Top or bottom mount PSU?

In the linked picture? Definitly not.
The fan must face downwards, unless if there is no hole.

There's no hole!! 🙁 Do you know if the top-mounted PSUs' life gets shortened or not? Very confused,very.

Top mounted? Shortened PSU's life?
Theoretically, yes, due to temperature issues.
But, I do not know, how it is, in the real life.
All of my top mounted PSUs lived long too.
