Ok, initial testing done. When I first install waterblock on mobo, I ran out of artic alumna paste, so I put it to little on, but I countinued anyway and the results with now 103W Duron (1110@2,3V) was 11 °C above water temp. And now I found out I got some as2 left, so wb off, as2 on, wb in, results 2°C drop instantly
But the damdest thing is I still didn't recieve my rma-ed axp (2months) so I can't show you how perform with 30% bigger core. I had one xp for few hours to test and I got 1920MHz at 2,11V (~120W) and the temp was lower than with that hot little Duron.
