Best CPU Cooler for ASUS ROG Strix Z790-E Gaming WiFi
Taming the heat of a high-end Intel 13th or 14th Gen processor on an ASUS ROG Strix Z790-E Gaming WiFi is no small feat. With those beefy VRMs and the board’s massive power delivery, you need a thermal solution that matches its premium pedigree. I’ve tested dozens of configurations, and while the ASUS ROG Ryujin III is the ultimate ecosystem choice, finding the right balance of noise and thermals is key. Here are my top expert-vetted picks for your build.

Best CPU Coolers for ASUS ROG Strix Z790-E: Detailed Reviews
ASUS ROG Ryujin III 360 ARGB View on Amazon
If you’re running an i9-14900K on your Strix Z790-E, the ASUS ROG Ryujin III 360 is the gold standard. I find the integration here exceptional; the built-in VRM fan actually helps lower the temperatures of the Z790-E’s already impressive power stages during heavy overclocking. It features an Asetek 8th Gen pump which is noticeably quieter than its predecessor while moving more coolant. The 3.5-inch LCD screen isn’t just for show—you can monitor real-time clock speeds or temps directly through Armoury Crate. You’ll notice the magnetic daisy-chainable fans make cable management a breeze, which is a blessing given the Z790-E’s crowded header layout. The only real drawback is the “ROG Tax”—it is significantly more expensive than competitors, but for a unified aesthetic and top-tier performance, it’s hard to beat.

Arctic Liquid Freezer III 360 View on Amazon
The Arctic Liquid Freezer III 360 is widely regarded as the “giant killer” in the AIO world. What makes it special for the Z790-E is its massive 38mm thick radiator—most competitors use 27mm or 30mm. This extra surface area provides incredible thermal headroom for those 250W+ power bursts Intel chips are known for. I’ve found the proprietary VRM fan on the pump block to be surprisingly effective, though it’s a bit of a tight fit near the Z790-E’s tall top heatsinks. The installation is much improved over the Version II, utilizing a contact frame for better pressure on LGA 1700 sockets. It doesn’t have the flashy LCD screens of the Ryujin, but in terms of raw cooling per dollar, nothing else comes close. Be aware that the thicker radiator might require a larger case to clear the top of the motherboard.

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’re building a gaming-focused rig on the Z790-E and aren’t planning on heavy multi-core rendering, this air cooler is more than enough. It features a dual-tower design with six heatpipes that punched way above its weight class in my testing. You’ll notice it’s surprisingly compact for a dual-tower, but you should still check your RAM height; the front fan might need to be shifted up slightly if you’re using tall RGB sticks. While it won’t keep an i9 at 5.8GHz indefinitely under a Cinebench load, it handles gaming loads with ease and quietness. It’s an honest, no-nonsense cooler that proves you don’t need to spend $200 to get decent thermals on the LGA 1700 platform.

Corsair iCUE H150i Elite LCD XT View on Amazon
For those who value aesthetics as much as performance, the Corsair H150i Elite LCD XT is a masterpiece. Its 2.1-inch IPS LCD is incredibly crisp, and the iCUE ecosystem allows for some of the most sophisticated lighting synchronization available today. Performance-wise, it utilizes the AF RGB Elite fans which provide high static pressure while remaining remarkably quiet. In my experience, the iCUE software provides a much more granular level of control over pump speeds and fan curves than ASUS’s Armoury Crate. However, the installation involves a Commander Core controller, which adds significant cable clutter behind your motherboard tray. It’s a premium experience from start to finish, perfect for showcasing the Z790-E in a tempered glass case, provided you have the patience for the extra wiring.

Noctua NH-D15 chromax.black View on Amazon
The Noctua NH-D15 is the “old faithful” of the PC world. If you’re wary of water cooling or just want a “set it and forget it” solution for your Z790-E build, this is it. The chromax.black version finally ditches the beige-and-brown for a sleek look that matches the Strix motherboard perfectly. While it’s huge, the Z790-E’s VRM heatsinks are designed with enough clearance for high-end air towers like this. Performance is legendary; it competes with many 240mm and even some 280mm AIOs while being virtually silent at idle. The main downside is RAM clearance—you’ll likely need to use low-profile RAM or raise the front fan, which might make the cooler too tall for some mid-tower cases. But for pure peace of mind and longevity, Noctua remains king.

Frequently Asked Questions
Does the Z790-E require a specific mounting bracket?
Yes, you need an LGA 1700 mounting kit. Most modern coolers released after 2022 include this in the box. If you’re repurposing an older cooler, you’ll likely need to order a separate bracket from the manufacturer. The Z790-E has dual mounting holes for LGA 1200 and LGA 1700, but using the native LGA 1700 hardware is always recommended for the best mounting pressure.
Is a 240mm AIO enough for an i9-14900K?
Technically, it will work, but you’ll see thermal throttling during heavy multi-core tasks. For an i9 on a high-end board like the Z790-E, I strongly recommend at least a 360mm radiator. If you’re only gaming, a 280mm might suffice, but you’ll lose out on the top-end performance that the Z790-E’s power delivery system is designed to provide.
Will the Arctic Liquid Freezer III fit in my case?
The Arctic LF III has a 38mm thick radiator plus 25mm fans, totaling 63mm. This is thicker than the standard 52-55mm combo. Check your case specs for “top radiator clearance.” In many mid-towers, a thick radiator can hit the Z790-E’s top VRM heatsink or the RAM. Ensure you have enough offset or vertical space before buying.
Can I use an air cooler for overclocking on this board?
You can, but air coolers have a lower “thermal ceiling.” A top-tier air cooler like the Noctua NH-D15 can handle moderate overclocks on an i7, but for pushing an i9 to its limits, water cooling is much more effective at whisking heat away quickly. Air coolers are better for those who value long-term reliability over absolute maximum clock speeds.
Does the Z790-E have enough headers for these AIOs?
Absolutely. The ROG Strix Z790-E is loaded with fan headers, including a dedicated AIO_PUMP header and multiple ARGB Gen 2 headers. Most high-end coolers like the Ryujin III or Corsair H150i will use internal USB 2.0 headers for data control, and the Z790-E provides two of those, which is usually plenty for most builds.
Final Verdict
For the ultimate ASUS ROG Strix Z790-E experience, the Ryujin III 360 is the clear winner, offering integrated VRM cooling that complements the board perfectly. If you’re more focused on performance than branding, the Arctic Liquid Freezer III is a thermal beast that saves you a significant chunk of change. Budget-conscious gamers or those who prefer air cooling should look no further than the Thermalright Peerless Assassin.
