While Intel has no plans to switch their high-end or mainstream processors to soldered design, some retailers and overclockers have decided to take the task themselves. As such, Der8auer and CaseKing.de have partnered up to launch a series of Coffee Lake and Core X processors which will be available in pre-binned and also special designed IHS variants.

So while the Core i7-8700K turned out to be the best gaming CPU of this year, there are still a lot of things that could have been better. The chip is great but thermals are an issue and since this is a K series processor with not the best TIM, the capabilities are hindered due to higher thermals. So the thing that Caseking and Der8auer have decided to do is offer a select range of pre-binned options at different clock rates, the result is more premium price chips that cost up to twice as much as the MSRP of $359 US.
