Question about Intel Core i5-8600K

There is definitely no fan with this processor, the paperwork (warranty info etc.) is included.

No fan or cooler included, as stated in the specifications.

But why doesn't it say Box, like with the other CPUs?
Is with manufacturer's warranty, manual?

I found the tray version.
So this must be the boxed version... or would boxed mean that a cooler would have to be included?
