I bought two of this tubes but only one tube is sufficient for both graphic card as well as processor. There is enough of it in the tube for two repastes.
Delivery o Australia took 20 days, as per notice on purchase - very good service
I bought all the necessary kit on Amazon (total about $50) after watching an excellent vid on youtube.
I needed the special screwdrivers, the gas duster, the thermal gel, and also I bought a "cooler" platform that plugs into the usb and has 5 fans to keep the underside cool.
When I did the clean-up, and opened the underside panel, it was filthy! After cleaning, I applied the thermal gel, and the result is amazing!
The MBP now just hums along and never slows down.
As a precaution, I downloaded the Mac fan app, and have that set at 6000 rpm constantly (right now the temp is 41 deg C) and the area between the screen and the keyboard that used to get red-hot doen't even feel warm.
The entire process was easy, and I should have done it ages ago!

Ce ne sont PAS des résidus de pâte mais bel et bien une dégradation de la surface
First things thing, I’m rocking a Ryzen R7 2700X at 4.1GHz with a CPU VDD of 1.36v. For cooling, I’m using a Cooler Master MasterLiquid Lite 120, with a Corsair LLL120 fan. As I ran out of my usual Noctua NT-H1, I’ll be putting this Thermal Grizzly Kryonaut against Cooler Master’s MasterGel that I had laying around from the MasterLiquid Lite 120.
Screenshots from HWMonitor included.
I also have a Phanteks P350X case with 2x Corsair LL120 fans in the top, and 2x Corsair LL140 fans in the front.
Unless I did something wrong, which I doubt. It seems as if there’s not a huge difference between the MasterGel and the Kryonaut. Which is a little disappointing. Although I didn’t look at the temps, you’ll have to take my word for it, that the Noctua NT-H1 gave similar temps. Max temps were done with a few consecutive runs of Cinebench R20.
With all of this said and done, I’d honestly say just go for Noctua’s NT-H1. It costs around the same, and you get 3.5g instead of just 1g with this. Although, I will admit, that applying the Kryonaut with the spreader was hassle-free...although could be done something else that’s plastic and has a straight edge.
Sidenote: The CPU and copper plate of the AiO were cleaned with Arctic’s material remover and purifier.
I was initially sceptical when reading about the performance of this thermal paste, however it proved to be as good as is claimed.
I usually use Arctic Silver 5 which kept my CPU (i7 6700k @ 4.5ghz) at around 65 degrees after stress testing for 2 hours with AIDA64. The newly applied Thermal Grizzy Kryonaut saw the temperature drop to 53 degrees after the same stress testing.
I was very impressed and would absolutely recommend this.
Item arrived very fast, less than 24 hours and came in its small black Thermal Grizzly package along with a plastic spatula. The paste seems a bit enlarged in the pictures but it is actually very small. Just 1 gram of that paste, still enough for 4-5 applications. Use only 1 pea size drop on both cpu and gpu, dont put on the heatsink. After you put the heatsink back on the paste will spread equally. There is no downside of putting a little more so if you are in doubt, go for another tiny drop because if you put less than a certain amount, it won't take effect.
After you put everything back together, the temperature change is immediate. I am using a laptop, msi ge73 7rf, gtx 1070 and i7 7700HQ. The idle temps were 60 for both cpu and gpu, the full load temps were 95 for cpu and 80 for gpu. The laptop would get extremely hot and it would burn your finger if you touch the top of the keyboard. The heat would reach to the WASD keys causing uncomfortable feeling. There were 25-30% thermal throttling during full load. After applying the Kryonaut paste, the temperatures dropped 10 to 15 degrees. Now, the idle is 50 for both and full load is 83-80 for cpu and 75 for gpu. I tried overclocking the gpu after seeing such temperature drop and that way the temps only increased 3 degress. I used a heater to heat the room and fan cooler to increase airflow. With fans on full speed and room heated, the temps didn't go above 90 for cpu and 82 for gpu even when overclocked.
The results are shocking, even with overclocking and warm environment, the temperatures were below stock temperatures. This stuff works and it is much safer and easier to apply than liquid metal. Go for this if you don't want any stress and headache just for extra few degrees less.
My OC'ed i7 7700K which would get up into the mid 70s now maxes out at 55 degrees C and idles in the low 30s.
Both PCs are running water cooling solutions form Corsair for comparison.
I'm very pleased and other than going to full liquid cooling this is the next best thing. Just be aware it is very thick and you don't need much - just put a 3mm blob on a patiently spread it with the included spatula. You'll get about 3 CPUs done with the 1g tube and it takes a good 5 minns per application. Just don't rush.
Semplicemente il tubetto da 1g è cosi poco che la pasta si asciuga presto all'nterno(dal tempo di confezionamento alla vendita e arrivo al consumatore) diventando asciutta e gommosa (non viscosa, cose molto diverse).
Il risultato è un tappo termico che peggiora le temperature sia in idle che in full load.
Giusto per confronto (intel 8550u) :
Intel xtu stress test cpu: full-load (boost, no power throttling) 83°C idle 39°C
Ho riprovato con la classica AS5 applicando un velo come faccio sempre:
Intel xtu stress test cpu: full-load (boost, no power throttling) 73°C idle 37°C
Ci tengo a dire una cosa, la conducibilità termica è importante e la kryonaut con 12.5W/m·K ha il miglior valore sul mercato. Ma il problema "geometrico" è altrettanto importante. Se una pasta con 8W/mk di conducibilità la si applica in un velo sottilissimo e uniforme di 20-25 micron(sotto pressione del dissipatore) ha una resa molto migliore di una pasta da 12W/mK che a causa della consistenza rimane dello spessore di un foglio di carta (circa 80micron, sempre a pressione applicata). E poi non fatevi condizionare dai vari test e comparative che mostrano differenze anche di 4-5°C tra una pasta e l'altra. Non è vero, tra una pasta ottima ed una buona cambia una frazione di grado.
La vera differenza la si può fare con metallo liquido (73W/mK), ma purtroppo ha molte controindicazioni, rischi corti circuiti se fuoriesce e corrosivo per alluminio.
Quindi in definitiva, credo sia un problema del formato da 1g. Consiglio il tubo da 11g anche se il prezzo è proibitivo.
Formato da 1g da evitare.
The performance is amazing, i have it on the Intel Pentium G4600 paired with the Noctua LH-L9i inside the Fractal Node 202 and my idle temperatures are 30c while my loads are 60c and i'm not kidding when i say this, my temperatures have never gotten over 60c! Amazing.
Highly Recommended if you want the best temperatures for a price.
EDIT: I got a nt-h1 paste for my cpu but I am keeping the kryonaut for the gpu which stays within low 70s. Compared to nt-h1 I am getting 3-4C less on the gpu with kyronaut and in turn I am getting a better performance. As for the reason, let me explain. Semiconductors are more efficient at lower temperatures, that means they use less power the colder they run. NVIDIA's Turing architecture is power limited on both mobile and desktop, lower temperatures means less power consumption which allows those gpus to run at higher frequencies.
Didn't go too well, with CPU going into 90-degrees (although suspect this might have been due to me using a central-blob) of the provided paste. Tried adding more paste - and didn't really get much better.
Using grizzly and smearing it over the whole CPU - I get well under 70 even under full CPU load.
Still many other things to tweak (wtf is my 4.6Ghz boost AMD?!?!) - but this product has sorted out my thermal issues.
If you are wondering, I did two CPU's with this (Mac Pro 5.1 which has two CPU's). But I did them at the exact same time and JUST managed to get enough for each by putting a bit on each untill I ran out.
For this reason I would say there is only enough for 1 CPU, as it will be very hard to judge if you left enough in the tube for next application and you are most likely going to go over - leaving you in a pickle next time you need it.
Other than that it's good stuff. Lots on YouTube if you want to see it's performance.

Overall I'm happy with the results and will buy again.😀
