Re: Hello, n00bie here, just watercooled 6800U
From what I read, those temps are common for Prescott's. They are high because of something to do with stepping. This cpu i have has ran like this for at least a year now, and even when I break over 80*, the system stays stable, no crashes yet.
Either way, there's nothing with the gpu block because its like a universal fit for most radeon's/geforce's.
Also, my GPU core reads 47*C at load and its after the cpu in the water loop.
