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

5 out of 5 eggsBest & Safest Paste

Pros: This is the best thermal paste you can buy. There are many comparisons and this paste is always at the top along with whatever paste the reviewers are trying to push. There is a reason they always include this paste....it's the best. Just check the "Thermal Conductivity" (higher is better) and the "Thermal Impedance" (lower is better) against ANY other paste.

Cons: It's a bit thick to use. Put it in a water tight plastic bag and warm it in 160 degree water before you use it. Also, DON'T try to spread it. Just use the pea size dot or for socket 2011 use a line.

Other Thoughts: CoolLaboratory Liquid Ultra DOES work better. It's also liquid metal and very dangerous to use. One spec of it in the wrong place and you could short out your motherboard or CPU. Not worth the risk.
IC Diamond has a Thermal Conductivity of 4.5 W/m compared to PK-3 of 11.2 W/m.
IC Diamond Thermal resistance is 0.25 compared to PK-3 of 0.013. How is IC Diamond better, feniks?

5 out of 5 eggsBetter than PK-1, but only by 3 degrees

Pros: All the pros already mentioned by others.

Temps on an i5-3210m in a Lenovo G780 laptop have changed after switching from Prolimatech PK-1... Max temps dropped 3 degrees, and idle temps by 1. This is comparing 8 month old PK-1 to a brand new application of PK-3.

Cons: Took 6 months for Newegg to restock so I could get some.

Other Thoughts: If you're looking for the best non-glue TIM, this is it. There are a few others that will glue the heatsink to the chip, but they only improve the temps by 2 degrees at most, and only if you apply them exactly right. (not worth it IMO, and you don't get retries)

If you're trying to decide between this and PK-1 or PK-2, get this. It's only a couple bucks more, and you'll drop temps over the others.

Also, THERE IS SUCH A THING AS TOO MUCH THERMAL GREASE!!! Make sure you get as much surface contact as possible between the heatsink and chip, but the less TIM you use, the better. If you use too much, it becomes an insulator instead of a conductor.

5 out of 5 eggsGreat Thermal Paste

Pros: *syringe was packed in its own box and it was then placed in a USPS bubble wrap envelope

*5 grams is enough to easily do 20 CPUs if you use the grain of rise method

*comes with a little plastic trowel if you like to use the old school application method

*not too thick, not too runny

*much better than your generic paste that comes on stock heatsinks and graphic cards

*non-conductive so you can use it directly on the die and not just a heat spreader

*much better thermal conductivity than Arctic MX-4 (8.5 W/m vs. 11.2 W/m)

Cons: *brand sticker does not stick too well and was wanting to fall off the syringe

*Prolimatech states that it requires no burn-in time, but I have found that the temperatures do get lower after a week or so

Other Thoughts: Here are the results of my findings, before and after changing the TIM. The CPU is an old Athlon 64 x2 6000+ with a heatsink fan that came off a 4000+. Because the heatsink was smaller than what comes stock with the 6000, I needed a good paste for heat dissapation. If you want the best, this is the paste to get.

Temps of CPU using old generic TIM:
Idle: Core 0 - 48C
Core 1 - 46C

Used Prime95 (in-place large FFTs)
Load: Core 0 - 80C (heatsink fan hits 100% speed)
Core 1 - 74C

Temps of CPU using Prolimatech TIM:
Idle: Core 0 - 48C
Core 1 - 46C

Used Prime95 (in-place large FFTs)
Load: Core 0 - 75C
Core 1 - 72C

Temps of CPU using Prolimatech TIM for 2 weeks:
Idle: Core 0 - 40C
Core 1 - 42C

Used Prime95 (in-place large FFTs)
Load: Core 0 - 68C
Core 1 - 73C

5 out of 5 eggsfirst time user

Pros: * Spreads easily
* Great thermal conduction
* Not electrically conductive
* No burn-in

Cons: * Price, but who cares?

Other Thoughts: This compound seems to have it all. For a first-timer who didn't want to jump through a bunch of hoops to get it working, this was perfect.

AMD FX-8350 at stock settings, with Antec Kuhler 920:
Ambient T: 24*C
Prime95 max T: 48*C
