Sorry to be a pain chaps.....

Getting closer to D day so want to get optimal flow order.....

Here are my parts

RAD > RES > CPU BLOCK > GPU > PUMP

What order should I go for?
 
You want the reservoir before the pump to make it easier to fill the loop, as you really don't want to run the pump without any water in it. Beyond that, doesn't matter, put them wherever looks nicest.
 
I went with WC for the first time a few months ago.

I originally I had it:

Res > Pump > GPU > CPU > Rad > Res

A week ago I changed it to:

Res > Pump > Rad > CPU > GPU > Res

There is hardly any difference from what I can see, certainly not anything significant.
 
The way I see it is:

1. Hot water from the CPU goes direcly into the rad, the hotter the water is the more it can cool down.
2. The cold water from the res now goes into the GPU, which warms it up again.
3. The warm water from the GPU goes into the res where it has time to settle and cool down a bit.

In real world applications the difference between setups is completely negligible though, go for whatever works/fits/looks best.
 
I suspect almost everyone assumes it will work like that Strawberry, only to discover they're wrong shortly afterwards. The flaw in this analysis is that the water is flowing fairly quickly, and for noticeable temperature variations in the loop it would have to be flowing very slowly. It's not just a negligible difference in reality, it's a negligible difference in theory as well. A kind soul ran the numbers on here a while back, I'll see if I can find the thread

Found something similar, fornowagain on why mass flow rate doesn't matter very much, [post=15007563]here[/post]. Someone took photos of his watercooling system with a thermal imaging camera (whatever it's meant to be called) a while back, but I can't seem to find that either. Not doing well today.

Nice one mmj, that's exactly the thread I had in mind. Cheers. I must learn to preserve bookmarks between reformats.
