Hello Extaze,
I tested my card a x1900GT with the same clocks and almost the same voltages you have.
Everything was set the same except my memory voltages were set at: 2.203 for both settings.
And I ran the 3d tool in ATI Tool , and I got the same temps you did 93 degress celcius.
But it probably would have went higher if i left it run.
And my cooler is the Sytrin VF1 Plus at high speed, so I guess your temps are normal at that voltage.
I think the voltage is set too high for the memory , I don't think it can take that much.
I was getting many artifacts for mem. at 2.203.
So I set the memory back to :1.84 volts, the core left it at 1.5 and the VDDCI at :1.437.
And I got 95 degress celcius running for 15 minutes.
So I added an exhaust fan in the middle of my P180 case, I took the 38 mm x 120 mm
that came with the case and set it up to exhaust the hot air.
And it worked a bit , now instead of 95 my temps are : 91 degress celcius.
Hope that helps.
Thanx PAPADOC, finally I have a Gigabyte 7300GS 'fanless' and I am gonna buy a MSI 7900GTO (If I can).
For information, I had the same results with the Zalman vf900 (90°C and more) with a overvoltage of 1.5v and if I remember, I didn't touch the others values.
But in 1,4v, the temperature was ~75 - 80°C on the card.
