Serial Vs Parallel
 

Hi, i've got a RBX cpu block and a maze3 w pelt VGA block
I was wondering what the best configuration should be:
- both blocks serial (water runs faster, but heats up)
- both blocks parallel (water runs twice as slow, but both blocks get cold water)
- both block serial and 2 radiator between (block, rad, block ,rad, res, ...)

in my humble opinion

that pelted Maze3 will drop a lot of heat into the loop, having a radiator is essential if you want good performance, if you keep the flow high I think it is feasable to run

PUMP -> RBX -> MAZE3 -> RADIATOR -> RESERVOIR

without much loss in performance, the Maze3 has low restrictions, while the RBX will take away more power from the pump, so a high end pump is advised

Re: Serial Vs Parallel
 

did you know that the water temperature is almost constant in the loop?

if water enters a block at 25°, it leaves the block at 25.3°C or so. in any case, it doesn't make a difference in what sequence you place everything

if you want two radiators you'll need a good pump. even then, two radiators are flow killers. if you use two radiators anyway, place them in parallel

well i got 1 single rad (BI extreme) and i was planning to buy another single an put it in between the blocks so the water runs trough a rad before entering the RBX, and into another rad before entering the VGA block, ive got a 800l/h pump (watertank 800, pump+res)

Do-able with your pump :).

I've had a Hydor L20 which pumped through an Evo Triple and a BI Pro without any problems.

the RBX needs a pretty powerful pump to work optimal.

you mean like >700l/h?

L30 will be better then L20 in my humble opinion
