Good stuff!
I wanted to give this a try since i find repeatedly online that this has the best performance. I started out last year with arctic mx-4 on a ryzen 9 5900x cpu and a custom built water cooling system and my own coolant formula. Highest temp under load was 71c, no load 41c. 2 months ago i tried the arctic mx-6. It was hard to spread and high temp went down to 63c, low temp 40c. Yesterday i put this stuff on and what a difference. The highest temp measured: 57c, lowest temp is near ambient air at a whopping 38c. Tests were performed using DCS in VR mode gaming, and Daz3d for design. Daz put more load on the cpu as well as gpu. In game temp on dcs was 57C using multithread. While i think the price is a bit high, its a good product. Ive worked on computers since 1991 and wish this was around back then.

Probably one of the best thermal pastes around without going into exotic materials territory.
Like the title says, this is one of the best "normal" thermal pastes around. It consistently ranks within the top 3 of thermal pastes in every test and benchmark I could find online. Anything better is Diamond IC and Coollaboratory Ultra/Pro. Diamond IC uses tiny diamond particles but it also has a reputation to pit, or make little dents in your die or contact plate. Diamond particles if clumped together don't really compress well I suppose. I have Coollab Ultra and it is a great but it is also conductive and cannot be used with aluminum or any aluminum alloys. I use it between my CPU die and IHS but I can't use it on my video card because it has exposed circuits that it will short out. Even though PK-3 doesn't perform as well as the previous mentioned, it's only like 2-3 degrees difference which isn't terribly much. I did a LOT of research before purchasing this. PK-3 is non conductive and I can put it on circuits, between the IHS, on aluminum, nickel,copper, anything that needs good cooling. PK-3 consistently ranks within the top 3 of benchmark tests. The product is pricey though. I used to have the 1.5 gram version and that was only good enough for like 3 applications. The 5g tube will last you years and years. ***Update 12/3/2018*** After having this tube for 4 years now, I still have about 1/3 of a tube left. I've used this on countless computers including desktops, laptops, even GPUs. My experience over the years was that this stuff doesn't really dry out as long as you keep it in the syringe and cool and out of the sun. I have not noticed any noticeable temperature difference with my overclocked gaming CPU. I repasted it one year ago just because I had so much of this stuff lying around that I figured it wouldn't hurt. That was 3 years of undisturbed paste job! One thing I can say is that the consistency of the paste is "drier" and harder to spread compared to other pastes that may be more "liquidy." I would say the consistency feels like dry wall spackle - not exactly hard, but not liquid. Additionally I've noticed mounting pressure is also an important factor with this paste. Maybe because it's not a soft or liquid paste, you need strong mounting pressure, usually from a desktop or AIO cooler to really push the paste down and spread it. I've noticed the mounting pressure from most laptop coolers are not enough. In 2018 there are definitely better pastes available, Grizzly Kryonaut is the top name being used these days. Grizzly is a much more liquid paste and easier to spread. However in all comparisons and tests PK-3 is still around 2-3 degrees difference in performance during load. The paste holds up quite well even today. I would say though, the price should be decreased due to the competition. Advantages: + Great cooling performance + Very generous amount will last you years + Does not seem to dry + Does not need reapplication even after 3 years Disadvantages: - Price, it's costly and in 2018 where there's better pastes out there, the price needs to drop - "Dry" consistence. Not easily spread. - Needs high mounting pressure.

and either Arctic MX2/MX4 and purchased the Prolimatech Pk-3 for better thermal conductivity
Generally I use TIMs such as Noctua, and either Arctic MX2/MX4 and purchased the Prolimatech Pk-3 for better thermal conductivity. I have found this to be slightly thicker than the ones previously mentioned, and seem to get better performance and temps, especially with heatsinks that have copper pipes and ones that don't provide a lot pressure. Certainly it is a bit more expensive than others, and also non-conductive, but while GPU folding for FAH (99% load 24/7) 3-5 degrees better cooling performance on average is very noticeable and would def recommend.

Great quality
I bought this to build a computer with, but I didn't get that far. So, my husband used it to pull apart and clean, and then reassemble his PlayStation instead. It spreads well, and it disperses the heat perfectly to prevent overheating. It's easy to use. Easy to clean up if you get some where you don't want it. And a fantastic price for a quick and easy product.

So good Thermal Grizzly copied it!
I’ve always read about but never used it. Grabbed a tube and applied to my 9800XD and wow. Idle temps are 28c and under load I’m lucky to see high 40s while gaming. I see some saying it’s hard to spread and it’s not. If you’ve ever used Noctua NT-H1 or H2 you know how well spreads and this is comparable. Maybe a tad thicker but not much. Great paste and now my new go to. Even better than FuzeIce and Thermal Grizzly copied this and calls it Duronaut. Grab this!

So far very happy with this alternative to AS5 on initial application.
I've been a long time user of Arctic Silver 5 since probably my first builds over 15 years ago. But this time around I wanted to try something different as I found that AS5 has an excellent level of performance when new, but starts to fade as it has an unfortunate tendency to dry out. While I just barely got this, comparing two more or less similar builds with similar but not identical cases and heat sink and fan assemblies I have this to report on initial use: Intel Core i7-4770 @ 3.4GHz (stock speed) in a Shuttle PC with stock ICE cooler idle temp of 30 degrees C with AS5 Intel Core i7-6700K @ 4.0GHz (stock speed) in a Shuttle PC with stock ICE cooler idle temo of 25 degrees C with PK-3 Granted they are not the exact same CPUs (one is 22nm the other 14nm) and the newer Shuttle has 1 more heat pipe in it's cooler setup and the ambient temperatures are different by about 5 degrees F. The only other major difference is that the AS5 in the older CPU was applied about 3 years ago now, so some level of deterioration is to be expected. What I hope to see in 3 years is that the newer CPU is still below the 30 degree idle temps mark (preferably within a degree or two of the original 25).

Seems to be the best available balance of performance:cost, safety, and ease of application.
This is good stuff. Sadly I don't have hard numbers to share since I used this in a build with all new components, but it seems significantly more effective than the MX-2 I was using before, and the benchmarks available elsewhere definitely corroborate that. My only concern when ordering this was not knowing what to expect in terms of consistency. Some users report that it's fairly clay-like and hard to spread until they heat it up. I didn't have this issue at all, and the consistency was exactly what I'd expect of a thermal compound. It was about the same as any of the Arctic products I've used in the past, or maybe just slightly thicker. I didn't have to go out of my way to heat it up or anything like that, and letting my CPU cooler do the spreading was not an issue.
