A report from Chinese-language site XFastest contains a slide reportedly showing Intel's cooling strategy for upcoming retail HEDT (High-end Desktop) Skylake "K" processors.
Typically Intel CPUs (outside of the current high-end enthusiast segment on LGA2011) have been packaged with one of Intel's ubiquitous standard performance air coolers, and this move to eliminate them from future unlocked SKUs makes sense for unlocked "K" series processors. The slide indicates that a 135W solution will be recommended, even if the TDP of the processor is still in the 91-95W range. The additional headroom is certainly advisable, and arguably the stock cooler never should have been used with products like the 4770K and 4790K, which more than push the limits of the stock cooler (and often allow 90 °C at load without overclocking in my experience with these high-end chips).
Aftermarket cooling (with AIO liquid CPU coolers in particular) has been essential for maximizing the performance of an unlocked CPU all along, so this news shouldn't effect the appeal of these upcoming CPUs for those interested in the latest Intel offerings (though it won't help enhance your collection of unused stock heatsinks).
