The media could not be loaded. Kryonaut lives up to its reputation as a high-performance thermal compound. I’ve used it across multiple devices, including a laptop CPU and a console GPU, and in each case it delivered a noticeable drop in temperatures compared to the stock paste or older, dried-out compound. The consistency is slightly thicker than average, which helps it stay in place during application, especially on vertical surfaces or uneven heatsinks. It spreads best using either the pea-sized dot method or a very light pressure spread—no need to cover edge to edge manually, as the paste distributes evenly once pressure is applied. The included applicator is optional but useful for more controlled setups. In terms of results, thermal performance has been solid across the board. Under load, temperatures stayed consistently lower, and fan ramping was reduced as a result. It's especially effective in compact systems where heat tends to build up quickly and small gains in efficiency make a noticeable difference. No curing time is needed, and there’s been no sign of pump-out or drying, even after extended use. One gram is enough for a few applications depending on how much surface area you're covering. It's a good size if you're repasting one or two components and want a compound that performs at the high end of what's available without getting into liquid metal territory. Overall, Kryonaut is an excellent choice if you’re doing a repaste on a CPU, GPU, or other performance-sensitive component. It's well-suited for overclocking, high-load systems, or just improving thermal efficiency in aging machines.

I've heard about this paste long ago, but thought the price was ridiculous and all thermal paste was the same. My GPU was having overheating issues and I repasted it 2 times with my MX-4 so I decided to give this a try and I was not disappointed. My GPU idle times went down around 20C and temps went down quickly after heavy gaming. I also decided to try this on my gaming laptop with similar results. Is it worth the price? For my experience yes it is worth it.

Thermal paste worked. Easy to apply and has brought down my CPU/GPU temperatures. Prior to this, my laptop was running hot on the CPU (90-100+ Celsius) even with fans blowing full throttle. After application, they now top at 90 Celsius at full throttle. I have an Alienware M15 R3. Granted, I also replaced the thermal tape on all the memory chips and fans since the fans were starting to make some funny noises.

Outstanding!!!. It could have been just a little bigger for what it cost. But my cpu is some cool now. I don’t even have to use my ac anymore. Really dropped my cpu temp by 10 to 15 degrees. Works well

I'm no computer guru, but this paste has made a difference. I have an old computer (2012) and realized the heat sink had never been changed or had the paste replaced, and I was regularly overheating to 91C+, so I ordered this paste so I could reseat it. The syringe was a lot smaller than I expected, but it only took about half to get the coverage I needed. It stuck to the spatula more than I would have liked during spreading, but I used a second tool to scrape off the spatula and apply the remaining paste to the CPU. I don't know if it's the paste or the slightly less old heat sink (2014), but now I'm running around 32-35C average and around 65C under heavy load, so I'm really happy. In retrospect, it seems a bit expensive for how little you get, but we'll see how well it lasts over time.

The tube is a lot smaller than I initially thought but had just the perfect amount of thermal paste for one application. The computer is running smooth without hiccups, and the paste is of excellent quality and spread nicely.

The Thermal Grizzly Kryonaut 1 Gram Thermal Paste is awesome for keeping my CPU chill. It’s easy to apply with the included spatula, and I noticed a solid 5-10°C drop in temps right away. Works great for gaming and overclocking.

Great product, Haven't had any cooling issues with this product, I bought the bigger tube because I knew I'd be building 3-5 PC's within a year & it did not disappoint, I finally ran out on my 4th PC build and I'm a little more generous with CPU paste.
