Also, why then are high flow pumps used? 1/4 is a really small diameter, and you need a high pressure pump, yet most recommend the 655 over 355?
Sorry for the noob questions, just wanna make sure i understand whats what.
i think i understand what you really want to know.
the answer is resistance is cumulative throughout the loop so the smallest diameter the water travels through isnt going to set the whole loop at one resistance.
play with this for a bit till it really starts to take hold

no it doesnt. otherwise there would be no flow in a 1/4 inch german loopbut that one small diameter puts alot of resistance on the whole loop -
equate to what you just said.....but that one small diameter puts alot of resistance on the whole loop -
the rad will be mounted outside of the case for better temps(you are in effect heating up your case by using the rad inside of it). I still have to come up with a way to mount it on the outside, any ideas?
what do you think of the vario vs 355 with top?
therefore you could use 3/8 tubes as long as you can fit them onto the 1/2...(which is not that hard if you have the right material and hot water)
On a side note, is it true that a properly mounted 355 with external res mod makes no noise? I am having trouble deciding whether to get that or a mcp655, I am going with a HW 560 GTX for my rad because I found one on ebay new for $130 shipped.
Dont want to end up with a noisier than needed pump, and swiftech say that the 355 is noisier, true?
I have read people saying both.
but how does this equate to what you just said.....
Not quite true. Have a look at this P/Q curve graph. For all but one of those aftermarket tops the stock top has higher pressure....but only below 1.0GPM (less than that isn't ideal for our purposes). Above that, all of them produce more pressure per flow than the stock top. Here's a link to the whole article. Well worth a read.Simple, I said that 1/4 would be a decent size to allow for enough flow in watercooling applications - I didnt say it wouldnt restrict the flow of a big pump - it would, in fact, idealy you would use a low flow high pressure pump, such as the 355 - which is why it comes with 3/8 in stock form, modding it just makes it into a higher flow pump but with less head.
