wtf... all the misinformation.... confounding my feeble brain....

wasn't all this shit was explained in the water cooling myths thread by greenman...? :shrug:

"Myth: Water must slow down to fully absorb heat.
Reality: In a closed loop, a given water molecule actually spends the same amount of time in the radiator no matter how fast it is moving, as long as the water is indeed moving. If this is a difficult concept to understand, think about a racecar on a track. If the track is 1 mile (5280 ft) long and the car is driving at 60 mph, the car will spend about 1 second in a 100 ft stretch. Think of the 100 ft stretch as the radiator. Now, if the speed is doubled, the car only spends ½ a second in the 100ft section, but it passes through that same section twice a minute, so it spends a total of 1 second in the 100ft section per minute."

"Myth: A pump's flowrate is the only consideration to make when choosing a pump
Reality: A pump's maximum head pressure is just as, if not more important. Waterblocks are relatively restrictive, and many aquarium pumps are not made for that kind of restriction. In order to estimate one's flowrate, Calculate all pressure drops, then overlay on top of the pump's P/Q curve. In other words, it's not easy, but consider head pressure, too."

"-> every time you see a component's performance curve indicating improved performance with a higher flow rate, accept that that component can never perform better at a lower flow rate

-> since both wbs and rads always perform better at higher flow rates, it should be accepted that a higher flow system will always have a higher performance capability (assuming appropriate component selection)

the actual cooling capability of a system will depend on the capability of the components, and their compatibility wrt achieving the system design goals"

note the word "compatability"
