GPU Sli 2 Way Serial or Parallel

post #1 of 11
Thread Starter 
Hello Guys , Just finishing up the project had a question regarding what should i use with the 2 WAY GPU i do have extra fittings as well , So help me out how serial or Parallel loop works with the GPU any guide or examples ?

Thanks



My work in project Sample . there would be same 2x GPU blocks.

With serial you have one connection between the two so the fluid passes the first block and then the second one. Parallel is when you have two connections between the blocks so the fluid flows through both blocks at the same time.
As far as I know parallel results in lower restriction.

I'd recommend parallel.

Lower flow restriction and both GPU's get water from an equal temp. In serial, one GPU runs sightly hotter than the other one.

parallel, halves to total flow rate, if your flow rate is 1000L/H then your only geting500 l/h on each gpu block.

Parallel will half the resitance of the waterblocks, so if you get more total flow by putting it in parallel you could benifit from it.

Otherwize, put it in series

With personall testing, gpu blocks has less resitance than a 240MM 120MM 360MM radator,
however, with a doubble thickness, which finns are hooked in parallel, water resitance is halfed, a 140,280 radator also has low resitance.

Bascally saying, if you have any 240MM 120MM 360MM radator, all of the resitance would be comming from there, flow rate would be detrimined by the most resctrive component in the loop

I have a flow meter, with 240MM radators, my flow meter moves extremly slow.
And using 280MM or a thick radator, the meter goes flying fast

Using a T or Y fitting, two of them, use one before entering gpu and using one afer leaving gpu

I recomend hooking gpus up in series, your not going to benift form lower gpu block resistance.
Only conserquense for series is water heating up from first gpu and going into second gpu
