hey I'm really sorry to post this but i have been browsing a lot of water cooling threads and none seem to answer the questions i want to know. Firstly i've been looking into the noob kits. I think i'm settled on the EK HF 240 kit. I've looked at most of the available kits, Larkooler don't cover my price range with a decent pump. So there out. Swiftech i can't seem to find anything that suits me. Leaving the XSPC rasa kit with the 750L/ph pump and front mounted drive bay reservoir. Or the EK with the standard reservoir and a 800L/ph pump. EK have the edge for what i want to do. Since I want to be able to fill and drain screwlessly. Firstly before i begin, The question that nags me more than any. Is there a standard system for waterflow. CPU->rad->res->pump->CPU I can't find anything on the actual mechanical layouts of watercooling to give me an indicator of what works best. all of my other questions have already been answered a million times by you people already, You must get sick of it. So there will be no barbs V/s compression mounting questions. i can work that out for myself with the search function this is a very simplified version of what i had in mind. Keep in mind this is basic. I'll start at the cpu. Cpu to rad. simple. Rad to reservoir. (res) Note the resovoir will be mounted so the pipes connect at the top. I'll explain this in a few mins. Res to pump pump to cpu. Filling and draining. Filling first. The pink intersection of the pipework is a T section with a capped end. The first intersection between the rad and the reservoir is the fill point. By laying the pc down drive bays to the floor i should be able to get a good fill on the loop. Getting most of the air out of the rad and out of the reservoir. Cycle the pump and top up. this is the reason to mount the reservoir so the pipes are a top filling as the air should go to the rad when i settle the pc in the correct orientation. A simple bow in the pipework near the T section will mean i can get the last of the air out pretty fast i hope. To drain the case it placed on it's back, I/O plate to the floor. by loosening the fill and then loosening a drain that is place discretely on the underside of the case i think it should drain air block free. Will this work? many thanks for reading this watercooling threads Probably need some sort of sticky at some point.
