tline fillport -> pump -> block -> rad
or
tline fillport -> pump -> rad -> block ??

my parts:
swiftech mcp350 (laing ddc)
swiftech apogee
swiftech mcr220 (dual arctic cooling af12025 fans).


thanks.
 
Do whichever one uses the least amount of tubing. The order of the loop doesn't really matter. The only thing you want to pay attention to is ideally your fillport or resevoir will be right before the pump, because this makes priming the pump and filling the loop much easier.
 
pump> rad> block. atleast majority of people that have water cooling installed have recomended this order to me. common sense really.

Please see the post right above yours.

Whichever gives the cleanest tube routes FTW. Lay out the order based on the shortest total loop length, and the fewest tight turns. Keep it clean and you can't go wrong.

Putting the rad right before the block might net you at best a 1-2C temperature difference - all other things being equal. Do some reading if you care about the details, but the total delta T between the hottest point in a loop (right before the rad) and the coldest point in a loop (guess where) is not very significant. And it gets smaller the higher your flow rate is (common sense there).

As for the T-line, everybody else has taken care fo that bit of advice.
 
It doesn't really matter. Consider that you have the following setups...


Pump - Rad - Block - back to pump

or

Pump - Block - Rad - back to pump


Technically, the rad is always AFTER the block... Water is ALWAYS being cooled before it goes back into the cpu, whether it's cooled before the block, or after it, you're going to have the same cooling potential.

Now, some blocks benefit from being right after the pump, and regardless of what everyone says, this is in their instructions. Blocks like the storm and TDX say that it should go Pump to Block... And I'd follow these instructions.
 
I'd say block straight after pump, just incase you would gain some performance from a little extra head pressure or something. It doesn't really matter where your rad is, the temps of the water in your entire loop will probably only vary by half a degree or something over the entire loop
