Motherboard Asus P4G8X
2x 512 MB Corsair XMS3200
PSU monitor MB500
Case CS601 Miditower fanless, closed and no air flotation

Results :
 
The Prosilence PSU is very stable in every voltage level.
The temperatures were very good at 90% of the tests with 40-44°C at the aluminuim heatsink outside and 32-40°C at the PSU case.
Only one time we measured during the PC mark 2002 test 46°C . The whole test we repeated 2 times and got the same good results.

The System :
Everything open, P4 @ 2.8 Ghz, Radeon 9700 Pro with heatpipe,Seagate HD 120 GB, no Floppy drive, no CD or DVD drive, no fans.....

played the new Unreal 2 game for 3 hours and made some measurements. Some parts like capacitors and transistors reached up to 56 Celsius which is absolutely normal. The temperature on the heatpipe cooler was 25- 27 Celsius, at the same time the outside cooler reached up to a maximum of 41 Celsius. Hey that's cool !
