I contacted Noctua just to get some feedback on some of my concerns:
Q 01: I’m considering buying the NH-U9S for Intel - Core i9-9900K 3.6 GHz 8-Core Processor.
Is it compatible with this CPU?
A 01: The NH-U9S can handle the Core i9-9900k - but not on full turbo: suggested maximum power limit: 215W.
About moving the cooler: https://noctua.at/en/products/cpu-cooler-retail.html?faq_view=152
Q 02: In regards to transporting I’d only be carrying the case to and from the office. In the car I plan on lying the computer on its side so that the motherboard and cooler are facing up right.
Would even this movement be a problem?
A 02: Yes, that movement might be a problem - it doesn't have to be, but we cannot be held responsible for any potential damage.
turbo = overclocking on the new Intel and AMD cpus. There is no difference there. The cpu will automatically increase it's clock depending on how capable the cpu cooler is. The i9-9900k for instance draws 95W on stock clock (3.6 GHz). When using it's turbo to 5 GHz, the cpu will draw up to 250W which is significantly more. The NH-U9S can handle 215W, thus we would ask you to limit the max. power limit in your bios to 215W. That's already a significant "overclock" (more then double the standard TDP) that is done by your cpu automatically, called "turbo". ;-)
