I'm cooling a LOT ... and thats an understatement.

Here's the loop:

Reservoir --> pump --> cathar's LRWW block --> swiftech mcw50 --> dtek northbridge waterblock --> bong --> repeat.
The bong is roughly 4.5 feet high. The entire system is 3/8" ... except from reservoir --> pump, and pump --> case, and case --> bong. So basically all the external hose is 1/2"

Its brought my eheim 1060 to a crawl. It can't maintain the pressure needed to put water through the showerhead effectively, and water is pretty much trickling from the top down. Its quite sad, and far from what it used to be like only with the single waterblock in the system.

Now ... I need a new pump, and it needs to be POWERFUL. I think I have two options really ... an Iwaki MD 20RLT ... or the MD 30RLT

Both are 3/4" connectors, which I can of course have adapters on ... but the 20 pushes 420 and the 30 pushes 510. These are figures at 4' head, not zero. I'm not sure on the units ... I'm guessing its liters per hour ... as everything else listed on the page says GPH, but these are unmarked. Who knows ... Either way, I know both have much more flow at 4' head than my 1060.

Its a cost difference of about $144 vs $185.

I may be adding ANOTHER waterblock to the system soon ... so that'll make things even worse.

What do you guys recommend? Is the 30 considerably louder? I heard that the iwaki MD20RLT, just like the eheim 1060, is dead silent if you eliminate vibrations, but I haven't heard any feedback on the 1030. I'm looking for a very silent system ... for example, only ONE 120mm fan running at 7v in the ENTIRE system kind of quiet ... so the pump being totally or near silent is a MAJOR concern of mine.

Here's a picture of the rig:

Thanks for the help!
