I'd recommend the MCP35X personally. It's a little more powerful doing 1GPM at 6.52 PSI, and considering you'll have two decent size radiators and 3 blocks, that's a fair amount of restriction. Though you'll still only be looking at around 3-4 PSI restriction, the pump has a PWM connector which means you can run the thing at half speed even during a full load for silent operation, longer life, plus I just think the reservoir add-on looks better:



A little more elegant than this:


The MCP35X is pricier for sure, especially when you add in the reservoir and decoupling/heatsink kit (recommended).

I'm using it with my loop, but I purchased a separate reservoir that's larger (does a better job of filling in the space in this massive case).





I bought the decoupling kit, but ended up using only the heatsink (which I recommend just to add some longevity to the motor). The decoupling aspect of the kit is just four legs on rubber feet to absorb some vibrations/sounds wherever it may sit in your case. But because this pump is so small and light, a found that the absolute most effective decoupling is to just suspend the thing in mid-air. Mine is hanging by the tubing coming from the bottom of the reservoir.

Old dusty pic of it:


The pump is inaudible. May not seem like a big deal, but you'd be surprised how much vibration and resonance those motors can produce. I had a D5 with an XSPC Bay reservoir top a couple of years ago that made my whole case vibrate.
