Thx, thing fan rpms are controlled by PSU itself. Maybe PSU has some sort of circuit and controlling the fans through voltage.
Are you using some sort of splitter adapter to connect both of the fans to 1 PSU header?

Could be voltage or heat.

Yes - see photo above.
 
so the top of the original G5 PSU modular enclosure can be put back on happily with no clearance issues with this scalped RM750i?

Yes, but check the clearance. Make sure the new ATX power supply is set at the bottom of the original G5 PSU case.

If the top of the original case is put back on, what's the path of the hot air from the coils and caps? It doesn't look like it would be able to continue travelling towards the rear of the case (blocked by the back wall of the PSU), and the case top would block its upward path. So where does it end up going?

Yes, the path is restricted - and retrofitting an original PSU case is not recommended if your G5 Hack has a lot of RAM or graphics that draw a lot of power.

The PSU in post #7 has a moderate power draw and the fans seldom spin.
