It's time for the numbers. In addition to testing liquid metal compounds and thermally conductive adhesives, each paste is discussed on its own merits before we chart out the results of four usage cases. After all, these products behave differently.

Results: CPU Air Cooler; Low Mounting Pressure

One last time, we covered this configuration in Thermal Paste Comparison, Part One: Applying Grease And More. This chart reflects our air-cooled machine with lower mounting pressure.

    I loved the toothpaste part. What about Vicks Vaporub? I wonder how that thing would do.

    Great article guys! As a reader for over 10 years pretty much daily, this reminds me of the old Tom's Hardware. These type of in depth articles on enthusiast products are what I love.

    A great article, agree the application of the compound, not the compound itself is most important.

    Like ledpellet I too am curious about these diamond compounds. Wonder if it offers similar results to the Coollaboratory products with an easier application, or if the results simply don't justify the price. E.g in Australia, Innovation Cooling IC7 Diamond 7 Carat Thermal Compound Paste - 1.5G can be found for as much as $25. The cheapest I have managed to find it for is $15. For that price it would want to be good considering the leading GELID GC Extreme, can be found for around $8.

    Coollaboratory Liquid Ultra isn't all that good after a year of hard use. In fact, it completely hardens / dries. On my X9100 after 9 months of nearly 24/7 100% load, I started seeing high temps and after 1 year auto shut downs while crunching. Turns out it was shutting off because it hit the 105 C thermal protection.
    Opened it up; thermal compound was as hard as a rock. has to pocket knife blade and sand it down.
    So for longevity it sucks. That is something to consider, not just initial performance, but performance months and years down the road. Especially for laptops that aren't designed to be opened up frequently for repasting.

    After trying Liquid Ultra many times and having it fail on me, I've put on Arctic MX-2 that has a supposed 8 year durability rating. Initial performance is great, we'll see how it lasts (been 3 weeks so far).

    CLU and Arctic MX-4 are both great products. MX-2 and MX-4 can often be found free after rebate so they are an exceptional value.
