Serial or parallel GPU and VRM loop?

[Snowman] · 02-28-2009, 02:35 PM

My new setup is going to have.
2 Alphacool VRM Cooler ATI
2 DangerDen LowProfile Maze5 GPU
1 DangerDen MC-TDX
1 Watercool MO-RA 2
and Swiftech MCP355 with a XSPC Laing DDC Plexi cover
All 1/2 tubing

So how should my loop go for best performance?

Pump-> CPU-> Rad-> Y-split-> Gpu-> VRM-> Y-split->
------------------------------------> Gpu-> VRM->

or Pump-> CPU-> Rad-> Gpu-> Gpu-> VRM-> VRM->

I also have the same question but with this hardware:

Processor Block: Swiftech GTZ (775)
Video Card Block: Swiftech MCW60-R2
Radiator: Swiftech MCR320
Pump: Swiftech MCP355

I've heard that using a split after the radiator may cause too much flow to go to where it is the least needed (in the video card) instead of the processor. but this will cause alote of water to flow which will make better cooling in the radiator, and may eventually make colder water to go into the processor.

Using a Y isn't going to help your flow rate or increase radiator performance.
