Considering the size of the heatsinks that come with them and the piddly little fans that run on them, they probably run much less. Keeping in mind that a BIX-II can handle a pair of Xeons at 3.7Ghz, i think a BIX-III should be able to handle it  |
those are very low restriction blocks in the Xeon system (RBX). the koolance parts are more restrictive and the chipset block is ungodly restriction. it's going to kill the flow rates and hurt his performance overall.

Not having a go at you, but i honestly don't understand the whole "omfg 2 loops roxxor teh big1!" thing that is going around.

it's mostly dependent on the type of blocks you get. let's say i want 2GPUs (Maze4), a Storm G4, and a Maze4 chipset block. the G4 is an impingement block, so anything that restricts flow will significantly hurt performance. so putting the CPU in one loop with, say, a BIX1 and the other blocks in another loop, with a BIX2, then the impingement block isn't restricted. there's no point using one loop if you have all those parts and can easily create 2 loops. then you have heat dump from only one pump and much less restriction in each loop.
