How to properly install a PSU with a large fan in a server case?

Question

Iron

There is a case chenbro sr107 . As you can see, the PSU compartment is separated from the main space by a solid wall. Will the Aerocool higgs 750w PSU survive in such conditions? When installed with the fan down, it will lie on the wall, and when installed upside down, the gap between the case roof and the fan mesh will be around 1 cm or less. At the moment, in the PSU area, the case cover noticeably heats up from the PSU, hot air constantly flows. What can be done besides replacing the bp / case?

Answer 1

It can be seen from the fan (it sucks air from the case) that this PSU model must be installed from below, otherwise it will drive hot air away.
In any servers, the principle "from the front - the influx of cold, from the back - the outflow of hot" is used, which is why there is such a separation of air flows near the PSU.
