Im currently making my first water cooled system. I have the resevoir, heatercore, fans, tubing and copper blocks on order. My last item is a pump i want to go with the via 1300 because of its reviews and price. In the future i plan on running the resevoir and heatercore within a mini fridge or freezer so im gonna have to have some tubing going out of my case and into the cooler, if i purchase another via 1300 pump in the future when i do this mod, would running these pumps in series help balance the load and increase the flow back to a descent rate since im basically addinga few feet of tubing? Cuz still $44 for (2) via aqua 1300's is still cheaper than these $75 "retail" super pumps that really arent that much more super.

Thanks guys.
 
I have a via 1300 and an eheim s600 running in series in my setup i have about 15 ft of hose. 10 ft of 1/2" and 5ft of 3/8" and i found that when i added the eheim 600 i got about 25% more flow rate then without it, however my temps only went down about 2 deg F

i would guess that two 1300 would give you 50% more flow but i am not sure really high flow is what you want if you are looping into a mini fridge i would think the longer the water stays in there the cooler it would be.

No, that's not how heat transfer works. Faster flow will yield you better heat transfer, generally speaking, so you don't want the water to move slower (stay in there longer
).


Plain old tubing is not that restrictive. Compared to the resistance you already have from the block(s) and radiator, a few more feet of tubing is most likely a small increase. If you're worried about it though, I would just get a pump with a better head rating. Danner pumps are supposedly pretty hefty and not too expensive. However, they are notorious for leaking from the housing O-ring, so a little elbow grease might be necessary to make a good seal there.
