I know it's 29 posts late but welcome to the forums. The idea is great and I've been working on a similar external cooling unit, with quick disconnect couplings. I cant help myself and please dont take this the wrong way but what you have done is not only an enormous waste of money but vastly overcomplicated and a waste of time. The best you could hope to achieve would be constant ambient temps under load, however I see the cpu is at 47c. Your never going to get below ambient temps with water cooling without the use of peltier elements. The reason I say this is because you could achieve the same performance from 1 pump, 1 radiator, 1 reservoir & 3 fans. The number of fans and pumps your running will also add to the overall noise, regardless of whether they are low noise or not. Again it's a great idea, and of course your entitled to do whatever you want. It's just a total waste of money since the 1 pump, 1 radiator, 1 reservoir & 3 fans would have done the same thing....just cheaper and more efficiently.
