Best Thermal Paste for ASUS ROG Strix Z790-E
Pushing an Intel 14th Gen chip on the ASUS ROG Strix Z790-E is like shooting 8K RAW video on a high-end mirrorless—it generates immense heat that can throttle your performance if not managed correctly. Choosing the right thermal interface material is the most underrated upgrade for your rig. After testing dozens of compounds against the Z790-E’s demanding power delivery, I’ve found that Thermal Grizzly Kryonaut remains the undisputed gold standard for maintaining peak clock speeds during intensive workloads.

Best Thermal Paste for ASUS ROG Strix Z790-E: Detailed Reviews
Thermal Grizzly Kryonaut View on Amazon
In the world of high-performance computing, Thermal Grizzly Kryonaut is the equivalent of a fast f/1.2 prime lens—it offers clarity and performance where others blur. Designed specifically for demanding applications, its 12.5 W/mk thermal conductivity ensures that heat is whisked away from your i9-14900K instantly. I’ve personally used this on several Z790-E builds, and the consistency is remarkable. It doesn’t require a cure time, meaning you get peak performance the second you hit the power button. The spreadable consistency is perfect for the larger integrated heat spreaders (IHS) found on LGA 1700 CPUs. While it is pricier per gram than industrial-grade pastes, the 3-5 degree Celsius drop over standard compounds is vital when you’re pushing 5.7GHz+ frequencies. Just be aware that it can begin to dry out if exposed to temperatures consistently above 80°C for years, so an annual re-paste is recommended for the most meticulous enthusiasts.

Arctic MX-6 View on Amazon
The Arctic MX-6 is the “workhorse zoom lens” of thermal pastes. It might not have the exotic prestige of liquid metal, but it gets the job done reliably every single time. Arctic has improved the thermal resistance significantly over the legendary MX-4, making this a fantastic match for the ROG Strix Z790-E. What I love about MX-6 is its high viscosity; it’s thick enough to stay exactly where you put it, preventing the “pump-out” effect that plagues thinner pastes under thermal cycling. This makes it ideal for users who don’t want to open their case for the next five to eight years. It’s non-conductive and non-capacitive, so even if you’re a bit messy with the application around those delicate Z790 capacitors, your motherboard is perfectly safe. While it trails Kryonaut by a degree or two in extreme synthetic benchmarks, the price-to-performance ratio is simply unbeatable for a daily gaming machine.

Noctua NT-H1 View on Amazon
If you’ve ever used a Noctua fan, you know their commitment to engineering. The NT-H1 is their classic thermal compound, and it’s still one of the most user-friendly pastes on the market. For a Z790-E owner who might be intimidated by the “buttering” method of application, NT-H1 is a dream. You just put a dot in the middle, mount the cooler, and the pressure handles the rest perfectly. It has a very low dry-out rate and remains stable across a wide range of temperatures. While it’s technically “budget-friendly,” its performance is still top-tier, often beating out much more expensive boutique brands. It doesn’t quite reach the thermal conductivity peaks required for world-record overclocking, but for a standard gaming build or a workstation setup using an i7-13700K, it’s more than sufficient. I find its consistency to be just right—not too runny, not too stiff—making it the safest bet for beginners.

Kingpin Cooling KPx View on Amazon
When you move into the territory of extreme overclocking on the Z790-E, you need the Kingpin Cooling KPx. This paste is like the medium-format camera of the hardware world—it’s designed for those who demand the absolute maximum from their gear. Developed by Vince “Kingpin” Lucido, this compound is specifically engineered to avoid “cracking” or losing effectiveness at sub-zero temperatures, but it performs just as brilliantly on custom water loops or high-end AIOs. It has a blue tint and a very smooth, non-curing formula that makes it easy to apply even on large surfaces. In my testing, KPx provides some of the lowest delta temperatures I’ve seen on the 14th Gen platform. It is a premium product with a premium price tag, but if you’ve invested in a top-tier ROG motherboard and a 360mm radiator, skipping on the paste is a mistake. It’s the ultimate choice for squeezing every last MHz out of your silicon.

Gelid GC-Extreme View on Amazon
Gelid GC-Extreme is a veteran in the thermal paste arena, and for good reason. It’s incredibly thick, which might make it a bit of a challenge to apply compared to the Noctua NT-H1, but that density is exactly what makes it so effective. On a motherboard like the Z790-E, which can sometimes suffer from slight socket warping (common with LGA 1700), the GC-Extreme’s ability to fill microscopic gaps is a huge advantage. I often recommend this for users who are using large air coolers like the NH-D15, where mounting pressure is high. It doesn’t bleed or run, and its thermal performance remains remarkably consistent even after years of heavy gaming sessions. It’s like a vintage Leica lens—built like a tank and still producing world-class results despite newer competitors. If you take your time with a spreader to get an even coat, the GC-Extreme will reward you with rock-solid thermals.

Frequently Asked Questions
How often should I replace the paste on my Z790-E?
For high-performance systems like those built on the ROG Strix Z790-E, I recommend re-pasting every 18 to 24 months. Over time, thermal cycling causes the paste to dry out or “pump out” from the center of the die, leading to higher temperatures. If you notice your CPU hitting 90°C+ in tasks where it used to stay at 80°C, it is definitely time for a fresh application of Kryonaut or MX-6 to restore efficiency.
Should I use the pea-size or spread method?
Because the LGA 1700 CPUs used in the Z790-E are rectangular rather than square, the traditional pea-size method might not cover the corners effectively. I personally prefer the “X” method or using a small spatula to create a thin, even layer across the entire heat spreader. This ensures that every part of the silicon die underneath has a direct thermal path to your cooler, which is crucial for high-TDP Intel chips.
Is liquid metal safe to use on this motherboard?
Liquid metal, like Thermal Grizzly Conductonaut, offers the best performance but is electrically conductive. While the Z790-E is a robust board, I don’t recommend liquid metal for most users unless you are an expert. A single drip can short out your motherboard. Furthermore, liquid metal should only be used with nickel-plated copper coolers; it will chemically destroy aluminum heatsinks. For 99% of gamers, a high-end traditional paste like KPx is much safer.
Do these thermal pastes have an expiration date?
Most high-quality thermal pastes have a shelf life of about 2 to 3 years if kept in a cool, dark place with the cap tightly sealed. If you open an old syringe and find that the oil has separated from the gray compound, or if it has become crumbly and hard to extrude, do not use it. Using expired paste can lead to air pockets and poor thermal transfer, which defeats the purpose of buying a premium motherboard.
Will better thermal paste actually improve my FPS?
Directly, no; however, indirectly, yes. Modern Intel CPUs use “Thermal Velocity Boost,” which allows the chip to run at higher clock speeds as long as temperatures remain low (usually under 70°C). By using a superior paste like Kryonaut on your Z790-E, you keep the CPU cooler for longer, allowing it to maintain those boost clocks without throttling. This results in smoother frame times and more consistent performance during long, intense gaming sessions.
Final Verdict
For the owner of an ASUS ROG Strix Z790-E, I strongly recommend Thermal Grizzly Kryonaut if you are using an i9 processor and want the absolute lowest temps. It is the thoroughbred of thermal pastes. If you are building a reliable gaming rig with an i5 or i7 and want a “set it and forget it” solution, the Arctic MX-6 is the smartest choice. Finally, if this is your first build, stick with Noctua NT-H1 for its foolproof application.
