Series or Parallel

I am setting up my first water cooling system and i am wondering if anyone has any advice on wether i should connect my radiators in series or parallel

I asked the same question a few days ago, running dual rad in parallel is allot better then series.

Here is a thread that may help

Do you have proof? Ciffer, do whatever lets you use the least ammount of tubing.

Depending on your system, it is hard to predict which would be better. Try both arrangements and see what works best. The disadvantage to series is resistance of the second rad. The disadvantage to parallel is adding 2 Y connections and more tubing (compared to series). For people with larger tubing and heatercores (low flow resistance), series will more likely be better and easier.

For my system, I'd use whatever setup was cleaner from a tubing perspective, but I'm a little lazy at times.
