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. Whether you opt for the MX4 thermal paste or some other brand and model, there are certain features to watch out for. To that extent, here are a couple to ease your search for the best paste. We like that the paste uses a micronized silver paste alongside ceramic particles to create a high-performance and durable design. Parts of the composition of aluminum oxide, boron nitride and zinc oxide solution will provide lower load temperatures than you’ll get from standard compounds. – Coverage Area: Covers a Wide Spot

Unlike its Silver 5 counterpart, it doesn’t need curing for long hours for optimal performance. The Silver 5 requires up to 200 hours, thus it can represent a higher commitment than you might like. We must also state that there are many thermal pastes on the market, which have the job of lowering the temperature of your computer by more than a few degrees. Degrees here sound small, but even if you’re not an ardent gamer and enthusiast, you might know that a minor change in temperature can make a world of difference. Going by our Arctic Silver 5 review, we can say that it’s the perfect thermal paste for users who perform CPU-intensive tasks and functions. It’s the ideal choice to keep your system cool and running. 2. ARCTIC MX-4 (incl. Spatula, 4 Grams) – Thermal Compound Paste ProsThe wipe is made of 100% Limonene extracted from citrus essential oil. This would mean that these wipes don’t have alcohol or benzenes as this substance is used in industrial applications for cleaning as it is effective and gentle on metals and alloys. We like that the Arctic MX4 performance is built to last over time. According to Arctic brands, you don’t have to reapply for up to eight years.

You also get effective cooling for an enormous number of surfaces before the tube is exhausted. Also, it’s an oil-based paste that is better than what you’ll find in less expensive thermal pastes.

Best Thermal Paste for CPUs and GPUs In 2023

If you apply Arctic Silver 5, you’ll notice that it has a high-density filling of micronized silver and enhanced thermally conductive ceramic particles. As such, it provides a new level of performance and stability for your CPU. Price is usually commensurate with the amount and efficacy; although, brands can sometimes charge a premium for their name, as with any product really. That being said, it’s usually still reasonable. These two thermal pastes are excellent additions to your rig and computer. However, we are going to pitch our tent with the MX4. It has better all-round delivery on temperatures and performances.
