Dual Rad Question.

extreme · Jan 12, 2004

I was just thinking, i know parrel is better then serrial in a dual Rad setup, but what about having it setup like this.

PUMP>RAD>CPU>RAD>PUMP

With a T-line

Think there would be any improvment cooling wise?

results will be the same as a serial setup.

Aight, thought so, just was not sure.

Thanks for the help.

Sounds like a pretty careless blanket statement to me. Care to share your reasoning with all of us?

I use Pump -> CPU -> Rad -> GPU -> Rad -> Res -> Pump.
For me this setup was best by test, 2°C better than
the 2 Rads together with T Lines.

I don't know the theoreticals and couldn't find any info so I just tested them both to find out which worked better. YMMV

placing the rads in parallel would make the hidrodynamic resistance lower.

as they sum (1/R1+1/R2 )^-1 , being R1 and R2 the resistances of each radiator .

Several people here, including myself, have experimented to answer the pump-before/pump-after the rad question. As far as I know, nearly all experimenters found no difference in cpu temperature when moving the pump.

In the setup described, if you remove the pump you simply have the three components in series.

Oh! Now I see what he was asking. Put the radiators in parallel.

yah i have read that the difference is minimal and not really worth that much effort
