That is exactly what I was saying. I prefer a visual que, a reservoir with plexi glass window of some sort that helps me detect the current water level at a glance. good instructions. i never mad those statements. i didn't say anything about 7 shrouds and i am not sure if you are refering to my koolance suggestion with your 2nd claim. Again, I have not suggested that shroud. The shrouds i recommended was The TFC extender amd the Swiftech RadBox. correct, i like nickel better and prefer to make a habit of using it for that very reason. The less mixed metals are in the loop that can oxidize the better, to me anyway. so if you have the option to pick a nickel block then thats the route i would go. As dividebyzero explained Ni=Nickel does not oxidize with Cu=Copper. I am not that deep into chemistry but assuming this Ni2+ and Cu2+ then there should be no reaction. I was rather under the impression that this is Trillionsin's entry into water cooling, not that his, your or my suggestion would lean towards an entry level system. It clearly says in the 1st post that he is new to water cooling. You as well ill advised to use a single 360 radiator for a CPU and 2x GPU's. It does not matter much what pump you are using or how many fans you are putting on the radiator, if there is not enough heat removal the heat isn't removed. i don't disagree with the pump. The D5 is certainly a higher performing pump and would be a better choice, again I wanted to give some variety. The DDC is a good pump as well. Over 12v, not so good but I wouldn't run that pump over 12v anyway. The DDC is a nice, small and quiet pump. Yes you can quiet down a D5 Vario but then you also lose performance and mind as well go with the DDC... unless you are tinkering on the setup the whole time anyway.
