I get 50 load, 35-40C idle. I'm running liquid cooling at stock speeds. On air I was getting 80C load at stock speeds, 55-60C idle.

Edit: x1950pro - 80nm
x1950xtx - 90nm

Chozart or someone tell me what is the stock voltage for the Sapphire X1900XT? I used Chozart's ATI Tool guide and now I accidentally have my stock voltage on 1.4..something. I want to set my default back to what it originally was. I think it was 1.3..something. ANyone?
