Hi guys I ordered an Asutek WaterChill kit (Chipset & CPU blocks included with L20) and it would be arriving next week. Basically, I want to add a maze4 GPU block to this setup. The setup I am going to cool with this consists of an XP2500+ that I am going to overclock to 2.5GHz or more and an NF2 Abit NF7-S running at at least 233MHz FSB. The GPU I am cooling is a R9800Pro 128MB(Powercolor). So the total load would be 100W(CPU)+70W(GPU)+20W(N/B)=190W. Which would be better in terms of performance, getting a second radiator(BIX Pro) or using a more powerful pump(1250)? If I leave the setup unaltered and simply add the GPU block, what temperatures would I be expecting with an ambient of 30degrees?
