I love your system, but something about external radiators just makes me go bonkers (as in, hate them).
Probably because I go to LANs fairly often.
that's why there are Bitspower Fillports + Koolance Quick-Disconnects
everything separated in less than 30 seconds. Hell you could even make a second set of external tubing that's shorter just for LANs ^^
and I can use it as a heater in winter ... just ran Furmark and the Aquaero calculated 400W of heat between entering and exiting the blocks in the loop ... sure felt like that lol

So how does your GTX690 perform in Tribes / BF3 ? My 670s SLI are pretty close to perfect 99% GPU usage in Heaven/3Dmark/BF3 single player, but in BF3 Multi and Tribes Ascend GPU usage hovers mostly around the 80% mark :/
BF3 performance is still great (80+ fps when on low usage, usually 120+ fps) but this is apparently some issue with BF3 or the latest patch or something
however Tribes Ascend is even worse, drops to ~60 fps at times (from the 122 achieved with the frame smoothing .ini edit) for no obvious reason. GPU usage on the cards is less than 50% whenever that happens, but then again even at the 122 fps limit they barely have to work... 2600K @ 4.8/5.0 shouldn't be the issue right?
tested with the latest two beta's and the latest WHQL drivers btw
It reduces the voltage being sent to the CPU. I don't fully understand it, but I know it reduces your vcore and is bad for overclocking at times, since your 1.21v can actually become 1.92 due to vdroop.
Vdroop is basically the amount that voltage drops under (high) load, due to issues such as PSU and VRM quality. There's always some Vdroop, it's just that better quality motherboards with more VRM phases are less effected.
to counter Vdroop you have certain bios settings such as Load Line Calibration (LLC, for Asus boards) which reduce this effect by increasing the voltage under load
for Sandy/Ivy Bridge in general I advise against using LLC when using the +/- offset or automatic voltage, as it can lead to some weird voltage results (I've had 1.55+v on an offset that normally gives me 1.4). LLC is mostly useful for extreme overclocking/benchmarking with fixed voltages, but for daily usage I'd just use offset mode (with C1E enabled for downclocking), and then increase the offset a bit if I suspect the voltage drops too much
better to use offset and run a tiny bit more voltage on the 1600 Mhz idle (still below regular load voltage) than to use LLC and pump massive voltage under load/high temperatures ... (and over 1.35v is not really recommended for air cooled systems)
