From what I've gathered you can get some small gains from going larger on the rad, but I don't really care I just want relatively silent operation with high clocks (1900s). I'd need to spend 150-200 for an x62 kraken and G12. These cards we have are also non-a's so we can't even put the higher power bios on them. I'm only considering AIOs right now and from all the videos I've looked at/articles read it's absolutely fine. I'll probably put some copper heatsinks on the memory but that's it.
