then is certainly a little girl when it comes to temps. i was using the stock water block that come with my Tt bigwater cause i never got round to buying a new one and i had a limit of 2650 on core 3 before it BSOD like hell. got me a D-Tek fuzion V2 it now runs 13C cooler just by changing the cpu block and core 3 now stops at 2780 wi\hich is due to the temps which load at 48C and idel at 32C.
