If the 5.5 ghz clock holds to be true, not sure if my 240mm aio cooler will be up to the task.
Intel recently removed the all-core turbo spec from official listings, now only max single core turbo and base clock.
Usually, it's the base frequency that determines which TDP rating an SKU falls into. Sometimes an SKU is deliberately put into higher TDP ratings to ensure OEM cooling companies don't cheap out on heatsinks.
But single core turbo doesn't have much TDP impact on the total because the other cores are either idle or straight up downclocked. Like that recent mobile quad-core rated at 15W TDP, base clock 2.0GHz with Turboboost to 4.5GHz-- for some reason, those hyping the processor convinced themselves 4.5GHz was all-core.
If single core took up all the TDP with other cores off, four of them means a 4.5GHz quad-core at 60W or more given voltage adjustments. That's 7600K territory at 14nm. People reacted to a big number; likewise, this 8-core at 5.5GHz isn't an all-core Turboboost. One could hypothesize overclocking all cores to 5.5GHz could be possible, but I'll wait for Siliconlottery's assessment.
As for your heatsink/cooling, TDP ratings encompass multiple SKUs regardless of specs, this is so OEMs don't have to change the cooler for every CPU. In other words, if Intel puts 9900K in 95W TDP, then any cooler ever made in the last decade for 95W TDP will work. That's the whole idea of TDP, it's a ratings category, it doesn't represent actual wattage.
