Product Information

For the air cooling low- and high-tension tests, we used a large Noctua NH-D15 air cooler. We created the low tension mount environment by torquing the mounting screws to 1.13 Nm (10 in/lbs). As shown in the slides above, the outcome of the different testing scenarios resulted in some interesting comparisons among the compounds. We’ll look at the overall thermal load averages for each, as well as the relative performance value of each in terms of price-per-gram. The performance value chart shows most of the liquid metal compounds with a poor value-per-gram rating, but once again, Phobya LM proves to be the outlier for that sub-category with its budget price tag. Liquid metal compounds are almost always electrically conductive, so while these compounds perform better than their paste counterparts, they require more focus and attention during application. They are very hard to remove if you get some in the wrong place, which would fry your system.

Small differences in temperatures jostle the chart a bit, but overall the more budget-friendly compounds show much more promising performance value due to relatively close load ranges. We see a trend that most good and great thermal compounds perform very similarly, but might be worlds apart in price per gram. Corsair Commander Pro, 100%/50% PWM Speed profiles (liquid cooling pump always @100%, if applicable) Liquid metal compounds make their way to the top of the temperature chart with slightly cooler values than the traditional pastes. Interestingly, the difference between the top and bottom of this chart is less than 4C. We tested each thermal paste with a low-tension air cooler mount, high-tension air cooler mount, and a high-tension AIO liquid cooler mount. Each application was given a 1-hour burn-in using Prime95 with ten load and cooling cycles over the course of the hour; six minutes each with a ten-second cool-down between. Each testing load session was then executed for a one-hour load period, again using Prime95.Even though a dizzying array of different thermal pastes is available — some blends have been around for over a decade — new formulations still come to market at a surprising pace. Long-time PC cooler maker NZXT recently entered the market with its first paste, the not-very-excitingly named NZXT High-Performance Thermal Paste. Cooler Master introduced a new purple CryoFuze, and Alphacool unveiled its Apex thermal paste. Cooling mainstay Corsair also has a new XTM70 blend that will be heading to our test bench soon, and Gelid has recently released its GC-4 Thermal Paste, showing that the TIM market is still thriving. We'll go into our breakdown of how we test these thermal pastes below, but the key takeaway here is that a single thermal compound can perform differently based upon several variables, such as what type of cooler and mount you use. To cover all the bases, we've tested every thermal paste with three variables: On top of that, liquid metals can't be used with aluminum heat sinks since the Gallium in them reacts with aluminum. That's not really an issue since most heat sinks (remember, not all) are made of copper which is nonreactive with the liquid metal. That being said, the high risk pays off in meaningful ways the liquid metal provides up to 73 W/(mK) thermal conductivity. It's much higher than the 0.5-12.5 W/(mK) thermal conductivity provided by conventional thermal pastes. We're also putting a new take on an old approach to the test — thermal pads. These pads can be used as TIM and come as a single sheet you simply apply to your heatsink, with Thermaltake's Heilos Pad being the first new thermal pad entrant to see our test bed in the coming weeks. Artic's Silver series is extremely popular among enthusiasts. The Silver series has also been around for quite some time now and the company has managed to keep it relevant in the space by adding newer, better variants to match the current standards. The Arctic Silver 5 is currently one of the most popular thermal paste solutions on the market. It's a high-density polysynthetic silver compound that's known to be very effective in a variety of builds. It contains micronized silver and several other thermally conductive ceramic particles to offer a high level of performance and stability.

In terms of specifications, the Cooler Master MasteGel Regular thermal paste has a thermal conductivity of 5 W/mk, which is more in line with a lot of other options mentioned in this collection. The company also sells a premium version of this particular paste with thermal conductivity of 11 W/mk. This paste is grey in color and its density is 2.5 g. We had absolutely no issues applying the paste on the CPU. The overall performance of the solution has also been pretty solid as we've encountered no abnormalities in the CPU temps. We've used this particular paste for many of our builds and it's been a reliable option. I'm not a fan of Thermal Grizzly Kryonaut. The one tube I bought a few years ago was expensive for how much you get, and while it performed well when new, after 6 months temps were shooting up and definitely by a year it needed repasting. They have new formulas now I think, but I still just find their stuff expensive for what it is. It’s no surprise that the liquid metal compounds once again sit atop the thermal comparison. Still, a 6C difference between all 15 thermal compounds tested shows there isn’t a lot of variation, even with a 360 all-in-one cooler with a push+pull fan setup for performance. I've found MX-4 and NT-H1 to stay effective for longer before needing repasting. And honestly between all high performance thermal pastes I don't think you are looking at that much of a difference in performance, and its more about how long it lasts, if you get pump-out effect, etc. The XTM50 paste by itself has low viscosity, so can also just use the 'Dot method' to apply the paste and let the mounting pressure do its thing. But if you're too worried about applying using that method, then the bundled stencil and spreader make it very easy to get things done. In theory, you can use any application method for a compound with low viscosity, but the stencil makes it that much easier to apply. It's for new builders who don't necessarily have the technical know-how of properly applying thermal paste and how improper application can have a lasting impact on the overall performance of the CPU.I'll see how screwed it is soon. I've got a 7700X with some RAM and mobo arriving tomorrow. For now, I just think all current-gen CPUs (both Intel and AMD) are driven way out of their ideal spot on the efficiency curve which can be fixed with Eco mode or some tweaking, but I'll see soon enough.
