Arctic MX-6 Thermal Grease to Replace Storied MX-5

Arctic’s MX series thermal compounds are the most popular among PC builders, and the company’s MX-5 is widely regarded as the best thermal grease the company makes. But earlier this week, MX-5’s status company website (as discovered by @momomo_us) Apparently the all-new MX-6 thermal paste is ready.

The biggest surprise is Arctic’s MX-5 nearly 1.5 years after its early 2021 launch, weeks before AMD and Intel start selling their Ryzen 7000-series ‘Raphael’ and 13th Gen Core ‘Raptor Lake’ processors. to stop at Increased maximum processor capacity.Still, two images of him of the Arctic MX-6 package posted by @momomo_usA reputable high-tech leaker indicates that a new thermal grease is coming.

Arctic’s MX-5 Thermal Grease is included This paste of Aluminum Oxide, Aluminum Powder, Aluminum Nitride, Polydimethylsiloxane, Magnesium Oxide, and Boron Nitride consists of fine particles that fill the surface cavities and cooler bases of CPU heat spreaders. MX-5 has a thermal conductivity of 8.5 W/mK and a temperature range of -40 to 180 degrees Celsius. This essentially means it’s not designed for extreme overclocking. It has a viscosity of 550 pascal seconds, which is lower than MX-4, but it is easy to apply.

Arctic introduced the MX-5 in 2021, but its thermal conductivity remained unchanged from the MX-4 launched in 2019. 8.5 W/mK is not bad compared to cheap and mainstream thermal greases, but well below the thermal conductivity of market leaders such as: Thermal Grizzly’s Kryonaut and Kryonaut Extreme are designed with the extreme overclocker in mind. In general, the MX-5 performed quite well under normal conditions according to our evaluation of the best thermal pastes for CPUs, but Arctic seems to have something better. -4 Float.
