5 out of 5 eggsTHE BEST!

5 out of 5 eggsVery conductive

Pros: Very good thermal conductivity.

Cons: None

Other Thoughts: I doesn't use spool because I had more change to put air bubble between CPU and cooler, I prefer make a X and make a little chuck in the middle and spread it directly with the CPU cooler when I install it.
Warning: aluminum is conductive!

5 out of 5 eggsDependable, high quality paste

Pros: Prolimatech PRO-PK3-5G is a top quality thermal compound that doesn't disappoint. I have used this product on several of my overclocked 8-core Amd's and have been completely satisfied with it's performance. The thermal paste spread very evenly and requires a no cure or burn in time to achieve maximum results. If your not getting good results then chances are your applying it wrong. It's a great value for your money! Most paste people are claiming to be better usually cost 20-25% more, but only gain you a few degrees in temperatures.

Cons: None so far.

Other Thoughts: Remember any paste only serves as a medium to transfer heat and fill the micro gaps and imperfections between the CPU/GPU surface and its attached coolers face. In the end diamond encrusted, carbon impingement, ect fancy paste gain you very little for the extra cost.

5 out of 5 eggsSafest Thermal Paste

Pros: Really easy to apply,non electrically conductive and drops temps by up to 16 degrees celsius from stock paste! Not as good as Coolabs Liquid Ultra or IC Diamond 7 but unlike Coolabs liquid ultra you can use it more then once and it don't eat through aluminum also it don't scratch heatspreaders like IC Diamond 7 does (found this out the hard way had to lap a heatspreader on cpu after taking off IC Diamond 7) anyways comes in a good quantity as well enough for like 40 applications if you use the grain of rice heatsink smash technique I never spread it so the spatula is worthless to me (might good work good on intel that way I don't know I don't use Intel and rarely work on Intel Powered Computers) Anyways Yes the best thermal goop they make in my opinion for its ease of use and being non electrically conductive! Really good thermal conductivity as well!

Cons: May be a little hard to get out of tube if it sits for a while from what other people have told me! I myself never had this issue so I am not docking an egg for that!

Other Thoughts: Best of the best,DO NOT USE ARTIC SILVER 5 it is electrically conductive so if you spill it on a component accidently good bye pc! also DO NOT USE IC Diamond 7 as it scratches heatspreaders and DO NOT USE Coolabs Liquid Ultra (It dries out after a year takes a pocket knife to remove and will destroy aluminum) Prolimatech Pro PK-3 For the win!

5 out of 5 eggsHighest Rated Thermal Compound

Pros: According to all the research I've done Prolimatech PK-3 is the most consistently efficient thermal paste available. Is it the best? I don't know that for sure. I just know that it comes in the top 3 for every comparison among the most popular brands. And since its the only one that consistently ranks among the top performers, I'd say that it's a good chance.

This is the first time I've ever used it. However, it was significantly better than the thermal paste I was using, which was provided with my water block. I recently built a z97 system with a 4790K and I was determined to achieve the maximum over clock.
Original compound results, average temperatures in Celsius under full load with running Prime95 small FTTs setting:

Idle - 28c
4.4 GHz, 1.200v - 66c
4.7 GHz, 1.275v - 82c
4.8 GHz, 1.325v - 90c

Results with the Prolimatech PK-3:

Idle - 24c
4.7 GHz, 1.275v - 73c
4.8 GHz, 1.325v - 83c

It's clear that the PK-3 was a significant improvement over the typical paste. Dropping idle temps by 4c when you're already below 30c is really impressive.
One of the great things about this tube, is you get enough to do at least 20 CPUs, GPUs or other chips. I plan to use it on everything I own as I eventually tear down my rigs to clean them.
For the price you really can't beat it. You can extend the life of your components or increase the potential of your over clocking for a few bucks.
No burn in required. You can just apply it and go. It's also electrically non-conductive. Which is a feature I demand in my thermal paste. It's not at all difficult to accidentally drip a bit of thermal paste where it doesn't belong.

Cons: This stuff is difficult to properly apply. When you squeeze it out of the tube it comes out and appears thin, but when you go to spread it out you'll find that it's actually quite thick. I had a hard time getting it to spread out evenly. When I use thermal paste I apply a thin, even layer to the chip I'm using it on. There are a number of ways to apply thermal paste, but I prefer this method. Spreading it out wasn't difficult, but getting it even across the entire surface was. It just wanted to stick to the spatula like utensil they provided to apply the compound.

Other Thoughts: Recently it has occurred to me that each and every component in your cooling loop is equally important. Until now I never really gave much thought to the difference between all the various thermal pastes. But if you're willing to spend a few hundred bucks to keep your temps and noise levels down and your clock speeds up then you should have the best thermal paste doing the work for you. For the price, it would be foolish not to.
Unless something even better comes along that can consistently rank among the top performers, I don't plan to use anything else. I'm sold on this stuff.
For those people who would prefer a paste that's easier to apply the PK-2 is supposed to be much easier to apply with only a very sleight decrease in thermal efficiency.

5 out of 5 eggsA+

Pros: I applied the TIM to my overclock CPU (I7 4770k @ 4.5GHZ), my graphic card (GTX 770) and even my laptop. The temperature is indeed lower. For the CPU, it's lower than Artic Silver 5 which I applied before.

Cons: Hard to open at first.

Other Thoughts: I used PEA method.

5 out of 5 eggsSlightly better than PK-1

Pros: High thermal conductivity.
Electrically non-conductive.
5g container.
Low price for the quantity.
No burn-in time required, but there is a slight decrease in temps after a few weeks.
Is still a fluidic compound after 6 months of gaming.

Cons: None.

Other Thoughts: Used for processor, video card, and some other small components in a Lenovo G780 laptop. Dropped temps by 5-7 degrees C over the OEM compound, only about 1c-2c over PK-1. (but it went on better)

Compared to the AS-5 that I have used in the past, this gives between 3c and 7c better temps, doesn't dry out, and doesn't require a burn-in.

Remember, less is more when it comes to thermal compound... If you put too much, it becomes a thermal insulator instead of a thermal conductor. Use just barely enough to cover all contact points between the heatsink and whatever components you're using at thinly as possible. You may have to wipe some off if you put too much, or push down the heatsink so that it squishes the excess compound out.

DO NOT PULL THE HEATSINK OFF AND REAPPLY IT AFTER YOU APPLY THE COMPOUND! It'll create air bubbles, and reduce the thermal performance.

4 out of 5 eggsProlimatech PK3

Pros: Non conductive, spreads and cleans easily

Cons: Too thin, runs, does not hold together well enough under high heat conditions.

Other Thoughts: I used the top arctic silver product exclusively for years and I will continue to do so. I've installed many processors with silver 5. Recently I tried PK3 on my new late 2013 macbook pro w/2.6ghz i7. This processor runs hot and I have seen temps hit 99C on occasion. When I applied PK3, temps were good. I then checked the heatsink and noticed that the PK3 has ran and became very thin at spots. Coverage was not even, even though I did a good application. Next I tried silver 5. It gave me better temps by a few Cs. Most importantly since its thicker, it holds together better under high temperatures. Apparently silver 5 is still king for intensive use.

5 out of 5 eggsamazing!!!!

Pros: ps3 fixed no loud fan, CPU >107°F full load AMD phenom II x6 black edition no o/c with the thermaltake water performer 2.0 and corsair performance pressure optimized fan between 50-75% fan speed witch I barely hear, water pump always at max speed to quickly pull heat away. idle gets down to 68°F. GPU with crummy stock cooler doesn't see 140°F anymore at a fixed fan speed of 50%. laptop quiet, netbook quieter, Wii not as warm, will use on ps4 in future

Cons: none what so ever.

5 out of 5 eggsCool Temps

Pros: Keeps my temps down, played Starcraft II and temps never went over 45 celsius. just heat it up in boiling water to spread it easier.

Cons: none

Other Thoughts: Running AMD 8120 FX Watercooled
