    Not sure why the pictures show the syringe applicator. The 9mL version actually comes in a jar with three spatulas. See the TG product page or the Australian PC Case Gear reseller's page. The 2g version comes in a syringe though.
    Also, 14.2 W/mK for the Extreme versus the 12.5 W/mK for the "normal" Kryonaut... Wonder how much difference that actually makes?

    As the the name and description says, it's mostly intended for extreme overclocking (sub-zero), due to stability at very low temperatures ...
    ... not a product for everyday usage.

    I have the "normal" Kryonaut on both my CPU and my GPU and it's working as intended, shaved a few degrees in load temp from the stock paste. Is that much difference ? Not really... but if possible, why not ?

    Shall try some of this next time I get ln2, so far preferring KPx over Kryo, maybe this new paste from Roman will convert me back to Grizzly

    I can report a nice temperature drop on my friend's RX470 GPU. Since it was brand new under OC it gave out max temp around 74 degrees C. After changing the paste to Kryonaut with max OC under stress test the temps don't go over 66-67 C.

    On the other side, when applied to a normal CPU there is maybe a 2-3 degree C difference and i am using it with my AIO. The thing i love the most is no need to change it since it is incredibly stable and there is no curing time...from the moment you put it on it gives max performance immediately.

    To sum it up...amazing results when used in direct die contact applications such as GPUs, laptops, delidded CPU or anything alike, and above average performance when used on a regular CPU with an IHS.
    All in all an amazing product!

    Very expensive stuff and only for kids trying to get attention with OC records.
    Interesting that there are awesome products available, even if it doesn't make sense for the average John.

    Just checked prices for other compounds and omg if the law of diminishing returns doesn't hit fast! You can get 4g of CoolerMaster MasterGel for 5€, and that's 11W/mk!

    I use Artic MX-4 (8.5W/mk), I've had this 4g syringe forever (I used it on my i5 2500k) and performs awesome every time I use it.
    When I got my 2600 I wiped the stock thermal paste and applied this, happy CPU!
    Also cleaned and applied on an RX560 and later sold it, was happy too!

    You don't need liquid metal, or absurdly expensive stuff. Just look for the best bang for your money.

    used to use a lot of thermal grizzly, but tend to use thermalright now, their TFX paste is 14.3, decent stuff. Using thermalright's TF8 at the moment which is 13.8.

    Tbh for daily use or binning CPUs or GPUs I just use MX4, though I have just taken receipt of 60g of GD900 that cost like £6 so looking forward to see how it compares to MX4

    As for grizzly and KPx they really are more geared for xoc use and I pretty much will only use those products now for subzero as it does genuinely make a difference to your top clocks otherwise I could never justify spending that sort of cash on thermal paste

    I never tried KPx and can't comment how it performs, many people use rather KPx than Kryonaut

    Currently trying ZF-EX(bought it over Aliexpress) which is repacked Thermalright TFX and seems is like 1-2°C better than Kryonaut

    For normal GPU or CPU testing I use just Noctua NT-H1 which is performing like 1-2°C worse than Kryonaut on CPUs and on GPUs that depends, on Pascal GPUs Noctua NT-H1 is like 1-2°C better than Kryonaut and on Turing or Ampere Kryonaut is performing better than NT-H1

    Hope this helps

    Thanks, Jura

    From what I have heard this stuff is only like .25 to.5 C better than the regular Kryonaut and gets beat by KPx. Some guy on Youtube reviewed the stuff in September while it was still not very available in the US.

    I now use that coolermaster and it's a great paste.

    No regrets.

    I'm glad someone else noticed that ZF-EX Thermagic is TFX rebranded. I think I was the first to ask Luumi about that when I noticed they were the same color and that Thermagic seemed to have similar paste tiers as Thermalright. Which suggested that they were rebranding it either from Thermalright themselves, from their supplier, or "Thermagic" is somehow related to thermalright by name?

    TFX is excellent paste and I used two syringes already. But at $40 for 6 grams, it's WAY too expensive if you are constantly repasting. And since i already paid $80 for two of them, I went ahead and just got the 33 grams of Kryonaut Extreme for $104. A lot more paste per dollar spent compared to TFX.

    KE seems to be about the same performance on my shunt modded RTX 3090 FE as TFX. With both being several C better than the old Kryonaut.

    what was the name of that cpu kit where you had to run the cpu at high temps to melt the metal onto the cooler.
