For the true "Kryonauts" amongst the "extreme overclockers"

The term "Kryo," derived from the Greek word for "cold," is also used in the German word for "cryoengineering." This implies that the thermal paste may have been specifically designed for use in cryogenic applications.

5.0 out of 5 stars Best paste I've used so far, tried lots.
Reviewed in the United States on June 21, 2017
Edit - I added some images above to show the contents of the package. I have purchased this paste several times now. Best non-conductive paste on the market hands down. (End Edit). I replaced MX2 thermal paste with this, temps went down from 18C idle 32-36c under load on FX6300 with a GTX 1060 on Hyper 212 Evo to 15C idle and 30-34C while gaming. Prime95 before hit 42C now it tops out around 38 hit 40C one time for a second. My 212 Evo has Duel fans in push/pull config. Great paste. Bought it just to try it out before using it on new build I7 7700K and MSI Z270 Gaming M7 motherboard is on the way. Edit 9/2020 - Many years later and this is still the best non-conductive Thermal Paste you can buy. I’ve since got really big into PC gaming and building PCs for people/clients. I currently have new full tubes of Cooler Master Masterpro Gel Nano, Noctua NT-H1, and Artic Silver 5 which is the only one of the bunch that requires a setting time. These are all great pastes. Most people would say the Noctua NT-H1 is the best but from my experience out of the ones listed the Masterpro Nano performs just a touch better but isn’t as easy to apply. I recently upgraded my system. Ryzen 3800XT, RTX 3080 on the way to replace RTX 2070 Super, 32GB G.Skill 3600mhz CL 16 ram, Asus Prime X570-Pro board, several ssds, two NVMe drives one Gen 3 and one Gen 4, a single 500GB Western Digital Black HDD I’ve had since 2013 to use to store backups and gaming videos/pics, a EVGA G3 Supernova 850 watt 80+ Gold Fully Modular PSU, an internal WiFi/BT 5.0 PCIe card all in a Cooler Master Masterbox NR600 Mid Tower airflow focused mesh case with a glass side panel. My case has all PWM premium Noctua Chromax fans. 3x120mm front intake, 2x140mm top exhaust, and 1x120mm rear exhaust. My CPU cooler is Noctua N-DH15S replaced with duel 140mm Noctua Chromax Black/Blue fans, and the Noctua Chromax Black/Blue heatsink covers to make it look nice. Overall I’d say I have a pretty upper mid/high end sustem. I game at 1440p max settings 100+ FPS regardless of the game. I have all these pastes here and I STILL ordered another tube of Thermal Grizzly for my processor. Nothing wrong with the pastes I listed but this pastenhere is amazing and out performs them all. This is in tons of benchmarks just hit up google. It requires no curing/setting time, is non-conductive, easy to apply, and will give you on average an extra 2-4 degrees lower temps on your cpu. That might not sound like much but when you overclock everything and your system draws a lot of power over the course of months, years, and long gaming sessions having a processor that runs cooler is always better. Not only does it allow it to potentially overclock higher as well as boost higher and for longer. But it also if you run your cpu stock allows your cpu cooler to have an easier time cooling it thus your fans can spin at a lower rpm for the same results which equals less power and a silent system. Overall it’s a bunch of minor things that depending on the user might make a nice difference in their setup. For me spending 8-9 dollars to have the best possible paste I can buy is a no brained. A single 1 gram tube is enough to do 3 applications easily. With my mentioned system above using my case which has great airflow with my Noctua N-DH15S in push/pull my CPU runs in the lower 30c idle, around 50-55C in games maxed out no matter how long I play, and using Prime95 max power max heat stress test after 20 mins which is enough time to hit its top out point it peaks at 68C. That’s on a Ryzen 3800XT that’s set to run wide open with all I could get out of it. You will not fine a better non-conductive Thermal Paste so if the best is what you’re after proceed to hit the buy button.

5.0 out of 5 stars Unleash Your PC's Cooling Potential
Reviewed in Canada on July 3, 2023
As an avid PC enthusiast, I understand the importance of maintaining optimal temperatures for peak performance. Recently, I decided to try the Thermal Grizzly Kryonaut High-Performance Thermal Paste, and I must say, I am thoroughly impressed with the results. In this review, I will share my experience with this thermal paste, focusing on its performance, ease of application, and overall effectiveness.

Performance:
Thermal Grizzly's Kryonaut lives up to its reputation as a high-performance thermal paste. It boasts exceptional thermal conductivity, allowing it to efficiently transfer heat away from the CPU or GPU to the heatsink. During my tests, I noticed a tangible reduction in temperature, particularly under heavy loads and during prolonged gaming sessions. The improved thermal conductivity contributed to more stable system performance and mitigated any potential throttling issues, ensuring my PC operated at its best.

Ease of Application:
One standout feature of the Kryonaut thermal paste is its ease of application. The syringe packaging and included spreader tool made the process simple and mess-free. The paste's consistency is ideal, allowing for precise and uniform spreading across the processor's surface. Its non-conductive nature provides added peace of mind, as there is no risk of short-circuits should any paste accidentally come into contact with surrounding components.

Longevity and Durability:
Thermal Grizzly's Kryonaut is known for its long-lasting effectiveness. After several months of use, I found that the paste maintained its thermal properties without any noticeable degradation. This durability ensures that the thermal paste will continue to provide reliable heat dissipation over an extended period, eliminating the need for frequent reapplication.

Versatility:
The Kryonaut thermal paste is suitable for a wide range of applications, including CPUs, GPUs, and even other components requiring thermal interface material. Its versatility makes it an excellent choice for various PC building and upgrading projects. Whether you're a casual user or an overclocking enthusiast, this thermal paste caters to diverse needs.

Value for Money:
While the Thermal Grizzly Kryonaut may be priced slightly higher than some other thermal pastes on the market, its exceptional performance, ease of application, and long-lasting effectiveness justify the investment. The improved cooling capabilities translate to better overall system stability and longevity, making it a worthwhile upgrade for any PC enthusiast seeking peak performance.

Final Thoughts:
In conclusion, the Thermal Grizzly Kryonaut High-Performance Thermal Paste has exceeded my expectations. Its outstanding thermal conductivity, ease of application, durability, and versatility make it an excellent choice for anyone aiming to optimize their PC's cooling potential. If you're looking to achieve lower temperatures, improved system performance, and a reliable thermal solution, the Thermal Grizzly Kryonaut is undoubtedly worth considering.

Disclaimer: I purchased the Thermal Grizzly Kryonaut High-Performance Thermal Paste independently and did not receive it as part of any specific program or incentive. My review is solely based on my personal experience and observations with this thermal paste.
