A Canadian based high-performance desktop and notebook manufacturer Eurocom has confirmed about Intel Core i9-9900K and Core i7-9700K having its IHS soldered. Soldered IHS, in comparison to thermal paste applied solution Intel is running with for many years since Ivy-Bridge, have a much better contact and therefore better heat dissipation to draw it out from the core and spread it across its integrated heatspreader effective.
About thermal performance problems and delidding kits
Over the period of time, many enthusiasts have criticised Intel but nothing really came out of it. Eventually delidding such desktop processors to apply better cooling thermal pastes like Thermal Grizzly Conductnaut liquid metal (INDIA | US | UK), if not thermal pastes. Still, this ends up voiding the warranty of very expensive desktop processors but Intel’s pre-applied solution had major trade-offs such as bad heat transfer and limited TIM lifespan, as we have seen Intel not recommending overclocking for its 7th generation flagship Core i7-7700K. Eventually, Intel said it was going for a better thermal paste option for the 8th generation but that was still not good enough. Clearly, the fluxless soldered option was the only best option for mainstream enthusiast series CPUs.
As a result, delidding/resealing tools and liquid metal kits have grown popular. AMD Ryzen and Ryzen 2 are soldered, so this solution applied only for unlocked Intel desktop CPUs.
Eurocom states this via Facebook:
New Intel i9-9900K and i7-9700K CPUs are coming with gold soldered TIM/IHS to the CPU die. This should help manage the temperatures of the higher-clocked CPUs and will also help with achieving higher overclocked frequencies.
While there has been news of soldered IHS for the Core i9-9900K, the fate of the Core i7 and i5 was unclear. Now that there is some confirmation from an established high-performance system builder, Intel 9th generation is something to look forward to thanks to no-hassle heat dissipation standard. Let’s hope it applies to the Core i5 series as well!
