They did have the fan issue.

That was blown out of proportion though. Valve sourced different fans from different vendors, and one of them were slightly louder than the other. It's unreasonable to expect identical behavior with different fans, and in the grand scheme of things, they performed the same.

Valve has since done some fan curve optimization, and it really is a non-issue today.
