Hello Everyone,
I recently bought Antec BP450S PSU which is a level below VP450P. I test ran it in the first day for 1 hour with the PSU fan spinning and PSU was cool. In the second day I started memtest86 and went away when I came back after 7 or 8 hours I noticed that PSU cooling fan was not running and the PSU walls were heated. I found that two pin PSU cooling fan connector was disconnected. I somehow managed to connect the pins without removing 'Warranty void if removed' sticker. Now the fan is running and PSU is running good and cool.

I have two questions to solve
1. Whether quality of components inside PSU were degraded during that 7-8 hour run without fan and might have damaged PSU?
2. How the 2 pin PSU fan connector disconnected?
(All I can guess is the connector was connected very loose in factory itself and mingled with other wires which when pulling, connection came off).

My test setup during that 7-8 hours:
Intel core i5 3470
Gigabyte Z77 board
8 gb ram(2x4GB)
keyboard
usb pen drive
I bread-boarded and PSU was outside.

This is entry level power supply from antec.
 
Solution
Hard to say whether any components were degraded. I don't know if the PSU has thermal overload protection or not, but as long as it's working fine right now, I would say it's OK.

The cooling fan may have been barely attached from the factory and came loose during use or handling.

I am relieved a little that PSU is completely outside on desk so there is airflow and the load is under 125 watts or so as very few components were connected.

I also use AMD fx8350 with gt210 card with another Antec PSU. The PSU(without fan spinning) which powered the test system got as hot as the PSU (with fan spinning) which powered the FX8350 system.
