I have recently purchased an XCLIO 450 Watt PSU from Newegg , and while it is a great power supply, it is alittle on the loud side. Im not overloading this psu in any way, so would it be safe to swap out the stock fan with a Yate Loon ~35 cfm/23 db fan?

Yeah, I've done this before with several PSUs and as long as you don't go poking around in there it should be all fine.
Either the PSU has a fan plug on it or you can cut and resolder the wires.

Yep. Piece of cake. Just don't make the same mistake I made with one....
I had a 600W with thermostatically controlled fans. Even then, I thought it was too loud. So I took the fans out and put DIFFERENT, quieter, thermostatically fans in there.
Oops.
Apparently, the thermostatic control for the fans was on the PSU's PCB. So when the PSU was cold, the voltage was around 5V AT THE CONNECTOR. The fans were cold too, so when they tried to run at the lowest RPM with only 5V... let's just say seeing them twitch was a big deal.
The PSU works fine. Once the PSU heats up the fans do start spinning. It just makes me nervous when they don't spin at all... then I can't tell if the fan's dead... or if it's just too cool to spin up.
