Systems specs at bottom of post....

I have a AMD XP 1800 I built a few years ago. I recently purchased a new X-Blade Case that came with a 450 L&C Power Supply, I noticed the system seemed unstable I checked Sandra 2005 and the sensor for the Power supply said it was 55 degrees C So I replaced it with a 400 watt Forton Source PSU that has 1 120MM fan. Seemed to run ok for about 6 months, then yesterday I replaced the Hard drive with a Maxtor Diamond Max 160 GB 7200 RPM Fdb ata 133 and I noticed the PSU was Scorching hot burned my fingers hot. I checked Sandra and it was 69 degrees C

I think I have decent ventalation with this new case it has an front 80MM fan a side 80 MM fan and a rear Pabst 120MM fan. The board runs at 34 degrees C and the processor around 44-51 at load. Also I have fairly decent cable layout, nothing blocking airflow, and round cables for ATA devices.

I am at a loss to figure why I can not keep a PSU in this machine, any suggestions will be greatly appreciated.

is the PSU fan spinning?

On both PSU the fan was spinning, but on the Forton the fan has been making quit a bit of noise. Even when the fan was working correctly the power supply always seemed warmer then it should.

As of right now I put the L and C PSU back in, the sensor shows 53 at load and goes down as low as 32 C
