Ultra X-finity 600 missing fan header?

[eklass]

Hello, I have an Ultra X-finity 600 power supply. In the manual, under "connector distributions", it states the existence of a fan connector, but I did not see it in the cabling. Every other connection is present.

Any other X-finity owners have the same issue?

early revisions of these boards probably had different specs and they only show current specs on the website.
