Hi all,

I would like to acquire some aqua-computer products. My system has already a RL solution with the following components:

i7 2600K with Apogee XTL water-block
2 x EVGA GTX 580 FTW Hydro Cooper 2
1x MCR220-Drive radiator with integrated MCP35X pump and reservoir

I want to change radiator for a bigger one (it will be out of the box, ie external radiator), thinking in a 4x120 or even 9x120 such as:

Phobya Xtreme QUAD 480 Radiator (4x120mm). Pressure: 2 bar
Phobya Xtreme NOVA 1080 (9x120mm). Pressure: 2 bar

I'm going to overclock my system (not extreme overclocking) and silent is important to me. So my questions are:

Can the Aquastream XT USB pump operates good with this loop? Will it be able to deal with the total pressure of this loop or should I choose another pump?
Are the radiators above suitable for my system or someone recommend to me another ones?

Thanks in advance and sorry all for my bad English!
