1 or 2 pumps

[L33T]

I already got one Petra's DDC2. Do I need another? Here's my setup:

Maze4-1 (x2)
MCW5002 (modded to TEC version))
AquaTube (here the 1/2" squeezes to 40mm and back)
Black Ice Stealth GT 240

Not for performance reasons. For redundancy, yes, if you are so inclined. The extra head pressure and flow definitely doesn't hurt lol

Are your temps bad ? if not, i wouldnt bother :)

I donno my temps; I haven't hooked anything up yet ^__^

I'm in the process of buying all the parts and building a custom case and modding the Koolance EXOS

[welshtom]

Buy a thermochill PA rad then :p

Hehe well, it wouldn't fit inside a Koolance EXOS (AL & the original).

From the your list of components I'd say you have at least 1 GPM of flow. So even if your temps were bad, a second pump wouldn't help. Redundancy is the only reason to get a second one.
