hungry 14th Gen chips without flinching. This motherboard is a beast, but its massive VRM heatsinks can make some air coolers a tight squeeze. After testing dozens of configurations, I’ve found that the ROG Ryujin III 360 stands out for its seamless ecosystem integration. Whether you’re chasing overclocking records or silent operation, the right cooler prevents thermal throttling and protects your high-end investment.

Best CPU Cooler for ASUS ROG Strix Z790-E: Detailed Reviews
ASUS ROG Ryujin III 360 ARGB View on Amazon
If you are already investing in the ROG Strix Z790-E, the Ryujin III 360 is the most logical companion. It features an Asetek 8th Gen pump that I’ve found to be incredibly quiet even under heavy synthetic loads. What really sets this apart for the Z790-E is the integrated fan within the pump block; it provides direct airflow to the motherboard’s VRMs, which is crucial when you’re pushing a 14900K to its limits. The 3.5-inch LCD screen is not just for show—I use it to monitor live clock speeds and temps via Armoury Crate. The magnetic daisy-chainable fans make cable management a dream, keeping your build looking as clean as it performs. The only real downside is the premium price tag, but for a flagship ASUS build, the synergy is simply unmatched.

DeepCool LS720 SE View on Amazon
The DeepCool LS720 SE is a revelation for builders who want 360mm AIO performance without the “ROG Tax.” In my testing, this cooler holds its own against units nearly twice its price. It utilizes DeepCool’s 4th-generation water pump which improves flow and efficiency, effectively managing the high TDP of the Z790-E’s supported CPUs. I particularly love the “infinity mirror” design on the pump cap—it looks sophisticated sitting next to the Strix’s RGB logo. The Anti-Leak technology provides that extra peace of mind we all crave when putting liquid near expensive components. While the fans can get a bit audible at 100% RPM, the cooling potential is massive. It’s the perfect middle ground for someone who wants a high-end look and top-tier thermals while keeping some budget left over for faster DDR5 RAM.

Thermalright Peerless Assassin 120 SE View on Amazon
It feels almost criminal how well the Thermalright Peerless Assassin 120 SE performs for its price. If you aren’t a fan of liquid cooling, this is the air cooler I recommend for the Z790-E. Despite its low cost, it features a robust dual-tower design with six heatpipes that can comfortably handle an i7-13700K or 14700K at stock settings. You’ll notice that it is surprisingly compact compared to some other giants, which helps with clearance around the Z790-E’s chunky VRM area. However, be mindful of your RAM height; you might need to slightly offset the front fan if you’re using tall RGB sticks. It doesn’t have the “wow” factor of an LCD screen, but it’s a workhorse that consistently punches above its weight. It’s an honest, effective solution for those who want to spend their money on performance rather than aesthetics.

Corsair iCUE H150i Elite LCD XT View on Amazon
The Corsair H150i Elite LCD XT is for the user who wants absolute control over their system’s aesthetic. The 2.1-inch IPS screen is vibrant, and the iCUE software—while heavy—offers the most granular control over fan curves and lighting I’ve ever used. It pairs beautifully with the ROG Z790-E as both represent the pinnacle of consumer PC tech. The AF RGB Elite fans included here are some of Corsair’s best, using AirGuide technology to concentrate airflow through the radiator. Performance-wise, it’s a beast, easily keeping a 14th Gen i9 under 85°C during intensive 4K video rendering. The “XT” revision also features an extended tubing length, which is a godsend for larger cases where the Z790-E usually lives. It’s an expensive choice, but the build quality and software polish justify the investment for professionals and enthusiasts alike.

Noctua NH-D15 chromax.black View on Amazon
For those who find the idea of liquid cooling terrifying, the Noctua NH-D15 chromax.black is the gold standard. It is a massive cooler, but I’ve confirmed it fits the ROG Z790-E with its recessed lower fins specifically designed for motherboard compatibility. The performance is legendary—it rivals many 240mm AIOs while remaining significantly quieter. I love the all-black aesthetic, which blends perfectly with the Z790-E’s dark PCB and heatsinks. There are no pumps to fail and no leaks to worry about, making it the “buy it once” choice. Just be aware that this cooler is huge; you’ll need a case with at least 165mm of CPU cooler clearance. If you value silence and peace of mind over flashy lights, this Austrian masterpiece is still the one to beat in the air-cooling world.

Frequently Asked Questions
Does the Z790-E come with a CPU cooler?
No, the ASUS ROG Strix Z790-E is a high-end enthusiast motherboard and does not include a stock cooler. Given the power requirements of the CPUs typically paired with this board, a stock cooler would be insufficient. You must purchase a high-quality aftermarket air or liquid cooler separately to ensure your system operates safely and maintains its performance during heavy workloads or gaming sessions.
Will a 240mm AIO be enough for an i9-14900K on this board?
While a 240mm AIO will fit and work, I generally don’t recommend it for an i9-14900K if you plan on doing anything more intensive than light gaming. These chips can pull over 300W under load, and a 240mm radiator will struggle to keep up, leading to thermal throttling. For the Z790-E, a 360mm AIO is the preferred choice for high-end i7 and i9 processors to ensure maximum boost clocks.
Do I need a separate mounting bracket for LGA 1700?
It depends on the age of the stock you receive. Most coolers manufactured in the last two years include the LGA 1700 bracket in the box. However, if you are repurposing an older cooler, you will likely need to order a specific mounting kit from the manufacturer. All the coolers listed in this guide are modern units that come ready for the Z790-E out of the box.
Can I use an air cooler with the ROG Strix Z790-E?
Absolutely! High-end air coolers like the Noctua NH-D15 or Thermalright Peerless Assassin are excellent choices. The main concern is RAM and VRM clearance. The Z790-E has very large heatsinks around the CPU socket, so you need to ensure the air cooler’s heatpipes and fins are designed to clear those obstacles. Both air coolers I recommended were selected specifically because they fit this board’s layout.
How do I control the RGB on my cooler via the motherboard?
For most coolers, you will connect the ARGB cable to one of the 3-pin 5V headers on the Z790-E. You can then use ASUS Armoury Crate (Aura Sync) to coordinate the lighting. If you choose an ROG cooler like the Ryujin, the integration is even deeper. Corsair coolers, however, use their own iCUE software, which can sometimes conflict with Aura Sync if not configured correctly.
Final Verdict
For the ultimate ASUS ROG Strix Z790-E experience, the Ryujin III 360 is my top recommendation—its VRM fan alone makes it worth the premium. If you’re building a high-end gaming rig but want to save some cash, the DeepCool LS720 SE offers nearly identical thermal performance for less. Finally, for those on a strict budget or who prefer the simplicity of air cooling, the Thermalright Peerless Assassin remains the undisputed king of value.
