Arctic’s MX-series thermal compounds are among the many hottest, amongst PC builders, and the corporate’s MX-5 is broadly thought of one of the best thermal grease that it produces. However earlier this week MX-5 standing was modified to end-of-life at the corporate’s web site (as found by @momomo_us) as apparently it’s readying all-new MX-6 thermal paste.
The largest shock is that Arctic discontinues its MX-5 nearly 1.5 years after its launch in early 2021 and weeks earlier than AMD and Intel are set to start out promoting their Ryzen 7000-series ‘Raphael’ and thirteenth Era Core ‘Raptor Lake’ processors with elevated most processor energy. But, two photographs of the Arctic MX-6 packages posted by @momomo_us, a high-tech leaker with fame, point out that the brand new thermal grease is incoming.
Arctic’s MX-5 thermal grease is comprised of aluminum oxide, aluminum powder, aluminum nitride, polydimethylsiloxane, magnesium oxide and boron nitride. The paste consists microparticles which fill cavities on the floor of CPU warmth spreaders in addition to cooler bases. Thermal conductivity of the MX-5 is 8.5 W/m-Ok and it has a temperature vary between -40 and 180 levels Celsius, which basically implies that it is not designed for excessive overclocking. It has a viscosity of 550 pascal seconds, which is under that of MX-4, however it’s nonetheless simple to use.
Arctic launched its MX-5 in 2021, however its thermal conductivity didn’t change from MX-4 launched in 2019. Whereas 8.5 W/m-Ok will not be unhealthy in comparison with low cost and mainstream thermal greases, it’s significantly under thermal conductivity of market leaders like Thermal Grizzly’s Kryonaut and Kryonaut Excessive which might be designed with excessive overclockers in thoughts. Typically, the MX-5 shoed excellent efficiency beneath regular situations, in keeping with our score of the finest thermal pastes for CPUs round, nevertheless it appears like Arctic has one thing higher, which is why it replaces the MX-5 whereas holding the MX-4 afloat.
Arctic’s MX-5 didn’t change the MX-4 and the 2 pastes continued to co-exist up till lately, although the brand new one usually carried out higher than its predecessor. In contrast, the MX-6 truly replaces the MX-5.
We do not but know precisely what to anticipate from MX-6, however our hunch inform us that this will likely be a one more all-around performer from Arctic, however maybe designed to higher swimsuit the upcoming CPUs from AMD and Intel. In any case, the brand new thermal grease needs to be out there shortly, so we’re going to discover out quickly sufficient.
