Im rebuilding my entire cooling system on my computer, I have a Cosmos case AMD Phenom 9850 Black Edition 4870x2 and then the rest is useless stuff like 4 gigs of ram and 2T of space currently im running a nautilus 500, and im going to replace it with a custom cooling system The reason im doing this is because I dont want the Nautilus outside my pc anymore and going to replace it with one that goes all inside. And also my computer crashes playing games because my gfx 4870x2 get wayyyy to hot, and it wont automatically adjust the fan speed like ive seen other cards do, So i manually use expertool from ati to blast the fan at 100%, but its still not enought... so im going to replace the entire fan with this: EK Full Cover Nickle Waterblock for 4870x2.... I bought the thing but what I need help with is choosing the rest of the stuff... I dont have fitting tubes or anything. Can you guys help me out and tell me whats good to get? Im using arctic silver 5 thermal compound for all my waterblocks Im just going to cool down my 4870x2 and my amd 9850 black edition What waterblock should I get for the 9850 What resirvor should i get that will fit nicely in the cosmos case? and what radiator should I get that will fit nicely inside there 2.... ANd the most important part is choosing the fittings, I'm completely lost with the fittings terminology and need help choosing it for my cooling, Please choose good high end products, and dont go over board telling me to get a magicool extreme 4 radiator which is way to big and which I dont need for a 4870x2 and 1 processor... Thanks in advance.!
